The features of the ZRC Geneve IRIDIUM GF42183

With its green sunburst dial, satin-finished steel case, and metal bracelet, this model embodies the quintessential ZRC Grands Fonds 300® dive watch. The Crown Protection System™ ensures a secure, watertight seal. The strap can only be attached if 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 caliber.

INCLUSION IN THE NAVY'S EQUIPMENT CATALOG

All watches therefore underwent a testing phase, during which they were tested under all possible conditions of "militarily rough use". The STCM in Paris approves the new equipment and includes it in the general equipment catalog of the Commissariat, assigning it a provisional 13-digit "Numéro de Gestion Marine (MGM)". This provisional number is later converted into a NATO Stock Number (NSN). The watches, originally classified as deep-sea diver's watches of family 6645, were later moved to group 63, family 6355.)
