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 next time you see an account of a watch rated to 100, 200 or even 300 meters failing at lesser depths, pay attention to whether the watch is an ISO 6425 diver or an ISO 2281 water-resistant model. Finally, the ISO standards include an optional test for air-tightness at an overpressure.
