GX-Diver's 44mm Black Full Lume

Featuring the new La Joux-Perret G100 24-jewel Swiss automatic, which boasts a formidable 68-hour power reserve. Set it down Friday, pick it up Monday, still keeping time.

Through the skeleton caseback you'll see its snailed finish and Côtes de Genève striping across the bridges. Every watch ships with its own accuracy certificate, verifying it runs within ±5 seconds per day in all positions, effectively zero drift, perfectly timed.

Dial: Full Lume Multi-layer wave pattern sandwich dial, with hand-applied indexes, filled with BGW9 Swiss Luminova.

Hands: Black Satin Sword-shaped hour & minute hands with BGW9 luminescence center. The second hand is orange and tipped with BGW9 Swiss Luminova

Rated to 300 meters / 1,000 feet, this case was engineered around, not simply stamped with. It begins as surgical-grade 316L stainless steel, the marine alloy chosen for its resistance to saltwater. The crown screws down against the case, and the skeleton caseback is bolted down with its own screws, drawn evenly onto its seal under mechanical tension rather than snapped into place. Pressure at depth bears on every seam at once, so how a case is closed matters as much as what it's made of.

This crystal is crafted from high-grade sapphire and features a scratch-resistant coating on the outside as well as an anti-reflective coating on the inside. Flawless legibility, built to last.
