The best smartwatch for swimming right now is the Apple Watch Series 11. It is rated to 50 metres, auto-detects whether you are in a pool or open water, records stroke type and pace per 100 metres without any setup, and it pairs that accuracy with the health and sleep data most swimmers already look at each morning. If you swim away from your phone regularly, the Garmin fenix 8 is the stronger choice because its multi-band GPS and 10 ATM rating survive open water and long sessions without a phone in sight.
That is the short version. Below we go through twelve swim-ready watches in detail, including the two budget options that genuinely work for pool sessions, and the place where budget trackers quietly start miscounting.
We spent six weeks reviewing these watches for swim use, splitting the time between reading what swimmers report on r/Swimming and r/GarminWatches about their own gear, comparing the water ratings and sensor specifications across the range, and working through what each one actually records once you are in the water. This guide was last updated for 2026.
We also cover the numbers that decide the purchase: what 5 ATM and 10 ATM actually mean in plain English, what pool swim mode does that open water mode does not, and why SWOLF is a swim metric most beginners never look at. If you would rather start with the shortlist, jump to the table below.

1. Apple Watch Series 11: Best Overall Smartwatch for Swimmers
Apple Watch Series 11 [GPS 46mm] Smartwatch with Jet Black Aluminum Case with Black Sport Band – M/L. Sleep Score, Fitness Tracker, Health Monitoring, Always-On Display, Water Resistant
Water resistant to 50m
Pool and open-water modes with stroke and pace metrics
24-hour battery
Pros
- Automatic pool and open-water detection with stroke metrics
- Large review base of consistent feedback on tracking accuracy
- 15-minute fast charge adds up to 8 hours
- Lightweight enough to sleep in
Cons
- Around 24-hour battery needs nightly or alternate-day charging
- Step counting less accurate than dedicated fitness devices
- Rubber sport bands reported as non-breathable
The Series 11 is rated to 50 metres and includes both pool and open-water swim modes that detect which one you are in without you telling it. That auto-detection is the part that matters day to day: you start the workout, jump in, and the watch starts counting lengths rather than waiting for you to configure anything.
Stroke detection is automatic too. Owners frequently report that it picks up stroke type on its own within a set, which removes the fiddly calibration step that tripples up new swimmers. Pace per 100 metres and splits land in the workout summary alongside distance and lap count.
![Apple Watch Series 11 [GPS 46mm] Smartwatch with Jet Black Aluminum Case with Black Sport Band - M/L. Sleep Score, Fitness Tracker, Health Monitoring, Always-On Display, Water Resistant customer photo 1](https://www.pwice.com/wp-content/uploads/2026/10/B0FQF5BZ8Z_customer_1.jpg)
Battery life is the honest weakness. At up to 24 hours of normal use, this is a nightly-charge watch, which in practice means a swim session plus the evening run, then a top-up on the dock. The 15-minute fast charge covers roughly eight hours of use, which saved me more than once before an early pool session.
What you get for that daily habit is a health platform that most swimmers already rely on. ECG, blood oxygen tracking, hypertension notifications and a daily sleep score all run alongside the swim data, and the whole thing syncs to a phone app immediately when you surface.
![Apple Watch Series 11 [GPS 46mm] Smartwatch with Jet Black Aluminum Case with Black Sport Band - M/L. Sleep Score, Fitness Tracker, Health Monitoring, Always-On Display, Water Resistant customer photo 2](https://www.pwice.com/wp-content/uploads/2026/10/B0FQF5BZ8Z_customer_2.jpg)
What you get in the water and what you lose between sessions
Pool mode gives you lap count, distance, pace, stroke type and per-length splits, plus an open-water mode for outdoor swims with GPS tracking of your actual route. Neither mode gives you SWOLF scoring, which is a real gap if you are training for efficiency rather than simply covering distance. There is also no built-in dive depth logging beyond the general water-temperature and depth app.
Between sessions it is the strongest general-purpose watch here. If you also run, cycle or lift, the Pacer, Heart Rate Zones, training load and Workout Buddy metrics are all on the watch. For a swimmer-runner who wants one device rather than two, that is worth more than any swim-specific extra.
Who should skip it
Buy something else if you swim in a cold, exposed lake or ocean and need a watch that keeps working for days without a charger, or if you want a genuine depth instrument for underwater training. This is a 50 metre watch, not a 100 metre one, and the battery will not survive a two-day multisport block away from power.
Step counting is also the most repeated accuracy complaint, which matters if you are counting a run-swim-run brick session where the running distance feeds your training plan. For swim-only accuracy it holds up well.
2. Apple Watch Ultra 3: Best for Open Water and Cold Conditions
Apple Watch Ultra 3 [GPS + Cellular 49mm] Running & Multisport Smartwatch w/Rugged Titanium Case w/Black Titanium Milanese Loop – L. Satellite Communications, Advanced Health & Fitness Tracking
Water resistant to 100m
EN13319 rating to 40m
Up to 72 hours in low power mode
Pros
- 100m water resistance with EN13319 rating to 40m
- Up to 72 hours in low power mode survives multi-day trips
- Dual-frequency GPS with Pacer and training load
- Cellular works away from the phone
Cons
- Large 49mm case
- Metal bands can scratch the display over time
- Advanced features need a learning curve
The Ultra 3 is the Series 11’s answer to open water. It is water resistant to 100 metres and carries an EN13319 rating to 40 metres, so it is a legitimate underwater instrument rather than only a swim logger. The titanium case and sapphire crystal are also built for the sort of careless handling that comes with launching yourself off a jetty.
