I have used Garmin swim2 watch for almost a year. I normally in a day swim for an hour or 2 or about 5 to 7 miles/ week. So far no issues at all. Battery might run out quicker if you connect your phone to it and you always receive a lot of emails, calls or messages through the day.

This is the best watch I ever purchased. I have used a Charge 5 (a Fitbit) to swim with in the past, but they are not chlorine-proof, so they eventually died. I like Garmin better for swimming activities.

Compared this to the i watches and this is hands and feet superior in function and looks. Exceptional swim features, but great for other sports as well.

Great purchase! Bought this to replace my vivoactive3 music. Definitely pleased, easy to use, smaller face, comfy band.

love the heart rate monitor. hard to learn how to use, wish it came with a paper manual.
