ZRC 1904 Grands Fonds MN64™ RUTHENIUM™

With its sunray gray dial, satin-finished steel case, and FKM rubber strap, this version represents the quintessence of the Grands Fonds 300® diver's watch. Its Crown Protection System™ helps ensure its water resistance. Its strap can only be closed if the crown at 6 o'clock is perfectly screwed down. Its ECS® system ensures optimal rinsing after a dive and eliminates impurities and salt crystals lodged between the unidirectional rotating bezel with its ceramic insert and the case. Its hands are orchestrated by a reliable Swiss-made self-winding caliber. Diameter: 41.5 Available at 28 rue Madame Ref: GF42103