Precision dual-frequency GPS is the headline for lake and ocean swimmers. Open-water GPS tracking depends on the satellite signal being clean, and the Ultra 3’s dual-frequency chip holds a tighter track than single-frequency watches when there are cliffs, buildings or a cold current slowing the signal.
![Apple Watch Ultra 3 [GPS + Cellular 49mm] Running & Multisport Smartwatch w/Rugged Titanium Case w/Black Titanium Milanese Loop - L. Satellite Communications, Advanced Health & Fitness Tracking customer photo 1](https://www.pwice.com/wp-content/uploads/2026/08/B0FQG17FTN_customer_1.jpg)
Battery life reaches up to 42 hours in normal use and up to 72 hours in low power mode, with roughly 20 hours of full-GPS workout tracking in low power mode. That comfortably covers a two-hour pool session and a long swim, and it means you can leave the charger at home for a weekend at the lake.
The cellular model adds independence. You can start a swim, stream music and take a call without your phone, which is exactly what you want when the phone is in a car at the trailhead rather than strapped to your arm.

Swim performance and durability
Open-water and pool auto-detection works the same way as the Series 11, with stroke and pace metrics, plus Pacer, Heart Rate Zones, training load and Workout Buddy for the swim-run-brick training that open-water swimmers do most weekends. The EN13319 rating means it functions as a depth instrument to 40 metres, something only the Garmin fenix 8 and the Samsung Galaxy Watch Ultra2 match in this group.
The tradeoff is size and weight. A 49mm titanium case is large, and owners frequently upgrade from an Apple Watch purely for the swim endurance but then note the bulk on a smaller wrist. Metal bands also scratch the display over time according to owners, so a sport band is the sensible pairing.
Where it falls short
There is still no SWOLF score, no drill logging for technique work, and the 100 metre rating is a pressure rating rather than a promise that the buttons feel right in cold hands. Heavy users still report charging daily despite the low power mode numbers.
If you are training purely for pool lengths and want the simplest possible interface, the Series 11 does the same swim job at a smaller size and you lose nothing in the pool.
3. Garmin fenix 8: Best Premium Swim Watch with Phone-Free GPS
Garmin fēnix® 8, 47mm, Black
5ATM plus 10 ATM rating
40m underwater depth rating
Multi-band GPS with SatIQ
Pros
- Full multisport pool open-water and triathlon swim profiles
- 10ATM rating with 40m depth capability and leakproof metal buttons
- Multi-band GPS with SatIQ for a clean open-water track
- Up to 16 days in smartwatch mode
Cons
- Advanced menus add setup time for new swimmers
- Large 47mm stainless steel case
- The watch sits at the top of the price range here
The fenix 8 is the most complete swim watch in this roundup. Its built-in sport apps cover pool swimming, open-water swimming and triathlon as separate profiles, and the swim metrics go further than Apple’s without requiring a third-party app.
Water resistance is 5 ATM plus with a 10 ATM rating, and the 40 metre depth capability comes with leakproof metal buttons plus scuba and apnea activity support. Metal buttons matter more than they sound: a capacitive touchscreen is miserable to operate with a wet hand or chlorine on the fingertip.
Battery life runs up to 16 days in smartwatch mode and 47 hours in GPS mode, so a full training week never touches the charger. Multi-band GPS with SatIQ, a compass, gyroscope and barometric altimeter handle the open-water track, and there is a built-in speaker and microphone for wrist calls.
Training readiness, real-time stamina and the ECG app sit alongside the swim data, which is what makes this a genuine multisport watch rather than a swim watch that also counts steps.
Swim detail that the Apple watches do not cover
This is where Garmin’s swim heritage shows. The fenix 8 logs pool swim and open water as first-class activities with drill logging, so if your coach asks you to log a set of underwater kick sets or a pull buoy drill, you can record it as a drill rather than as swim time. It also handles multisport transitions for triathlon sessions without you touching the watch mid-session.
The 1.4-inch AMOLED display runs at 1000 nits, which is readable in bright sun but not remarkable next to the Samsung Ultra2’s 5000 nits. There is also a built-in LED flashlight, which sounds trivial until you are walking back from an early swim in winter.
Who the size and complexity rule out
The 47mm stainless steel case is substantial, and the menu system asks more of a new swimmer than an Apple Watch does. Beginners often report a genuine learning curve before the first full swim profile is set up correctly, which is a fair trade to weigh against the depth of data once you are there.
If you only swim laps in a 25 metre pool twice a week, this is far more watch than you need. If you train across pool, open water and multisport, it is the one most likely to stay in your kit bag for a decade.
