What the clock uses stones
Effective operation of the clock mechanism is directly related to the number of stones. Experienced watchmakers will reveal a secret to you: stones can significantly reduce harmful friction between individual parts of the clock mechanism.
The more stones in hours, the higher their resistance to wear. This claim was even reflected in standards adopted at one time in Switzerland.
The first mechanical clock, which used rubies, was made in the early 18th century. English watchmaker Grey was one of the first to think about how to reduce the coefficient of friction between parts of the clock mechanism. During his life, this master made several thousand watches. And every one used rubies.
However, in modern quality clocks, stones are not used only for the sake of reducing friction. Modern materials, which make the details of the watch, have high characteristics, and therefore are able to compete with rubies in eliminating harmful effects. Why do stones remain a necessary element of the construction of the clock mechanism?
Secrets of clockstones
The fact is that the caffes of the axes of the mechanical clock have a very small diameter. Stones can reduce pressure on parts and keep support elements intact. In addition, stones do not suffer from corrosion characteristic of metals, so the polished surface of artificial ruby retains its working properties much longer.
It is the artificial ruby that is best suited for clock mechanisms. This stone is resistant to wear, has considerable hardness, easy to grind and polish.
The use of rubies guarantees the smooth operation of the mechanism for a long time without any deformation.
What number of stones in a watch is considered optimal? This directly depends on the complexity of the mechanism driving the arrows into motion. For example, in modern clocks of electron-mechanical type, which have additional functions, is used from fifteen or more stones.
It should be remembered, however, that in pursuit of prestige individual manufacturers use an unnecessarily large number of stones in the construction of watches, which is not really caused by a valid necessity. This gives you the opportunity to proudly declare that this watch is of excellent quality. If you do not want to overpay for such a dubious advantage, you should remember that the total number of stones in a quality watch must exactly correspond to the number of axes used in the mechanism.
