Waterproof function, a qualified watch must be sealed and can withstand 3 atmospheres of pressure.Waterproof watches will be marked on the case back: WATERRESISTANT. There is usually a waterproof level, and those under 10 atmospheres are considered waterproof for life. There are several ways to identify :(1) water depth, such as 30M, (2) pressure: written as 3ATM or 3BAR. Deep diving pressure-resistant watches can be seen up to 600 meters. Many watches are blindly marked with water resistance and cannot be trusted.
