The ZRC Grands Fonds combines comfort and traditional aesthetics with uncompromising technical reliability. A contemporary version of the original Grands Fonds 300®, this version with a metal bracelet has all the hallmarks of a diving watch.

With its navy blue/black gradient dial, satin-brushed steel case and metal bracelet, this version represents the quintessence of the Grands Fonds 300 ^® diving watch .
The Crown Protection System™ helps ensure water resistance. The bracelet can only be closed if the crown at 6 o'clock is fully screwed down.
The ECS® system ensures optimal rinsing after diving and eliminates impurities and salt crystals deposited between the unidirectional rotating bezel with ceramic insert and the case.
The hands are orchestrated by a reliable Swiss Made self-winding caliber
