Hello my fellow watch enthusiasts! If you ever wondered what a pressure test (water resistance test) looks like. Here's an example of one. The machine is basically a small pressure chamber, if the pressure inside the chamber is stable it means no air can enter into the watch case. If no air can enter also no water can enter 😉
