Surface swimming — but keep it out of the shower. We list 16 watches rated 50m. 12 are mechanical (10 automatic, 2 hand-wound) and 4 run on a battery or light. 10 have a sapphire crystal. Cases run from 37mm to 43.5mm.

What 50m water resistance actually means

5 bar of static pressure (ISO 22810). Fine for surface swimming, but not for diving in, jumping, or water sports — impact and movement spike the pressure far past the rated figure. Showering is harder on the seals than cold-water swimming at the same rating: hot water expands metal and rubber at different rates, and soap degrades the gaskets that do the sealing. The rating is a lab measurement, not a depth you can descend to.

Water resistance is not permanent — gaskets compress and age. Manufacturers generally recommend a pressure re-test if the case has been opened, or periodically for a watch used in water.
