The features of the ZRC Geneve OSMIUM GF42118

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

INCLUSION IN THE NAVY'S EQUIPMENT CATALOG

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