Key Features

• Co-Axial Master Chronograph Movement – Powered by Omega’s in-house Co-Axial Master Chronograph caliber, this watch delivers exceptional precision and reduced friction, enhancing long-term reliability and minimizing maintenance needs. The co-axial escapement, a hallmark of Omega’s innovation, reduces wear on components, contributing to smoother operation and extended service intervals.
• Chronometer Certified – Officially certified as a chronometer by the Swiss Official Chronometer Testing Institute (COSC), the movement meets rigorous accuracy standards, ensuring consistent performance across varying temperatures and positions. This certification underscores Omega’s commitment to precision in every detail.
• 300m Water Resistance – Engineered for serious diving, the watch is water-resistant up to 300 meters (30 bar), making it suitable for recreational scuba diving, snorkeling, and other water sports. The robust construction and secure screw-down crown help maintain integrity under pressure.
• Black Dial with Luminous Markers – The sleek black dial features high-contrast luminous hour markers and hands, treated with Super-LumiNova for long-lasting glow. This ensures excellent legibility in low-light conditions or during night dives, enhancing safety and usability.
• Automatic Winding System – The self-winding mechanism harnesses motion from the wearer’s wrist to power the watch, eliminating the need for manual winding or battery replacements. This makes it a practical choice for daily wear, as long as it remains in regular use.
• Durable Stainless Steel and Titanium Construction – Built with a combination of stainless steel and titanium, the case and bracelet offer strength, corrosion resistance, and a lightweight feel for all-day comfort. Titanium’s natural resistance to saltwater and sweat makes it ideal for marine environments.
• Unidirectional Rotating Bezel – The bezel allows divers to track elapsed time underwater safely, with a clear, easy-to-read scale and secure grip for adjustments. Designed to turn only counterclockwise, it prevents accidental overestimation of remaining air supply, a critical safety feature for divers.
