Shock resistant watches
All the self-respecting Swiss brands provide great shock resistance of their watches. Nowadays, the shock resistant properties are actually the base option that is offered for the customers not only in haute horlogerie segment, but also even in medium and low segments.
Let’s try to understand what is the shock resistance of the watch and what kind of guarantee can be offered by the manufacturer. A pioneer in the issue of shock resistance is a legendary Abraham-Louis Breguet. The fact is that one of the most delicate and vulnerable components in all types of mechanical watches are the balance axles. Resourceful Breguet had developed a device that protects the axles against the physical influence. The unpatented invention of Breguet had been picked up by the leading watch manufacturers.
Due to the arising popularity of the wristwatches, the issue of their resistance to the mechanical stress has become more important.
So, what is this shock resistance? Logically, shock resistant watch is a watch that can carry external physical effects in the form of strokes, falls and pressure. The ISO 1413 Horology is the accepted standard in determination of the shock resistance of the watches. According to the ISO 1413 the watch must stand a pressure of 5 kilojoules. However, this standard does not apply to the preservation of the original appearance of the watch, after such pressure.
First, let’s consider the protection of the mechanism. Returning to the question of existing kinds of shock resistance systems, we can remember the watch company Universal Escapement Ltd. This company in the 1933had received a patent for anti-shock device. The invention was called Incabloc. Such devices as Incabloc, Incabloc + and Novodiac are widely used by leading Swiss watch brands.
The anti-shock mechanism Incabloc is known for its accuracy and it is fundamentally different from all existing analogues. This system is mainly used in the ETA caliber watches. ETA has its own anti-shock system Etachoc, which is based on the three-point staple.
World giant Rolex has invested in its own development of Kif Parachoc mechanism, this is a shock resistant system based on the three-point staple. However, Rolex uses higher quality materials and more precise adjustment of the mechanism and because of that the shock resistance is much better.
Seiko, Casio and Citizen and created Diashock, Shokresist and Parashock all that brands as well have their own shock resistance mechanisms.
As for the external protection of the watch, there are much less developments in this field. The quality of the case and the final coating will also affect the degree of shock resistance. A solid case is better protected and less susceptible to any deformation. The desirable case coating is a rhodium, or PVD, the watch with such a coating is quite difficult to scratch.
