Rolex Datejust Replica: A Special Focus
We've all heard of a diver's watch that has a Helium escape valve. Most people are unaware of what this small feature is. It's usually located at 9 o’clock (or sometimes 10 o’clock) on the dial.
First, we must know that the helium molecules are extremely small.Rolex Datejust Replica In the right conditions (such as high pressure), helium molecules can slip past watch seals, unlike water molecules or other molecules that make up air.
The external pressure causes a buildup of helium until the pressure is relieved. If the helium cannot escape, pressure will continue to build up inside the watch and the crystal can be blown out.Omega Aqua Terra Replica Watches This little explosion will blow your eye out. A helium escape vent automatically depressurises a watch when the pressure returns to sea level. The valve is one-way, so it only allows pressure to leave the watch. The valve is designed to prevent water molecules from entering the watch.
