Best swim watch for open-water swimming :Garmin Swim 2 Watch

Basically everything the swim nerd needs to break down their swimming workout to find room for improvement.

The original Garmin Swim was only capable of tracking pool and open water swims, but with the updated Garmin 2, it’s become more of a multisport watch, able to track a wide variety of sports and activities out of the water.

It now tracks ALL of the stuff you’d expect from a smartwatch, including sleep, steps, a Body Battery feature that gives you a snapshot of how gassed you are based on the day’s activities, and constant heart rate monitoring.

The Garmin Swim 2 also pairs with Garmin’s connectivity app, which allows you to download custom watch faces, apps, and more.

The Garmin Swim 2 holds a charge for around ~3 days, significantly longer compared to an Apple Watch, and its unparalleled GPS accuracy, and full array of data the watch logs make it one of my favorite swim watches of all time.
