Key Features

• Automatic Self-Winding Movement
  Powered by SEIKO’s reliable 4R36 caliber, this watch operates through kinetic energy generated by the wearer’s arm movements. The self-winding mechanism ensures continuous operation without batteries, while also supporting manual winding for added convenience. This movement includes a hacking function for precise time setting and a 41-hour power reserve, ensuring accuracy and reliability whether worn daily or stored between uses.
• 200-Meter Water Resistance
  Engineered for serious water enthusiasts, this dive watch meets ISO standards for water resistance up to 200 meters (660 feet). It is suitable for swimming, snorkeling, and recreational scuba diving, offering peace of mind in high-pressure underwater environments. The screw-down crown and reinforced case back enhance sealing integrity, protecting internal components from moisture and pressure.
• Unidirectional Rotating Bezel
  The functional rotating bezel allows divers to track elapsed time underwater, a critical safety feature during dives. Crafted for precision and durability, the bezel features clearly marked graduations and a secure grip for easy adjustment, even with gloves. Its unidirectional design prevents accidental overcounting, ensuring accurate dive time monitoring.
• LumiBrite Luminous Markers
  For enhanced visibility in low-light or underwater conditions, the watch is equipped with SEIKO’s proprietary LumiBrite technology on the hour markers and hands. This photoluminescent material charges quickly under any light source and glows brightly in the dark, offering superior legibility compared to traditional luminous paints. It ensures time can be read clearly at night or during deep dives.
• Durable Hardlex Crystal
  The watch face is protected by a Hardlex crystal, a proprietary mineral glass known for its scratch resistance and clarity. While not as hard as sapphire, Hardlex offers excellent durability for everyday wear and resists minor abrasions, maintaining a pristine appearance over time. It strikes a balance between resilience and optical quality, ideal for active lifestyles.
