CROWN & METAL BAND

100% safety is guaranteed thanks to this exclusive strap system using retractable lugs. It is now impossible to place the watch in water without screwing the crown back into its original position. If the crown is not screwed down, the strap cannot be correctly repositioned. This effective method prevents oversights that can lead to technical difficulties.

The new Grands Fonds 300^® is equipped with an automatic adjustable bracelet, which allows it to be worn over a diving suit. This unique embedded spring system automatically adapts to the diameter of the wearer’s wrist for unparalleled comfort. No adjustments are required, as two links on either side of the case extend to accommodate the new diameter.

The unique and exclusive clasp of the ZRC^® Grands Fonds offers a non-return system and a 360° lock allowing maximum security. Developed to meet the needs of the Mine Clearance Group of the French Navy it benefits from a careful execution.
