How to Choose
Understand the rating
IP ratings cover splashes and dust. ATM ratings describe pressure and suit swimming better. Check the exact rating.
Care after water
Rinse after salt water and dry the watch. Do not press buttons underwater unless the maker says it is safe.
Ratings and brands
Ratings come from Amazon shoppers and can change. Lesser-known brands can be good value, but check warranty terms, return policy, app reviews and update support, and remember that listing titles are written by the seller.
How We Chose These Products
We searched Amazon for waterproof smartwatches, kept results with a full product name and a rating of 4 or higher, and limited the list to one product per brand so that the choices differ. We did not test the products. See how we pick products.
Common Mistakes to Avoid
- Buying without checking phone compatibility.
