The inscription “water-resistant” leads many watch owners to assume that their timepiece is completely watertight. A complete watch water tightness is basically possible-nevertheless one should not be misled by the small inscription. In the worst case this ends with a broken watch. At high water pressure or a long time in the water, the apparent water-tight clock leaks.How much water your watch can withstand is explained below.
How Is The Watertightness Determined?
The watertightness of a watch is determined in a test method, which is defined by DIN standard 8310. According to this standard, a wristwatch is considered to be waterproof if it passes the test successfully when it is new. Important to know: In this test method, a static pressure is applied that allows conclusions to be drawn about the bar loadability of a watch.However, if one really gets underwater with his watch, the pressure rises both by movements in the water and under a water jet. The affected clock is burdened at this time much more heavily than was simulated during laboratory tests.
How Watertight Is My Watch Really?
In the following table you will find a list of different tested measurements and the corresponding meter data with which the individual clocks may subsequently be labeled. It also lists what this actually means for everyday use. For example, time knives with a water resistance of 10 atm (100 meters) should be used for water sports and above 20 atm (200 meters) for diving. However, it should be noted that these are merely indicative and not general.
