Key Features

• Blue Dial with High Visibility – The rich blue dial enhances legibility through strong contrast against luminous hour markers and hands. This design is especially effective in low-light or underwater settings, where clarity is essential. The uncluttered layout maintains a clean, modern appearance while prioritizing functionality.
• Two-Tone Stainless Steel and 18kt Sedna Gold Case and Band – The 42 mm case and matching bracelet are crafted from a combination of brushed and polished silver-tone stainless steel, accented with 18kt Sedna gold. This material blend delivers a distinctive visual balance, offering sporty durability with a touch of luxury. The bracelet’s integrated design ensures a smooth, comfortable fit on the wrist.
• Automatic Movement with Chronometer Certification – Powered by a self-winding mechanical movement, this watch harnesses the motion of the wearer’s wrist to stay wound. Certified by the Swiss Official Chronometer Testing Institute (COSC), it meets rigorous precision standards, maintaining accuracy within -4 to +6 seconds per day. This certification reflects Omega’s commitment to superior timekeeping performance.
• 300 Meters / 1000 Feet Water Resistance – Engineered for serious aquatic use, this watch is suitable for recreational scuba diving, snorkeling, swimming, and other water-based activities. Its robust construction and sealed case back ensure reliable performance even at significant depths, making it a trusted companion for underwater adventures.
• Uni-Directional Rotating Bezel – The bezel turns only in one direction, a critical safety feature that prevents accidental over-rotation during dives. This allows divers to safely track elapsed time underwater. The bezel offers precise, tactile feedback with each click, ensuring accurate adjustments even when wearing gloves.
• Fold Over Clasp with Push Button Release – The clasp secures the bracelet firmly around the wrist, minimizing the risk of accidental opening during physical activity. The dual push-button release mechanism makes it easy to put on and take off, while also allowing for quick adjustments for comfort and fit.
