Here is a like new Crepas Decomaster Professional 4000M watch with a desirable mesh bracelet and all accessories — like new

This Crepas Decomaster dive watch was taken in as a partial trade for a Marathon watch.  The watch is essentially like new!  It was only worn a few times on another bracelet and then put back in case.

DECOMASTER 4000 was the fifth model from CREPAS WATCHES, the young watch brand which entered to the business 12 years back by launching the “Le Grand” model.  The DECOMASTER is an extreme diver with a water resistance to 4000 meters. The thickness of the crystal and case back has been increased to improve the water resistance. For this reason, the watch houses Caliber 2892-A2 instead of the traditional 2824-2, one millimeter thinner.

Crafted in solid stainless steel case, the DECOMASTER 4000 extreme diving watch boasts 120 position bezel with screws system to extracting, screwed crown and stainless steel case back, AR coated scratch-resistant sapphire crystal, and Automatic helium valve at 2’o clock.

The stainless steel case features brushed finished; straight, circular and radial effects.  In all a stunning watch with left side crown position.
