Do you know the helium escape valve?

During the deep dive of the watch, as the water pressure increases, there are more helium molecules in the water than under the water molecules, and the tiny helium molecules will squeeze into the case from the gap of the watch under the action of strong pressure. At this time, the pressure in the case gradually increases, and the internal and external pressures are basically balanced. In this way, the watch can be well waterproofed in the deep sea and prevent the case from being broken and deformed.
