Key Features
- 30 ATM Water Resistance: Certified for depths up to 300 metres (1,000 feet), this watch is engineered for serious water activities including swimming, snorkeling, and recreational diving. The rating ensures protection against water ingress under pressure, giving peace of mind during aquatic adventures.
- Uni-Directional Rotating Bezel: Designed for accurate underwater timing, the bezel rotates only in one direction to prevent accidental movement that could lead to miscalculations during dives. This feature is essential for safety and precision when monitoring elapsed time beneath the surface.
- Super-LumiNova® Luminous Markers: The hands and hour markers are treated with Super-LumiNova®, providing excellent visibility in low-light or dark underwater environments. This ensures critical time readings remain clear when lighting is poor, enhancing both functionality and safety.
