ZRC 1904 Grands Fonds Ruthenium 41.5mm GF42103

With its sunray gray dial, satin-finished steel case and FKM rubber strap, this model embodies the quintessential ZRC Grands Fonds 300^® diving watch.
The Crown Protection System™ provides a secure waterproof seal.
Its bracelet can only be attached if the crown at 6 o'clock is fully screwed in.
Its ECS.^® system ensures optimal rinsing after a dive, allowing the removal of impurities and salt crystals lodged between the unidirectional rotating bezel with a ceramic insert and the case.
The hands and date are driven by a reliable Swiss Made self-winding caliber.
