- Hairspring -
A hairspring or balance spring as it is sometimes known is a vital part of a watch’s balance wheel. The oscillation system located in a mechanical watch relies heavily on this part. The hairspring expands and contracts a number of times each second. By doing this, it keeps the inside components of a watch running smoothly and also provides power to the oscillation system. This component is usually made of things like metalloid silicon or even Nivarox alloy.
- Helium Escape Valve -
When submerged in water, a watch can be put under a lot of pressure. The helium escape valve is designed to protect a watch from this type of damage. This valve works to equalize the pressure that can occur when bringing a submerged watch back to the water’s surface. These valves can work automatically or manually, if needed.
