BEZEL

ECS™ Patent pending (Easy Clean System)


The ECS™ is a technical solution to an issue encountered by the mine clearance divers of the Marine Nationale during their many dives: salt crystallizing in the gaps between the bezel and case, thus impeding its rotation. For the 2015 re-issue of the Grands Fonds 300, ZRC has developed and patented a functional solution – the ECS™ was born. A unique system for cleaning the inside of the bezel by circulating fresh water that dilutes and evacuates the sea salt. The ECS™ is the ultimate tribute to the original Grands Fonds and is perfectly in tune with the brand’s identity.

CROWN

Crown Protection System™


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.

STRAP

Nato strap


The new Grands Fonds 300 is equipped with an exclusive 2 pieces NATO strap, which allows it to be worn over a diving suit. This unique embedded NATO configuration automatically adapts to the diameter of the wearer’s wrist for unparalleled comfort. No further adjustment is required, it accommodates to any diameter since existing in 3 sizes, S-M & L.
