Key Features

• Japan VH31 Sweep Second Movement: This high-precision quartz movement delivers a smooth, uninterrupted sweep of the second hand, ensuring consistent timekeeping with minimal maintenance. Its reliability makes it ideal for divers and outdoor enthusiasts who depend on accurate time measurement in critical situations.
• Grade 2 Titanium Case: Renowned for its strength-to-weight ratio, Grade 2 titanium provides exceptional durability while remaining significantly lighter than stainless steel. It resists saltwater corrosion and daily wear, making it perfect for marine environments and long-term use.
• Flat Sapphire Crystal with AR Coating: The scratch-resistant sapphire glass protects the dial from impacts and abrasions, while the high-clear anti-reflective (AR) coating reduces glare—enhancing readability in bright sunlight or underwater where visibility is crucial.
• 60-Click Bidirectional Ceramic Bezel: The unidirectional rotation with 60 tactile clicks ensures precise timing during dives. The ceramic insert is highly resistant to fading, scratches, and corrosion, and features a full BGW9 Super Lume application for clear visibility in low-light conditions.
• Super Luminous BGW-9 Blue Light: Applied generously to the dial, hands, and hour markers, this advanced lume emits a bright blue glow that remains visible for extended periods in complete darkness—essential for night dives or murky underwater environments.
• Screw-Down Crown and Case Back: These critical sealing points ensure maximum protection against water and dust ingress, maintaining the watch’s integrity at depth and during prolonged submersion.
• EXD (Exchangeable X Design): A unique lug system that enables quick, tool-free strap changes. Users can easily switch between NATO, rubber, leather, or metal straps to match different activities or styles—ideal for transitioning from dive gear to everyday attire.
• 20mm Titanium Buckle Strap: Includes a matching titanium buckle for a cohesive, premium appearance. The strap is designed for durability and comfort, with heavy-duty 316L stainless steel spring bar pins that resist rust, bending, and breakage under stress.
• 200-Meter Water Resistance: Certified for serious water use, this watch meets the demands of recreational and professional diving, as well as high-impact water sports like surfing and jet skiing.
