• Automatic Mechanical Movement (Seiko NH36): Powered by the robust and widely respected Japanese-made Seiko NH36 caliber. This movement is automatic (self-winding via wrist motion), has 24 jewels, a 40-hour power reserve, and features both hacking (the second hand stops when setting the time) and hand-winding (can be manually wound via the crown).
• Sapphire Crystal with Anti-Reflective Coating: A high-quality sapphire crystal provides superior scratch resistance compared to mineral glass, and an anti-reflective coating improves readability, especially underwater.
• White Dial with Luminous Hands and Markers: Features a crisp white dial with strong, long-lasting luminous paint on the hands (often an orange minute hand for enhanced dive visibility) and hour markers, ensuring excellent readability in low-light conditions, crucial for diving.
• Helium Release Valve (HRV): A crucial feature for saturation divers, allowing helium molecules (which can enter the watch during extended deep dives) to escape safely during decompression, preventing the crystal from popping out.
