The features of the ZRC Geneve RÉÉDITION GF42215

With its brown dial, satin-finished steel case, and metal bracelet, this model embodies the quintessence of the ZRC Grands Fonds 300® dive watch. The Crown Protection System™ ensures a secure, watertight seal. The strap can only be fastened when the crown at 6 o'clock is fully screwed down. The ECS™ system ensures optimal rinsing after diving, allowing for the removal of impurities and salt crystals that have accumulated between the unidirectional rotating bezel with ceramic insert and the case. The hands and date are powered by a reliable Swiss-made automatic movement.

1964

After the official approval of the first Grands Fonds 300® in 1960, the French Navy informed the designers that the crown at 3 o'clock posed a problem, as it was too vulnerable to manipulation underwater. They asked ZRC® to find a solution“ to protect the crown without hindering wrist movement, and above all, to ensure that it could not open underwater. The team got to work and developed the famous crown at 6 o'clock, connected to the case by an exclusive system consisting of a cannon cut from a single block. This makes the Grands Fonds 300® the first and only watch with a 100% monobloc case. Furthermore, the case is made of a special steel, reinforced with molybdenum, which is completely antimagnetic (an absolute necessity for the Mine Clearance Divers' Group).
