Key Features

• Japanese Automatic NH05 Movement – Powered by a self-winding automatic movement, this watch maintains precise timekeeping without the need for battery replacements. With a 40-hour power reserve, it keeps accurate time both on land and underwater, ensuring reliability during extended wear.
• 200m Water Resistance – Rigorously pressure-tested to withstand depths up to 200 meters, this dive watch is suitable for recreational scuba diving, snorkeling, and other water-based activities. It offers dependable performance in demanding underwater environments.
• Sapphire Crystal with Anti-Reflective Coating – The watch face is protected by scratch-resistant sapphire crystal, enhanced with an anti-reflective coating that improves visibility in bright conditions—critical for monitoring dive times and maintaining orientation underwater.
• Unidirectional Rotating Bezel – The dive-ready bezel allows divers to track elapsed time safely. Its unidirectional rotation prevents accidental overestimation of remaining air supply, a key safety feature for underwater exploration.
• Fold-Over Clasp with Two-Button Deployment – The stainless steel bracelet features a secure diver-style clasp with a fold-over lock and dual-button release, ensuring the watch stays firmly in place during active use or sudden movements.