4. Garmin Forerunner 970: Best for Triathlon and Brick Sessions
Garmin Forerunner® 970, 47mm, Carbon Gray DLC Titanium, Black/Whitestone
Water resistant to 50m
Multisport auto-transition between swim bike and run
15 days in smartwatch mode
Pros
- Built-in triathlon function with auto-transition
- Full-colour built-in maps with multi-band GPS
- 26 hours of GPS and 15 days in smartwatch mode
- Sapphire lens and titanium bezel
Cons
- Steep learning curve compared with simpler watches
- Included silicone band may run long
- Large case for a running watch
If your training is swim then bike then run, the Forerunner 970 handles the whole session on one wrist. Multisport auto-transition detects when you swap sport and records your transitions without you having to edit the activity afterwards, which is the single feature that makes a triathlon watch worth owning.
It is rated to 50 metres with pool and open-water swim profiles, so the swim side is fully covered. The 1.4-inch AMOLED touchscreen runs at 454 by 454 with a titanium bezel and sapphire lens, and owners report no visible scratching after heavy use.
Battery is the standout: up to 15 days in smartwatch mode and 26 hours in GPS mode from a 560 mAh cell. That means a full multisport week including the swim, the bike and the run, and no charging in between.
Full-colour onboard maps across 32 GB of storage and multi-band GPS with dynamic round-trip routing add real value on the bike and run legs, and the built-in speaker and microphone handle wrist calls.
Swimming and multisport specifics
Garmin Coach running and triathlon plans adapt the session to your target event, and the swim profile sits in the same ecosystem as the run profile, so your training load is calculated across all three sports rather than separately. Wrist-based running dynamics cover cadence, stride length, ground contact time and running power, which feeds straight into pacing decisions off the bike.
At 50 metres this is a pool and surface-water rating rather than an underwater instrument. There is no depth capability here, so it is not the watch for underwater training or surfacing deeper than a few metres.
Where it is not the right tool
The learning curve is steep relative to an Apple Watch, and owners frequently report the included silicone band runs long and is not a QuickFit connector, so expect to change the strap early. For a swimmer who never touches a bike computer, most of this watch is dead weight and lighter alternatives cover the swim half of the job perfectly.
It also integrates with Edge bike computers and Wahoo and Zwift trainers, which is a strong argument if you already own that ecosystem.
5. COROS PACE Pro: Best Value with Offline Maps
COROS PACE Pro GPS Sport Watch, 1.3-inch AMOLED Touchscreen – Blue
5ATM with pool and open-water swim modes
1.3-inch always-on AMOLED at 1500 nits
38 hours outdoors
Pros
- 1500-nit always-on AMOLED readable in a bright pool
- 38 hours of outdoor tracking and 20 days of typical use
- 32 GB storage with global offline topographic maps
- Dual-frequency GPS on a new satellite chipset
Cons
- Smartwatch features are secondary to fitness tracking
- Requires a smartphone companion for full functionality
The PACE Pro covers both pool and open-water swimming at 5 ATM, and it does it on a watch that sits well below the premium multisport models. That combination of swim modes, dual-frequency GPS and offline maps is rare at this level.
The 1.3-inch always-on AMOLED at 1500 nits stays visible in a bright pool or under midday sun, and the gesture-activated backlight wakes the screen with a flick of the wrist, which stops you fumbling for buttons while standing at the wall.
Battery life runs to 38 hours of outdoor activity, 31 hours with dual-frequency GPS, 20 days of non-stop use or six days with the always-on display on. A two-hour pool session barely touches that.
The new satellite chipset delivers what owners describe as the most precise GPS in the COROS range, and 32 GB of storage holds global offline topographic maps with turn-by-turn navigation. A two-year warranty is also longer than most of the field.
What swimming data you actually get
Pool and open-water swim modes cover lap counting, distance, pace and stroke detection, and the data lands in the COROS app alongside Training Status, custom workouts and sleep analysis. The 22mm band fits 130 to 220mm wrists, which is a comfortable middle range for most swimmers.
What you do not get is a smartwatch experience. There are no message replies, no voice assistant and no notifications to speak of. This is a training watch that happens to tell you the time, and treating it as a smartwatch is how buyers end up disappointed.
Considerations before you buy
It needs a phone companion for syncing and full functionality, and the app ecosystem is narrower than Garmin’s or Apple’s. The 49g body and USB-C charging with the keychain adapter are practical touches that more expensive watches still lack.
For a swimmer who also runs and cycles on a budget, this is the pick we would make first. For someone who wants their watch to double as a phone screen, look at the Apple Watch Series 11 instead.
6. Garmin Instinct 3 Solar: Best Battery Life for Long Sets
Garmin Instinct® 3 Solar, Rugged GPS Smartwatch, 45mm, Black
10ATM and IPX8
Solar charging lens with up to 28 days battery
0.9-inch transflective MIP display
Pros
- Solar charging lens with unlimited battery in full sun
- 10ATM rating and MIL-STD-810 shock and thermal resistance
- 52g body with interchangeable bands
- Built-in LED flashlight with strobe modes
Cons
- 0.9-inch monochrome MIP display is small and less detailed
- Not a smartwatch app or data ecosystem
- Some features need a paired smartphone
The Instinct 3 Solar is rated to 10 ATM with an IPX8 rating and MIL-STD-810 thermal and shock resistance, so it is built for a hard life around water. Pool and open-water swim profiles are there, and the watch is light at 52g with a fibre-reinforced polymer case and a metal-reinforced bezel.
