ZRC 1904 Grands Fonds Osmium 41.5mm GF42118

With its blue sunray dial, satin-brushed steel case, and FKM rubber strap, this model embodies the quintessential ZRC Grands Fonds 300^® diving watch.
The Crown Protection System™ provides a secure watertight seal.
Its strap can only be fastened 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, equipped with a ceramic insert, and the case.
The hands and date are driven by a reliable Swiss Made automatic winding caliber.
