All about the ZRC Geneve RUTHENIUM GF42103
Everything about the ZRC Geneve RUTHENIUM GF42103, which impresses with its gray dial.
The Grands Fonds combines comfort and traditional aesthetics with uncompromising technical reliability. This modern version of the original Grands Fonds 300® with its blue dial and rubber strap offers all the advantages of a diving watch.
The features of the ZRC Geneve RUTHENIUM GF42103
With its gray sunburst dial, satin-finished steel case and FKM rubber strap, this model embodies the quintessence of the ZRC Grands Fonds 300® diving watch. The Crown Protection System™ ensures a secure, waterproof closure. The bracelet can only be attached if the crown at 6 o'clock is fully screwed down. The ECS™ system ensures optimal post-dive rinsing and allows the removal of contaminants and salt crystals trapped between the unidirectional rotating bezel with ceramic insert and the case. The hands and date are powered by a reliable Swiss-made self-winding caliber.
INCLUDED IN THE MARINE EQUIPMENT CATALOG
All watches were therefore subjected to a test phase in which they were tested under all possible conditions of military harsh use. The STCM in Paris approves the new devices and includes them in the commissariat's general equipment catalog, assigning them a provisional 13-digit "Numéro de Gestion Marine (MGM)". This temporary number will later be converted into a NATO stock number (NSM). The watches originally classified as deep sea diving watches of the 6645 family were later moved to the group 63, family 6355.)
