What the rating means

ATM is a pressure rating from a lab test. 5ATM is usually described as suitable for swimming in a pool, and 10ATM for more demanding water sport, but each maker states its own limits, and salt water, hot water and soap can matter. IP ratings such as IP68 measure dust and short immersion and are a different scale, so we do not compare them with ATM.

Check before you swim

Read the maker's water statement for your exact model. Check whether the watch has a swim mode, whether the buttons work wet and whether the strap suits the water. Rinse after salt water if the maker advises it. See water resistance ratings and dual-frequency GPS.
