Programmed deformation of materials

ZRC^® has a strong expertise in the field of the strains studies linked to the programmed deformation of materials, which guarantees the manufacture of waterproof watches at very great depth (5100M) without resorting to an helium valve or the presence of gel in the case: In addition, it also reduces the thickness of the case making the watch more comfortable to wear. Indeed, sapphire crystal, steel and/or titanium cases and ceramics do not react in the same way to pressure and temperature variations. This recognized expertise allows the brand to offer reliable, simple and effective watches.

Borrowed from the submarine airlock closing technique the case back of the ZRC^® watches is composed of 2 distinct parts. A clamping ring puts pressure on the shielded back which therefore applies a vertical pressure on the gasket. Therefore the armored back remains «free» and will accompany the ambient pressure that it relays on the joint in order to balance the pressures without ever soliciting the case: By accepting the pressure the case does not twist and therefore cannot take water. This is what allows ZRC^® to offer watches of such reliability with such thin cases.
