Der NEUE GX-Diver 44 mm Ocean Blue

This watch runs on the La Joux-Perret G100, a newer-generation Swiss automatic built in La Chaux-de-Fonds. Its standout feature is a 68-hour power reserve. Take it off Friday night, and it's still running Monday morning.

The G100 has 24 jewels and beats at 28,800 vph for a smooth, sweeping seconds hand. It includes hacking seconds and a date. It's finished to a soigné standard with Côtes de Genève striping, visible through the exhibition caseback.

Accuracy is rated at ±5 seconds per day, tighter than most movements in its class.

The 44mm Ocean Blue 2.0 is built on a solid, rugged case of surgical-grade 316L stainless steel with a brushed finish, left unplated so raw steel frames the dial. The 120-click unidirectional bezel carries a scratch-resistant polished blue 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.

The 44mm Ocean Blue 2.0 wears a bright turquoise multi-layer wave sandwich dial, the color of shallow tropical water, with a wave-patterned top layer that shifts as the light changes. Each hand-applied index is filled with BGW9 Swiss Super-LumiNova. The sword-shaped hour and minute hands are heat-treated blue with lumed centers, and the orange second hand pops against the turquoise.

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
