Price On Request

Featuring a matte black, high-contrast dial with crisp white markers and strong lume, it delivers timeless aesthetics that won’t feel dated years from now. Ideal for collectors who want a versatile diver that wears under a cuff and anchors a serious rotation.

Presents itself in mint condition with little to no signs of wear. Defines the dial with faceted rhodium markers and glowing Super-LumiNova for depth and low-light clarity without clutter. Built for secure grip, the unidirectional bezel pairs deep knurling with a black ceramic insert and engraved timing numerals. Showcases mechanical movement through the exhibition caseback—a visual feast for movement enthusiasts.

Functions include hours, minutes, seconds, date, and dive timing. The screw-down crown on the right side of the case sets the time and quick-sets the date. Used for dive timing, a unidirectional bezel tracks elapsed minutes by aligning its marker with the minute hand. Positioned at 10 o’clock, the helium escape valve automatically releases pressure during saturation diving, with no user input. Employs anti-magnetic materials to maintain accuracy around strong magnetic fields.

Comes as a full set, double-boxed with watch pillow, warranty card, and operating instructions.

Embodies proven performance in practical proportions made for real wrists. Balanced between dive-tool capability and refined finishing, its appeal lies in restraint, longevity, and quiet confidence.
