The best swim smartwatch depends on where you swim and what you need it to track. For pool-focused training, Garmin Swim 2 is the most directly swim-oriented choice here. For swimming alongside other sports, consider Garmin Forerunner 965. Apple Watch Series 12 covers pool and open-water workouts as a general smartwatch, while Apple Watch Ultra 4 is the option in this group with stated support for more demanding water activities, including recreational diving within Apple’s limits.
These are manufacturer-supported feature matches, not an accuracy ranking: the available specifications do not establish which watch records swims most accurately in real-world conditions.
Choose by where and how you swim
- Pool training: Look for lengths, distance, pace, stroke detection, rest or set handling, SWOLF, and custom workouts. Garmin Swim 2 and both Apple models list pool-specific features.
- Open water: Confirm that the watch has a dedicated open-water workout. Garmin says Swim 2 records GPS in lakes, oceans, and rivers; Apple lists separate open-water workouts for Series 12 and Ultra 4.
- Swimming plus other sports: Garmin Forerunner 965 is the multisport-oriented option in this group. Its broader capabilities do not prove better swim tracking.
- Water sports beyond swimming: Check the exact model’s activity and depth guidance. A water-resistance rating alone does not establish that a watch is suitable for diving or fast-moving water.
Compare the four watches
| Watch | Best fit | Swimming features supported by the manufacturer | Water-use guidance |
|---|---|---|---|
| Garmin Swim 2 | Swim-focused pool and open-water training | Pool and open-water modes; distance, pace, stroke count, SWOLF, wrist-based heart rate, drill logging, auto rest, pacing alerts, and custom pool workouts. | Garmin lists a 5 ATM water rating. |
| Garmin Forerunner 965 | Swimming as part of broader multisport training | Garmin’s product materials list pool and open-water swimming profiles; its comparison page includes mapping, music, display, and battery attributes alongside Swim 2. | Garmin’s comparison lists a 5 ATM rating. |
| Apple Watch Series 12 | Swim tracking in a general-purpose smartwatch | Pool and open-water workouts, custom pool workouts, splits and auto sets, SWOLF, automatic stroke and kickboard detection, average pace, distance, and laps. | Apple lists 50-meter water resistance under ISO 22810:2010; its guidance limits standard Series models to shallow-water swimming. |
| Apple Watch Ultra 4 | Swim tracking plus specified higher-demand water activities | Pool and open-water workout views, custom pool workouts with haptic interval cues, splits and auto sets, SWOLF, stroke and kickboard detection, water temperature, pace, distance, heart rate, and laps. | Apple lists 100-meter water resistance under ISO 22810:2010 and recreational diving to 40 meters, subject to its activity guidance. |
Which Garmin makes more sense for swim training?
Garmin Swim 2: prioritize swim-specific tools
Swim 2 is the clearest fit if swimming is the main reason you want a watch. Garmin describes pool metrics and open-water GPS, along with training details such as drill logging, auto rest, pacing alerts, and custom pool workouts. Its product information is available on Garmin’s Swim 2 page.

Battery estimates depend on the regional page and operating mode. Garmin’s UK page lists up to 7 days in smartwatch mode, up to 13 hours in GPS with optical heart rate, and up to 72 hours in pool mode with optical heart rate. Garmin Singapore lists up to 7 days, 12 hours, and 2.5 days, respectively, for those modes. These are manufacturer estimates, not guaranteed runtimes; check the figures for the region and configuration you would buy.

Forerunner 965: consider the rest of your training
Choose a broader multisport watch if mapping, music, or a wider set of sports matter alongside swimming. Garmin’s comparison shows the Forerunner 965 alongside Swim 2 and includes differences in display, mapping, and smartwatch-mode battery estimates. It also lists pool and open-water swim profiles. Those broader features are a reason to compare the watches, not evidence that the Forerunner is a more accurate swim tracker. See Garmin’s Swim 2 and Forerunner 965 comparison.
When an Apple Watch is the better fit
Series 12: swimming within a general smartwatch
Series 12 lists separate pool and open-water workouts, with pool tools including splits and auto sets, SWOLF, stroke detection, and kickboard detection. Apple’s Series 12 technical specifications list 50-meter water resistance under ISO 22810:2010. That rating should be read alongside Apple’s activity guidance: standard Series models are for shallow-water swimming, not diving or high-velocity water sports.

These figures do not remove the need to follow the model’s instructions and activity limits. Review Apple’s Ultra 4 specifications before using it for a water activity beyond swimming.

Understand water ratings and activity limits
Apple states, “Your Apple Watch is water resistant, but not waterproof.” Its guidance says Series 2 and later can be used for shallow-water swimming in pools or the ocean; models other than Ultra should not be used for diving, water skiing, or activities involving submersion below shallow depth or high-velocity water. Apple lists Ultra models for high-speed water sports and recreational scuba diving within stated limits. Read Apple’s water-resistance guidance for the applicable model.

Water resistance can diminish over time, and some bands are not water resistant. Verify the documentation for the exact watch and band rather than assuming every configuration in a product family is suitable. A rating is not a substitute for the manufacturer’s operating instructions.

- Training tools: Match the listed metrics and workout guidance to how you train, such as SWOLF, stroke detection, rest handling, or custom intervals.
- Activity limits: Check the manufacturer’s instructions for diving, high-speed water, and other activities beyond ordinary swimming.
