GX-Diver's 41mm Gamma Green

This watch runs on the Swiss Sellita SW200-1 in Elaboré grade, a step above the standard version. It's regulated in three positions with tighter tolerances. Its 26 jewels and 28,800 vph beat give you a smooth, sweeping seconds hand and stable timekeeping, along with hacking seconds, a quickset date, and a minimum 41-hour power reserve when fully wound.

Behind the exhibition caseback, the custom LIV rotor winds the movement with every move of your wrist.

Every movement is individually tested before casing and ships with its own accuracy certificate. This one recorded -5 seconds per day, well within the Elaboré standard of ±7.

The 41mm Gamma Green starts with a solid, rugged case of surgical-grade 316L stainless steel, then takes on its dark gray tone through our Gray Color Fusion process, with the color fused into the steel so it will never come off under normal wear and tear. The 120-click unidirectional bezel carries a scratch-resistant polished green ceramic insert inlaid with BGW9 Swiss Super-LumiNova, so it stays sharp by day and glows at night. An anti-reflective sapphire crystal sits on top, the skeleton case back is fastened with actual screws for a secure seal, and the case is water-resistant to 300 meters.

• 120-click green ceramic bezel
• Screwed skeleton case back

The 41mm Gamma Green wears a gamma green multi-layer wave sandwich dial, with a sun-brushed center that gives the bold green real depth. Each hand-applied index is filled with BGW9 Swiss Super-LumiNova. The sword-shaped hour and minute hands are polished steel with lumed centers, and the orange second hand adds one more hit of color.

300m Water Resistance, Screw-Down Crown

This watch is water-resistant to 300 meters (30 bar), so it's built for swimming, snorkeling, and recreational scuba diving, as well as everything on land.

The screw-down crown threads tightly into the case and presses against a gasket to seal out water, dust, and pressure. Screw it in snugly after setting the time, and the case stays sealed.

• Water resistance: 300m / 30 bar / 1,000 ft
• Suitable for: swimming, snorkeling, recreational diving
• Crown: screw-down, with gasket seal

Sapphire Crystal, Front and Back

Both crystals are synthetic sapphire, rated 9 out of 10 on the Mohs scale, second only to diamond. Keys, zippers, and desk edges won't scratch either side.

The anti-reflective coating goes on the inside only, front and back. Outer coatings smudge and wear, so the surfaces you touch stay pure sapphire. You get a glare-free view of the dial and the movement.

• Material: synthetic sapphire, front and back
• Hardness: 9 out of 10 on the Mohs scale
• Coating: anti-reflective, inside only
• Outer surfaces: uncoated, for full scratch resistance
