ZRC EXPERTISE

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 (1000M) 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.

BEZEL
ECS™ Patent n°1462496 (Easy Clean System)
The ECS™ is a technical solution to an issue encountered by the mine clearance divers of the Marine Nationale during their many dives: salt crystallizing in the gaps between the bezel and case, thus impeding its rotation. For the 2015 re-issue of the Grands Fonds 300, ZRC has developed and patented a functional solution – the ECS™ was born. A unique system for cleaning the inside of the bezel by circulating fresh water that dilutes and evacuates the sea salt. The ECS™ is the ultimate tribute to the original Grands Fonds and is perfectly in tune with the brand’s identity.

Crown Protection System™
The exclusive ZRC Metal band
100% safety is guaranteed thanks to this exclusive strap system using retractable lugs. It is now impossible to place the watch in water without screwing the crown back into its original position. If the crown is not screwed down, the strap cannot be correctly repositioned. This effective method prevents oversights that can lead to technical difficulties.

The exclusive ZRC Metal band
The new Grands Fonds 300 is equipped with an automatic adjustable strap, which allows it to be worn over a diving suit. This unique embedded spring system automatically adapts to the diameter of the wearer’s wrist for unparalleled comfort. No adjustments are required, as two links on either side of the case extend to accommodate the new diameter.
