To some, it may seem like it is a waste to use precious stones inside a watch. However, many are unaware that the gems used are generally synthetic rubies harvested and engineered specifically for this purpose. The main purpose of these gems is for watch movement components and friction resistant bearings.
Some of the reasons why stones are used inside a watch is because they are:
- Resistant to wear
- Stable in various temperatures
- Without decay
- Hard to break
The synthetic rubies are created by a formula composed of aluminum and chromium oxide. The engineering consists of a crystallizing process that is comprised of a series of heating, fusing and cooling technology. These stones are generally mass produced and therefore not considered to be in the same valuable category as a "precious gem".
These stones are added to many different styles and types of watches. The total amount of stones found inside the timepiece can vary, as it is specific to the mechanical movements and complexity of the piece. The best rule of thumb: the more that the insides move, the more rubies will be used. A typical fully-jeweled piece contains approximately 17 gems, however others can contain many more than that.
