How deep can you really dive with a dive watch? We are going to use our deep sea / pressure chamber and test two diver's watch for their maximum depth / pressure! Our deep sea chamber goes all the way to 300 bars that equals 3 kilometers or 2 miles of depth so we can simulate conditions on bottom of the ocean in this experiment. And after the test we have watch maker to open the watches and have a look what stop the movements of mechanical watch.