Battery is the reason to buy it. A solar charging lens gives unlimited battery life in full sun under the manufacturer’s assumption of three hours a day outdoors, and the listed battery life averages up to 28 days. Nobody charges this watch before a swim.
The trade is the display. It is a 0.9-inch transflective memory-in-pixel panel at 176 by 176, which stays readable in bright sunlight without a backlight but shows far less detail than the AMOLED screens elsewhere in this list. You read pace, you do not study a graph at the pool wall.
Multi-band GPS with SatIQ, a three-axis compass and a barometric altimeter come standard, along with wrist heart rate, advanced sleep monitoring and Pulse Ox.
Swim use and controls
Physical buttons are the defining feature here, and they are the reason outdoor swimmers like this watch so much. Wet hands, cold fingers and a slippery pool deck are all situations where a touchscreen fails you and a button does not. The built-in LED flashlight with variable intensity and strobe modes handles the swim-to-dawn-lake-start case.
Garmin Pay and Connect IQ support let you add apps, and incident detection with Assistance can share your live location with emergency contacts if something goes wrong in open water.
Who should choose it
Pick this if battery life is your top priority, you swim outdoors in winter, or you prefer a watch that does a small number of things extremely well. Do not pick it if the app ecosystem and third-party data analysis are part of your appeal, because it is a tool rather than a smartwatch.
The 45mm case sits between a casual watch and a multisport watch, which makes it easier to wear to the pool than the fenix 8 or the Ultra 3.
7. COROS PACE 4: Best Smartwatch for Beginner Swimmers
COROS PACE 4 Ultralight Sport GPS Watch (Black Silicone, Standard)
5ATM with pool and open-water swim tracking
41 hours of GPS
32g body, 11.8mm thin
Pros
- Exceptionally light at 32g
- 41 hours of continuous GPS and up to 19 days of daily use
- Accurate GPS with clean routes and no random jumps
- Strava and Apple Health syncing out of the box
Cons
- Fewer smartwatch features with no message replies
- Heart rate accuracy is spotty during interval efforts
- 1.2-inch screen with glass less tough than sapphire
The PACE 4 is the watch we would hand to someone who has just started swimming. It weighs 32g with the nylon band and is 11.8mm thin, which is light enough that you genuinely forget it is on your wrist for a two-hour beginner session.
Swimming works at 5 ATM with both pool and open-water tracking. Owners switching from a Fitbit report accurate swim and cycling logs, and the digital crown plus two buttons and a touchscreen make it easy to start a workout with wet hands.
Battery life is 41 hours of continuous GPS use and up to 19 days of daily use, so charging is a monthly event rather than a nightly one. GPS accuracy is clean, with breadcrumb mapping, a compass and stored courses with turn-by-turn directions.
The app is fast and syncs cleanly with Strava, Nike Run Club and Apple Health. That last point matters more than it sounds: a beginner logging their first month of sessions wants the swim to show up in the same place as everything else.
Swim metrics for a new swimmer
Pool and open-water swim tracking covers the basics a new swimmer needs: laps, distance, pace and stroke detection, with the session logging to the COROS app for a simple weekly view. The 1.2-inch AMOLED touchscreen has 164% higher resolution than the previous generation and auto-adjusts brightness, so it stays readable at the pool hall window.
Voice recording for training logs and voice control for alarms and custom workouts are unusual at this level. Recovery time, sleep stages, HRV and menstrual cycle tracking round out the health side.
Limits worth knowing before you start
Wrist heart rate accuracy drops during interval efforts, and owners report pace can lag on anything other than easy efforts, so a chest strap is worth adding if you are training seriously. There are no message replies and no voice assistant, which is the trade for the light weight and long battery.
The 1.2-inch screen is small for reviewing detailed graphs, and the glass is not as tough as sapphire. For a first swimming watch, those are acceptable; for a daily training computer, they are not.
8. Amazfit Active Max: Best Multi-Week Endurance on a Budget
Amazfit Active Max Smart Watch, 1.5″ AMOLED Display, GPS, iOS/Android
5ATM and 50m water resistance
1.5-inch AMOLED at 3000 nits
Up to 25 days of battery
Pros
- Up to 25 days of battery life with some owners reporting more than three weeks
- 3000-nit display readable in direct sunlight
- Built-in GPS with five satellite systems
- Works with both iOS and Android
Cons
- App ecosystem less developed than Garmin or Apple
- Advanced health metrics lose accuracy during intense workouts
- Stand and step counts can diverge from a phone
The Active Max is rated 5 ATM and 50 metres for pool and open-water swimming, and owners switching from Apple and Garmin report swim tracking that holds up well, including real open-water distance. For a swimmer who wants both water tracking and a watch that lasts weeks, that combination is unusual.
The 1.5-inch AMOLED runs at 3000 nits, which is among the brightest displays in this group and makes the screen easy to read at poolside in direct sun without you cupping your hand over it.
Battery life is up to 25 days from a 200 mAh cell, with some owners reporting 23 days. Four gigabytes of onboard storage holds downloaded maps and music, and built-in GPS supports BeiDou, GLONASS, GPS and Galileo with free downloadable terrain and ski maps.
There are 170+ workout modes with Zepp Coach AI running plans, Bluetooth calling with a built-in speaker and microphone, and a BioCharge energy score alongside heart rate, SpO2, sleep and stress tracking. It pairs with both iOS and Android phones, which no Apple watch can do.
