ZRC 1904 Grands Fonds Iridium 41.5mm GF42183

The ZRC Grands Fonds combines comfort and traditional aesthetics with uncompromising technical reliability. With the contemporary look of the original Grands Fonds 300®, this variant equipped with a metal bracelet carries all the attributes of a diver's watch.

With its iridescent green dial, satin-finished steel case, and metal bracelet, this model embodies the quintessence of the ZRC^® Grands Fonds 300 diver's watch.
The "Crown Protection System" provides a secure watertight seal.
Its bracelet can only be secured if the crown at 6 o'clock is fully screwed down.
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 automatic winding caliber.
