Men's 1000m Automatic Diver Watch Sapphire Steel

Built for Serious Diving, Engineered for Daily Wear

This men's 1000m automatic diver's watch is designed for demanding underwater environments while maintaining a refined, everyday look. Powered by a Japanese NH35 automatic mechanical movement, it offers dependable accuracy without the need for a battery, winding itself as you move. With a helium exhaust valve, screw‑down crown, and robust 316L stainless steel construction, it is configured for deep diving, water sports, and long-term use on land and at sea.

The case is crafted from brushed 316L stainless steel with a screw‑in bottom cover for enhanced sealing. At 46 mm in diameter and 13.8 mm in thickness (including crystal and caseback), it provides strong wrist presence while remaining wearable for daily activities. The stainless steel bracelet is designed for strength and stability, with a total watch length of 260 mm to fit a wide range of wrists. A ceramic unidirectional bezel with 120‑click rotation allows precise timing of dives, training intervals, or daily tasks.

The double synthetic sapphire crystal features an anti‑glare blue coating to improve legibility in bright sun or underwater. The dial uses an Asian black high‑visibility surface with Swiss C3 super‑luminous coating, delivering a strong green glow in low light. The bezel markers use Swiss BGW9 + C3 luminous powder in blue‑green for clear orientation in darkness. Hour, minute, and seconds hands are treated with matching Swiss C3 luminous material, ensuring the time remains readable in murky water, at night, or in low‑light indoor settings.

The movement inside is the Japan NH35 automatic mechanical caliber, operating at 21,600 vibrations per hour (3 Hz). It features three hands with calendar, hacking seconds for precise time setting, two‑way automatic winding, 24 jewels, and approximately 41 hours of power reserve. This configuration supports smooth operation, reduced wear, and consistent performance over time. A screw‑down crown measuring 7.5 mm in diameter enhances grip and contributes to the watch's 1000‑meter water‑resistant rating. An integrated exhaust valve supports deep diving conditions where gas buildup can occur.
