What does 3 atm mean on a watch?

30m, 3 atm = Splash resistant. Ok for rain, hand washing, other occasional contact with water. 50m, 5 atm = Suitable for swimming, fishing, other outdoor activities. 100m, 10 atm = Suitable for snorkeling and other prolonged contact with water, but not for scuba.

Is a 3 ATM Watch waterproof?

In the watch industry, the term “water resistant” refers to the watch’s ability to withstand water pressure. Stated in units of pressure such as atmospheres (ATMs), or depth such as meters, water resistance levels typically range from 3 ATM (30 meters) to 20 ATM (200 meters) and diver’s watches at 200+ meters.

How do you waterproof a watch?

There are several features that make a watch water-resistant. The most important is the gaskets, or “0-rings” – usually made of rubber, nylon or Teflon, which form watertight seals at the joints where the crystal, case back, and crown meet the watch case.
