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.
What is the power reserve indicator?

Nowadays, the power reserve is undoubtedly one of the hallmarks of the watchmaker’s craftsmanship, just like the tourbillon. There are two main criteria for evaluating the power reserve in the watch industry, let's take a look