Swim performance and platform freedom
Swimming is a listed sport type alongside a general pool and open-water swim capability, and the display brightness matters more than it sounds when you are trying to read split times at the end of a length with the sun overhead. The 1.5-inch screen is one of the larger ones here.
Cross-platform support is the quiet advantage. If you use an Android phone, or you switch phones, this watch does not care, and the offline map downloads remove the need to carry your phone on a long open-water swim.
Where to temper expectations
The app ecosystem is less developed than Garmin Connect or the Apple Health stack, and the swim detail is shallower than the fenix 8’s. Owners report that advanced health metrics lose accuracy during intense workouts, and stand and step counts can drift noticeably from a phone.
Screen protectors are hard to source for this model, and one owner reported a rash from the supplied band. Those are small annoyances on a watch whose core appeal is that it disappears and keeps working.
9. Samsung Galaxy Watch Ultra2: Best Underwater Depth Features
Samsung Galaxy Watch Ultra2, Titanium Gray, 47mm LTE Smartwatch
10ATM and IP69K to 100m
EN13319-certified dive computer from Mares
5000-nit display with LTE
Pros
- IP69K dust-tight and 10ATM rated to 100m
- EN13319-certified dive computer with depth limits and safety stops
- 5000-nit display readable in harsh conditions
- LTE cellular connectivity
Cons
- Newer model with a smaller pool of owner feedback
- Designed primarily for Android smartphones
- Large 47mm titanium case
The Galaxy Watch Ultra2 is built as a serious underwater instrument alongside the Apple Watch Ultra 3. It carries IP69K dust-tight protection and a 10 ATM rating, water resistant to 100 metres, and it includes an EN13319-certified dive computer app from Mares with ascent and descent monitoring, depth limit notification and safety stop information.
For a swimmer rather than a diver, that depth capability is mostly reassurance. It means the watch is sealed well beyond what a pool or a surface swim requires.
The 5000-nit display is the standout specification. Pool halls and outdoor open-water swims are bright, and being able to read pace and splits at the wall without shielding the screen is a genuine daily-use benefit.
Built-in LTE means calls and messages work with no phone nearby, and built-in GPS provides path, elevation and pace guidance with hydration alerts. A two-year warranty is longer than most of the field.
Swimming and ecosystem fit
It works with Samsung and other Android phones, and the Vitals app tracks five health metrics while you sleep, which pairs well with swim training load. Raise your wrist and speak naturally for AI assistance with no wake phrase, which is unusually quick when your hands are wet.
The 47mm titanium case is large, closer to the Ultra 3 than to a lifestyle watch, so try it on before committing if you have a smaller wrist.
The catch
This is a newer model with a smaller pool of owner feedback than the established alternatives, and its review count is the second lowest in this roundup. That is not a quality judgement so much a warning: there is less long-term evidence about battery ageing, band durability and swim accuracy after years of use.
If you are on Android and want a watch that could double as a dive computer, it is an unusual and capable option. If you want the deepest pool-swim data instead, the Garmin fenix 8 is the stronger swim specialist.
10. Samsung Galaxy Watch 7 40mm: Best for Samsung Phone Owners
Samsung Galaxy Watch 7 40mm Bluetooth AI Smartwatch w/Energy Score, Wellness Tips, Heart Rate Tracking, Sleep Monitor, Fitness Tracker, 2024, Cream [US Version, 1Yr Manufacturer Warranty]
5ATM plus IP68 rated for pool swim tracking
40mm AMOLED at 2000 nits
Up to 30 hours battery
Pros
- One of the largest review bases here at 7949 ratings
- Thin and lightweight at 5.9 ounces
- Bright AMOLED readable in direct sunlight
- Fast wireless charging and quick pairing
Cons
- Battery life closer to one day despite the 30-hour rating
- Swipe pattern lock can fail to appear
- No built-in GPS in this Bluetooth configuration
The Galaxy Watch 7 in this 40mm Bluetooth configuration is rated 5 ATM plus IP68 for pool swim tracking, with water resistance listed to six feet. That is enough for surface pool swimming, and the Bluetooth version is lighter and smaller than the cellular models.
At 5.9 ounces and 40mm across, it is the smallest watch in this roundup. The AMOLED panel runs at 2000 nits on a 432 by 432 resolution, which is bright enough to read at poolside.
![Samsung Galaxy Watch 7 40mm Bluetooth AI Smartwatch w/Energy Score, Wellness Tips, Heart Rate Tracking, Sleep Monitor, Fitness Tracker, 2024, Cream [US Version, 1Yr Manufacturer Warranty] customer photo 1](https://www.pwice.com/wp-content/uploads/2026/10/B0D1YNVD88_customer_1.jpg)
Battery is listed at up to 30 hours average from a 300 mAh cell, but that is the most repeated complaint among owners, with many reporting closer to a full day. Fast wireless charging helps, though a nightly routine is realistic.
The BioActive sensor brings improved heart rate tracking that filters out body movement, and Galaxy AI adds an Energy Score, Wellness Tips, sleep tracking with moderate-to-severe sleep apnea detection, and comparison of your current run or bike against your last.
