Water Resistant vs. Waterproof. No watch is completely waterproof. Most mechanical watches have water-resistance ratings that prescribe a maximum immersion depth. This depth is measured in feet, meters or atmospheres (ATM), where one ATM is approximately 33 feet or 10 meters.
The ATM is just another way to indicate the water resistance of a watch. I ATM is equivalent to roughly 10 meters. A watch that is rated to 10 ATM is good to a depth of 100 meters , which is approximately 330 feet. Its easy to forget that at sea level you are already at 1 ATM.
