Has a waterproof performance (Water Resistant) Rolex diving table has been widely recognized. For water resistance, the common expression is divided into two kinds, one is the water depth (m), one is the compression value (unit marked: Bar or ATM), the relationship between the depth of each additional 10 M, will increase the equivalent of an atmospheric pressure, namely: 1ATM = 10m waterproof. On the replica watches diving watch waterproof performance, national standards and international standards are clearly defined: all marked waterproof watch, the minimum to withstand 2 atm, that is, 20 meters of water depth without water. 30 meters waterproof that the watch can withstand three atmospheres, and so on.

In this case the watch if it can waterproof, that is qualified.
