It's packed with all the features you'd expect from a top-of-the-line dive watch, including a unidirectional bezel and water resistance up to 1000 meters. It's the ultimate companion for all your underwater adventures.

Our offering is in superb condition and comes in a full set, complete with an OEM orange strap and the original bracelet, as well as an additional bezel for good measure (a black rubber strap with folding buckle is also present, but worn quite a lot). Ticking per specs.