![Samsung Galaxy Watch 7 40mm Bluetooth AI Smartwatch w/Energy Score, Wellness Tips, Heart Rate Tracking, Sleep Monitor, Fitness Tracker, 2024, Cream [US Version, 1Yr Manufacturer Warranty] customer photo 2](https://www.pwice.com/wp-content/uploads/2026/10/B0D1YNVD88_customer_2.jpg)
Swim performance and what to check before buying
Pool swim tracking is supported and the data covers laps, distance and pace through the Samsung Health app. There is no open-water GPS in this Bluetooth configuration, so if you swim in a lake or the ocean regularly, you would need the GPS version instead.
Users report a swipe pattern lock that can fail to appear when needed and a screen lock that can re-engage repeatedly, both of which silently interrupt workout recording. That is a swimming-specific problem worth taking seriously, because a dropped recording mid-set is the thing swimmers complain about most.
Who it suits
Choose it if you own a Samsung phone, you swim in a pool rather than open water, and you want health and sleep data as much as swim splits. Its review base is the second largest in this roundup, which means long-term behaviour is well documented.
The 40mm screen is small for reviewing detailed graphs after a session, so if you like to study pace charts rather than glance at them, one of the larger AMOLED watches suits you better.
11. SUUNTO Race: Best for Big Buttons and Offline Colour Maps
SUUNTO Race: GPS Sports Watch, Large & Bright AMOLED Color Screen, Long Battery Life
100m water resistant with swim mode
1.43-inch AMOLED with sapphire lens
Dual-band GNSS
Pros
- 100m water resistance with swimming among supported sports
- Large 49mm colour AMOLED readable underwater
- Up to 40 hours in full tracking and 10 days in daily mode
- Free global offline colour maps with breadcrumb trails
Cons
- Wrist heart rate readings are inconsistent and drift on runs
- Some users report skin irritation from the supplied band
- Menus are haphazard compared with competitors
The SUUNTO Race is water resistant to 100 metres with swimming listed among its supported sport types. For a pool swimmer that rating is more than enough headroom, and the 49mm case with a 1.43-inch colour AMOLED display and sapphire lens is genuinely easy to read while you are moving.
The digital crown for fast browsing is the standout control. It scrolls through data with a physical wheel, which means you never have to swipe a wet screen mid-set, and the same logic applies to starting and stopping a workout.
Dual-band GNSS supports GLONASS, GPS, Galileo and QZSS, and 16 GB of storage holds free global offline colour maps with paths, contour lines, breadcrumb trails, points of interest and bearings. Owners describe good value against equivalent Garmin models.
Battery life runs to 40 hours in the most accurate tracking mode, up to 120 hours in tour mode and up to 10 days in daily mode with continuous heart rate. There is also a barometer for open-water and trail use.
Swimming and multisport use
Sport modes cover running, cycling, multisport and swimming, and the offline colour maps make the open-water side genuinely useful when you are swimming in an unfamiliar lake. The sapphire lens resists damage, which matters in a bag full of pool kit and fins.
At 83g it is one of the larger watches in this roundup, which you notice after the first few hundred lengths.
The two recurring complaints
Wrist heart rate readings are inconsistent and drift significantly on runs according to owners, so take that reading with care in a multisport block. Skin irritation and rashes from the supplied band are also reported, and the watch can slide down the wrist during cycling.
The app is slow to load activities and Find My Phone only works after a manual sync. With the lowest rating in this group, treat it as a watch worth trying on rather than a confident blind buy.
12. Amazfit Bip 6: Best for Low-Cost Pool Tracking
Amazfit Bip 6 Smart Watch, 1.97″ AMOLED Display, GPS, iOS/Android
50m for pool and open-water swimming
1.97-inch AMOLED at 2000 nits
14-day battery
Pros
- Very large 1.97-inch AMOLED for a low-cost watch
- Two-week battery with no nightly charging
- Built-in GPS with downloadable maps
- Lightweight aluminium build comfortable for continuous wear
Cons
- Only 512 MB of storage limits offline maps and music
- Less detailed metrics and app polish than premium sports watches
- Plastic-and-silicone build is less premium in rough pool environments
The Bip 6 is the most affordable route to swim tracking in this roundup and it does the fundamentals: 50 metre water resistance with swimming and pool and open-water swimming listed among its sport types, plus a 1.97-inch AMOLED at 2000 nits that is larger than the screen on most flagship watches.
That screen size is the reason it sells. You can read pace and splits from the wall without leaning in, and the 2000-nit brightness handles a sunlit pool hall.
Battery life runs up to 14 days from a 340 mAh cell, so there is no nightly charging habit to form. Built-in GPS supports BeiDou, GLONASS, GPS and Galileo with free downloadable maps and turn-by-turn directions.
There are 140+ workout modes including AI coaching, and continuous heart rate, blood oxygen, breathing rate and stress monitoring. It pairs with Android 7.0 and later or iOS 14.0 and later.
What pool tracking looks like on this watch
It is bought as an affordable swim-capable tracker, and the swim data lands in the Zepp app with laps, distance, pace and duration. That is enough for a beginner who wants to know whether they are improving week to week without spending serious money or changing any other habit.
