I researched all the smart watches that SAID they worked underwater, counted laps, and tracked swimming sessions (in addition to washing dishes, doing laundry, etc LOL). I'm a POOL swimmer and I'm SO GLAD I settled on this dedicated watch, which I take off only to charge every couple of days. It connects seamlessly with the Garmin Connect app & gives me not only a breakdown of my daily lap swims--strokes per minute, per length, stroke efficiency, heart rate and zone, pace, personal best times (I'm not competitive but it's fun to track improvement).Its accuracy in counting laps isn't PERFECT but CLOSE TO IT. The lap counter is triggered by your push-off from the side of the pool (not sure how it works for open swim). I didn't think I'd use the heart rate and stress monitors, let alone the sleep tracker, but that all info has made me more health-minded overall. LOVE LOVE LOVE my Swim 2 watch (:
