Why is the ruby watch movement?
In watchmaking, rubies are used for various kinds of plywood shaft hole, shock absorbers and escapement fork tile key components, the known as & ldquo; JEWEL” and our country known as & ldquo; drilling & rdquo;.

In order to protect the
The operation of a mechanical watch movement must rely on the transmission power of each gear. Early movement in the escapement wheel rotating shaft, an escapement fork shaft, wheel shaft and gear shaft are screwed into the pores of the brass plate. Axis does not stop the rotation on the copper substrate or cleat, just like the fire by rubbing sticks, friction will wear. The friction, is bound to cause movement of the injury. Splint on a large number of empty even if there is a damaged, leading to block clamping repair can recover the movement's normal work, so maintenance difficulty and cost, it can be imagined.
Until 1700, ruby was found, it has bright color, high hardness, as a table of bearings can greatly reduce friction and damage. So the original purpose of the application of the ruby is not to be beautiful, but to protect the role of the. At the same time, these Ruby bearings can be replaced separately and maintenance, greatly reducing the cost and efficiency of debugging and maintenance...
Is it real?
Initially, which are used in mechanical watch movement of ruby is natural ruby, because the cost is too high, so at that time only high-grade movement. In 1902, the birth of artificial ruby, replaced the natural ruby, is widely used. The main components of synthetic ruby is aluminum oxide, after finishing, high degree of finish, small frictional factor, have a very strong wear resistance, corrosion resistance strong, to improve the movement quality and extend the use life to play a very good role.
The more ruby, the better?
Mechanical watches on the dial often have 19JEWELS, 25JEWELS, 17JEWELS and other words, is a movement in the number of ruby, respectively, said 17 drilling, 19 drilling, 25 drilling, often regarded as one of the specifications of the watch.
Due to the precious stones on the reliability of the watch, the accuracy and service life of the machine is very important, so the number of precious stones is an indicator of quality. General economic table and low table are no stones (more is a pointer type quartz watch) or less precious stones, but it is not more than the gem quality is better, the main is to see whether the movement of the gem is directly related to the quality of the movement.
General basic mechanical watch movement has a 17~19 function, the automatic upper and the movement will increase the 2~4, calendar movement is increased 2... With the complexity of the function of the watch, the number of precious stones will increase, its fundamental purpose is still to play gem high wear resistance and corrosion resistance, in order to guarantee the stability of the movement function and timing accuracy.
