ZRC A LONG-STANDING FAMILY HISTORY

ZRC, founded in 1904 by Edmond Zuccolo and Joseph Rochet, has constantly innovated by imagining bracelets and straps and then dive watches. In 1909, when it was established in Geneva, it was issued with No.52 when the Geneva Trade and Companies Register was created.
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.

Soprana has chosen ZRC as a proposal for an unrivaled diving watch.

ADMISSION TO THE NAVY EQUIPMENT CATALOG

All the watches therefore underwent a test period, being trialed in all possible conditions of « military-related harsh use ». Designed by divers for divers it has been developed on call for tenders from the French Navy in close collaboration in the period with the 3rd Group of the Mediterranean divers.
Many improvements have been made over the years, such as the crown at 6 o’clock, the adjustability of the bracelet and the luminescent hands to provide perfect legibility, making the Grands Fonds ZRC a revolutionary watch from many points of view.

BEZEL ECS™ BREVET 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™

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 bracelet, 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.

There is as well a brand new rubber strap compatible for both tongue & butterfly buckles. Inspired by the design of the metal band it is very comfortable and available in many colors.

MOVEMENT SELLITA SW200-1 ELABORATED

The SELLITA movement of the ZRC Grands Fonds 3000 is composed of 26 rubies wheels, on which Incabloc shock protection was used. Extremely precise, the balance performs 28,800 oscillations per hour. With a mechanism diameter of 25.6 mm, it offers a power reserve of 38 hours.

The setting, in the elaborate movement, is 7 sec/day (with an amplitude of 7 sec/day = from 0 to +14 sec/day) which gives extreme precision to the Grands Fonds 300. As a reminder, a COSC certification tolerates -4 sec to + 6 sec/day, an amplitude of 10 sec/day.