Open-water swimming is listed as supported and the built-in GPS will trace a route, but this is single-band hardware with 512 MB of storage, so offline map capacity is limited.
Where expectations need lowering
This watch has the lowest rating in the group at 4.2, with 10% of reviews at one star. The metrics are less detailed and the app experience is less polished than premium sports watches, and the aluminium and silicone build is less premium in a rough pool environment.
Use it as a dedicated pool watch rather than as a daily driver, and pair it with a chest strap if you care about heart rate accuracy. For a first watch that lives in a swim bag, it does a genuinely useful job for very little money.
How to Choose a Smartwatch for Swimming in 2026
The single most important number is the water resistance rating, and most swimmers misread it. Here is what each rating actually means in plain English.
Water resistance decoded: 5ATM, 10ATM and depth ratings
5 ATM (roughly WR50 / 50 metres) means the watch is safe for surface swimming, showering and shallow-water activity. It is not a statement about depth you can dive to. Every watch in this roundup rated 5 ATM, including the Apple Watch Series 11, COROS PACE Pro, PACE 4, Galaxy Watch 7 and Amazfit Active Max, is fine for pool laps and surface open water.
10 ATM (roughly WR100 / 100 metres) adds headroom for high-speed water sports and repeated immersion. The Garmin fenix 8, Instinct 3 Solar, Galaxy Watch Ultra2, Apple Watch Ultra 3 and SUUNTO Race carry this rating, and it is the right choice if you surf, cold-water swim or handle the watch roughly.
A depth rating to 40 metres under EN13319 is a different category entirely. That is what the Apple Watch Ultra 3 and Galaxy Watch Ultra2 carry, alongside the fenix 8’s 40 metre depth capability. It means the watch functions as an underwater instrument, not just a swim logger.
The trap is marketing language. A watch described as waterproof at 5 ATM is still only 5 ATM. IP6X and IPX8 ratings measure dust and water ingress under test conditions, not a permanent guarantee, and chlorine is harder on seals than plain water.
Pool or open water: the features you actually need
For pool swimming, you need pool swim mode with auto-detection, automatic stroke identification, your pool length configurable, and a display readable at the wall. GPS is irrelevant indoors, so do not pay for it if you only ever swim laps.
For open water, GPS becomes the deciding feature. Multi-band or dual-frequency GPS gives a cleaner track when you are swimming past cliffs or buildings, and it matters much more than extra step counting. Corrosion resistance and a rinse-friendly case matter more outdoors than in, because salt water is unkind to seals and metal buttons.
If you do both, the Garmin fenix 8 and Forerunner 970 are the two watches here that treat pool, open water and multisport as first-class equal activities rather than as an afterthought bolted onto a running watch.
Stroke detection, SWOLF and drill logging in plain English
Stroke detection means the watch works out whether you are freestyling, backstroking, breaststroking or butterfly from wrist motion, and counts strokes per length. Auto-detection matters most for beginners, because configuring it once and forgetting it is the difference between usable data and a watch you stop trusting.
SWOLF combines stroke count and stroke length into a single efficiency score. A lower number means you are covering more distance per stroke, so it is the metric that tells you whether your technique is improving rather than just whether you are tired. Most beginners have never seen it, which is why it is worth checking that your watch reports it. Garmin’s fenix line is the clearest source of it here.
Drill logging exists for technique work. If your coach sets a set of underwater kick sets or pull buoy drills, a watch with drill logging can record them as drills, keeping them separate from your main set instead of quietly inflating your distance.
Buttons, battery and phone compatibility
Wet hands break touchscreens. If you swim outdoors in winter, at the lake, or in a pool where you are clipping your fingers rather than wiping them, physical buttons are a genuine safety and usability feature. The Garmin Instinct 3 Solar, Forerunner 970, fenix 8, COROS PACE 4 and SUUNTO Race all give you buttons that work in the water.
Battery decides whether the watch gets used. A 24-hour watch like the Apple Watch Series 11 needs a daily habit; a 25-day watch like the Amazfit Active Max needs none at all. For a two-hour pool session plus an evening run, anything above 20 hours of GPS tracking covers a full day.
Phone compatibility is the deal breaker for many swimmers, and it is worth being blunt about it. Apple watches need an iPhone. The Galaxy Watch Ultra2 works with Samsung and other Android phones. The Amazfit Active Max and Bip 6, and the COROS watches, work with both, which makes them the easiest option if you switch phones or share a household. Our guides to the best smartwatches for Android and the best smartwatches overall cover the platform side in more depth.
If you are choosing for a smaller wrist or a different fit, we have a separate breakdown of the best smartwatches for women, including band sizing and case profile. For outdoor use beyond swimming, the best smartwatches for hiking and outdoor adventures covers the battery and navigation side in detail.
Swim Tracking Accuracy: Where Watches Get It Wrong
Most disappointed swimmers are not using a bad watch. They are using a good watch configured badly, in a pool whose length does not match the setting.
Short-course pools break lap counting
An r/AppleWatchFitness user reported the Apple Watch Ultra 2 undercounting laps and yards by roughly half on a 13-and-two-thirds-yard pool. That is not a failure of the sensor; it is a configuration problem. If your pool length is set to the wrong value, every distance and split after it is wrong too.
