Water resistance watch test with pressure tester

In this video tutorial, we'll cover how to properly test the water resistance rating of your watch using a water pressure tester. This is useful if you want to verify the WR rating of your watch before taking it to some water activities, or simply to check the waterproof capacity of a watch that has been sitting idle for quite some time.

The method used in this video is a “wet test”, and is useful in revealing the exact location of water intrusion. It is generally safe as long as you follow the guide carefully.
