With a taste for extremes, but with moderate risks, the uniqueness of the Diving in Arms missions lies in trust. The interventions of the Demining Divers and Combat Swimmers, guardians of liberties, require an accurate and safe timepiece.

In the 1960s and 1970s, the pioneers of this adventure developed an exclusive diver’s watch with the Geneva-based firm Zuccolo Rochet & Cie. A real success because it was designed “by divers for divers”. A revolutionary watch in many respects, the ZRC Grands Fonds 300 watch will equip the Navy Diving School, its three groups of demining divers (Manche-Mer du Nord, Atlantique and Méditerranée) and the Hubert Commando from 1964 to 1978.
