How deep can you really dive with cheap dive watch from Amazon? 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.