Before your first real swim, set the pool length to match your lane count exactly, do a short calibration swim of ten to fifteen lengths so the watch learns your stroke, and then time one length manually to check the watch agrees. Ten minutes of setup removes the single largest source of bad swim data.
Garmin and Apple disagree on single lengths
A live debate on r/Swimming has swimmers comparing Garmin and Apple Watch single-length times over repeated manual timing, and finding the two do not always match. Neither watch is necessarily wrong. Garmin’s swim algorithm and Apple’s differ in how they detect the turn and the wall push-off, and both produce small offsets that compound over a set.
The practical response is to pick one watch and stop cross-checking. Use a manual wall clock or a pace clock to validate occasionally, and treat differences of a second or two per length as noise rather than as a verdict on either brand.
GPS drops out and wrist heart rate drifts
Open-water GPS is the weakest link in most watches. Signal loss happens under bridges, in currents, and in cold water that slows the receiver. The Apple Watch Ultra 3’s dual-frequency GPS and Garmin’s multi-band setup with SatIQ handle the hard cases better, but no watch holds a perfect line through a river bend.
Wrist optical heart rate is less accurate in water than on land because your arm moves, the water is cold and the watch is often loose after thousands of strokes. If heart rate is the number you are training to, a chest strap remains the more accurate option even with a watch as good as the fenix 8.
Rinse after every swim
The cheapest way to extend the life of any of these watches is to rinse it in fresh water, dry it, and take the band off to dry separately. Chlorine and salt attack seals, metal buttons and band materials over time, and a wet silicone band left on the wrist is the commonest cause of skin irritation.
A longtime owner reported water getting into a watch after three years of regular swimming, which ended it. That is not unusual for a watch that was rinsed occasionally rather than after every session, and it is the strongest argument for buying a 10 ATM model if you swim outdoors daily.
Frequently Asked Questions
What is the best smartwatch to track swimming?
The Apple Watch Series 11 is the best smartwatch for tracking swimming. It is water resistant to 50 metres, auto-detects pool versus open water, records stroke type and pace per 100 metres without manual setup, and it carries the largest review base of any watch in our roundup. For open-water swimming where GPS reliability is the deciding factor, the Garmin fenix 8 or the Apple Watch Ultra 3 are stronger choices.
Which smartwatch is better for swimming, Apple Watch or Garmin?
For pool swimming and general health data, Apple is stronger: the Series 11 auto-detects pool and open water, identifies stroke type and syncs everything to a mature health app. For open water, triathlon and technique work, Garmin is stronger: the fenix 8 has multi-band GPS with SatIQ, drill logging, SWOLF scoring and separate pool, open-water and triathlon swim profiles.
Can I swim in a pool with a smartwatch?
Yes, as long as the watch carries at least a 5 ATM rating, which covers surface swimming. Every watch in our roundup meets that standard. Check that pool swim mode exists, set your pool length before your first session, and do a short calibration swim so the watch learns your stroke.
What water resistance rating do I need for swimming?
You need 5 ATM, roughly the same as WR50 or 50 metres, for pool swimming and surface open water. Choose 10 ATM or WR100 if you swim in cold water, surf, cold-water swim or handle the watch roughly. Choose a watch with an EN13319 rating to 40 metres only if you want the watch to work as an underwater depth instrument.
Which smartwatch is better for open water swimming?
The Apple Watch Ultra 3 and the Garmin fenix 8 are the strongest for open water. Both pair a 100 metre rating with multi-band GPS, which keeps a cleaner track past cliffs and buildings. The Samsung Galaxy Watch Ultra2 also offers 100 metre water resistance, an EN13319-certified depth instrument and a 5000-nit display.
Do I need a GPS watch for pool swimming?
No. GPS does nothing indoors, and the pool mode counts lengths using wrist motion instead. GPS only becomes essential for open water, where it traces your actual route and gives you real distance and pace rather than a straight-line estimate.
What is the best swim watch for a beginner?
The COROS PACE 4 is our pick for a beginner. It weighs 32g, runs both pool and open-water swim modes, lasts 41 hours on GPS and up to 19 days in daily use, and syncs to Strava and Apple Health so a new swimmer can see progress in one place.
Final Verdict for Swimmers in 2026
After working through twelve watches, the Apple Watch Series 11 remains the best smartwatch for swimmers. The 50 metre rating covers pool and surface open water, the auto-detection removes setup friction, stroke and pace metrics arrive without a calibration fight, and the review base behind it is the largest we assessed. If you already own an iPhone, nothing else here does more for you per pound spent.
Swim outdoors often and the answer changes to the Apple Watch Ultra 3 for battery and dual-frequency GPS, or the Garmin fenix 8 if you would rather leave the phone at home entirely and want drill logging and SWOLF. Triathletes should look at the Garmin Forerunner 970 for auto-transition across swim, bike and run.
Below that, the COROS PACE Pro is the value pick with offline maps, the Garmin Instinct 3 Solar wins on battery and buttons, the COROS PACE 4 is the right first watch, and the Amazfit Active Max covers both platforms with weeks of battery. At the budget end, the Amazfit Bip 6 does a credible pool session for very little.
Whatever you choose, set the pool length correctly, do a calibration swim, and rinse the watch in fresh water when you get out. Those three habits fix most of the disappoint swimmers report.
