After extensive evaluation, the Wareable team has reaffirmed the Apple Watch Ultra 2 as the leading waterproof smartwatch. Its advanced diving features, auto-depth tracking, and robust app ecosystem make it the top choice for aquatic enthusiasts. However, its premium price may not suit all budgets, prompting experts to test alternatives for swimmers and divers.
Understanding Water Resistance Ratings
For swimming and diving, a smartwatch should have at least a 5ATM and IPX8 rating. These certifications ensure protection against continuous immersion and water pressure. While a 3ATM watch is technically water-resistant up to 30 meters, it isn’t suitable for swimming.
Top Contenders in Waterproof Smartwatches
Apple Watch Ultra 2
The Apple Watch Ultra 2 stands out with a 100ATM rating and EN13319 certification, making it ideal for diving up to 40 meters. Its Oceanic+ app integration enhances diving metrics, while the Ocean strap provides a secure fit.
Despite its 49mm case being bulky for some, the Ultra 2 excels in battery life and outdoor functionality.
Apple Watch Series 10
A more affordable alternative, the Series 10 offers pool and open-water tracking, stroke detection, and Oceanic+ compatibility (though not for deep dives). Its always-on display ensures easy monitoring during workouts.
Garmin Forerunner Series (965, 265, 165)
These models provide consistent swimming metrics, including stroke count, SWOLF scores, and triathlon tracking. The Forerunner 965 leads in battery life, lasting up to two weeks.
Huawei Watch Fit 3
A budget-friendly option, the Watch Fit 3 tracks laps, strokes, and SWOLF, syncing data to Strava. However, its HarmonyOS limits third-party app support.
Huawei Watch 4 Pro
With EN13319 certification, this model supports free diving up to 30m and offers detailed dive metrics. Its titanium-ceramic build and AMOLED display justify its premium price.
Garmin Venu 3
A wellness-focused smartwatch, the Venu 3 excels in stroke detection, SWOLF tracking, and underwater heart rate monitoring.
Amazfit Active 2
An affordable pick, the Active 2 provides basic swimming metrics and Strava integration, though it lacks advanced smart features.
Samsung Galaxy Watch 7
Running Wear OS 5, the Galaxy Watch 7 offers solid swimming metrics and Google Play Store access. However, it’s Android-only, excluding iPhone users.
Final Verdict
While the Apple Watch Ultra 2 remains the best overall waterproof smartwatch, alternatives like the Garmin Forerunner and Huawei Watch 4 Pro cater to different budgets and needs. Swimmers should prioritize 5ATM+ ratings and stroke detection for optimal performance.
