The history of the brand of ZRC watches


ZRC is founded in Geneva, a fruit of a partnership between Edmond Zuccolo and Joseph Rochet.


The company wins Geneva Grand Prix for Innovation in Industry for Creatible Metal Bracelets.


The first ZRC large 300m fund is developed.


After officially approving the first major funds 300 in 1960, the French Navy explained to the designers that the Crown at 3 o'clock was problematic because it was too vulnerable during underwater manipulations. He asked ZRC to "find a solution" to protect the crown without hindering the wrist movements and, above all, to make sure it can not open under water.

The team went on to work and developed the famous crown at 6 o'clock, connected to the housing by an exclusive system consisting of a cannon cut into a single block, making large funds 300 the first and the only watch at Be equipped with a 100% monobloc box watch. In addition, the housing is machined in a molybdenum-reinforced steel type, completely antimagnetic (an absolute necessity for the Mine Clearance group).
The final version of the latter was used by the French Navy from 1964 to 1982 (NATO approved).


ZRC has developed an exclusive retractable lug specific to the inter-horn space, which only allows the passage of the crown or the rotation of the bracelet in the closed position, making it impossible the immersion of the watch if the crown is not completely screwed . The bracelet is also original because of its two extensible links, which allows to wear the watch over a diving combination without any other adjustment. The Ultra-Luminescent Magnum needles provide perfect legibility underwater. Revolutionary watch In many ways, the ZRC large funds was distributed to the firefighters of Paris and the French water ski team. But it was mostly the watch of the French Navy (Toulon Diving School, Third Division of the Toulon Deminer, Commando Hubert) as well as the Italian Navy. As a watch designed by divers for divers, it has also been adopted by non-military units supported by the French Navy, including the famous Calypso of Commander Cousteau, who has shown in the world and has firmly established his reputation.


French Marine

Relevant directly from the central command of the French Marine Office (DCCM) in Paris, the Technical Department of the French Marine Office (STC) was the service at the central command level responsible for carrying out preliminary studies and the approval of the new equipment. It was the "national marine" branch of the French NATO French Codification Bureau (NCO). The Arsenal Shopping Service of Toulon, who had requested the new equipment, had to complete, in accordance with the procedure, an identification form concerning the new ZRC watch it wanted to acquire (trade name of the article, Brief technical description, retail price of the watch). Article, name of the manufacturer, address and code, reason for the purchase, intended use of the marine equipment, etc.). This completed identification form was then sent to the STCM in Paris for review, accompanied by a request for approval of the watch. , with a view to the allocation of a "marine management number" (NGM), which would then allow its treatment.

All watches have therefore undergone a trial period and were tested in all possible conditions of "severe use for military purposes." The MCTS in Paris approved the new equipment and has entered the catalog of the police equipment in assigning him a ship management 13-digit (MGM) Provisional. The watches originally classified under the 6645 surname were then transferred to the group 63, 6355 family).

Strategic Oceanic Force (FOST) created on 1 March 1972 is the component of French underwater nuclear forces born of the will of General de Gaulle to retain nuclear deterrence.

In 2016-17, ZRC has produced a series of 50 ZRC-FOST watches dedicated to the French Navy submariners assets.

An ultimate recognition for ZRC equipping submariners used to maneuver the most technological machine and the most powerful in the world.
In the 60s, the pioneers of Adventure and ZRC develop a beautiful watch that will become a diving icon ... Designed by divers for divers diverse, it was developed by invitation to the French Navy deals closely with the 3rd Mediterranean divers Group. A revolutionary shows in many ways, the Great ZRC Fund 300 will equip the diving school of the French navy, the three demining groups (North Channel, Atlantic and Mediterranean) and the Commando Hubert. Spearheading special forces, this legendary unit is deployed in the greatest secrecy on all continents.

In June 2017 the ZRC and a small group of mine clearance divers organize a Test day to evaluate the operational capacity of ZRC. Mission accomplished for the Great Fund. So these are 175 mine clearance divers and combat divers who will receive their ZRC PLD or NC Special Edition in June 2018 ordered a private subscription. An undeniable proof of the quality ZRC Great Fund 300.
In June 2018, the diving school of St-Mandrier celebrates its 60th anniversary (1958-2018). Founded at the initiative of "Mousquemer" Jacques Yves Cousteau, Philippe Trim and Frédéric Dumas, he stressed the need for the French Navy to develop operational units underwater.

The diving school dates back to 1860 and was founded with the aim to form "mechanics, drivers and deep sea divers." The diving school is responsible for training all divers of the Navy in four disciplines (diver of the Navy, group clearance divers, combat diver, hyperbaric nurse). It also provides training for divers coastguard and the army of the French air and a combat diver training. In addition, it annually hosts several groups of trainees.


The third division of the Group of Toulon clearance divers (GPD III) conducts operations throughout the year to neutralize the historical features (shells, mines, torpedoes, etc.), which are a threat to navigation. He also specializes in work major submarine.

The fully antimagnetic watch ZRC large bottoms and its bracelet (like their dive knives and even diving fin adjustment loops) were very much appreciated by divers, which sometimes had to handle magnetic trigger mines.

& Hubert Commando

Commando Hubert is a naval commando created in December 1947. It is based on the cannier, in the peninsula of Saint-Mandrier. The commando bears the name of Lieutenant Augustin Hubert, killed in battle on June 6, 1944 in Ouistreham.
