Style and performance distinguish this diver’s watch. The dial, bezel, and wristband of the Grands Fonds 300® “Black Phantom” are clad in black for maximum contrast and legibility. The Super-Luminova® coated markers and hands stand out perfectly against the monochrome backdrop. As with all ZRC® watches, this model features the ECS® system that ensures ideal rinsing after a dive. The Crown Protection System™ provides a secure watertight seal. Its wristband can only be fastened if the crown is fully screwed down. Its Swiss Made automatic caliber guarantees its reliability.

Programmed deformation of materials
ZRC® has a strong expertise in the field of the strains studies linked to the programmed deformation of materials, which guarantees the manufacture of waterproof watches at very great depth (1000M) without resorting to an helium valve or the presence of gel in the case: In addition, it also reduces the thickness of the case making the watch more comfortable to wear. Indeed, sapphire crystal, steel and/or titanium cases and ceramics do not react in the same way to pressure and temperature variations.

BEZEL
ECS® Patent n°1462496 (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 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.

NATO strap
The new Black Phantom DLC 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 thanks to its multiple sizes S, SM, M, L.
