A Legacy of Precision and Adventure

Omega’s Seamaster line, launched in 1948, has long been synonymous with reliability in extreme conditions. The Planet Ocean collection introduced in 2005 builds on this foundation, designed to meet the demands of professional divers while incorporating modern advancements.

Technical Specifications

  • Case and Build:

    • Material: The 45.5mm case is crafted from brushed stainless steel, offering corrosion resistance and durability for underwater and everyday environments.
    • Bezel: A unidirectional rotating bezel, made from brushed black ceramic with a Liquidmetal™ diving scale, allows divers to track elapsed dive time accurately.
    • Crystal: A scratch-resistant sapphire crystal protects the dial, ensuring clarity even in harsh conditions.
    • Water Resistance: Rated to 60 bar (600 meters / 2000 feet), the watch is built for professional diving, featuring a helium-escape valve for saturation diving and a screw-down crown for enhanced security.


  • Dial and Readability:

    • The sand-blasted “gunmetal” grey dial, treated with a galvanic finish, ensures clear legibility.
    • Beige Super-LumiNova on the hands and hour markers glows brightly in low-light settings, such as underwater, for optimal readability.
    • Sub-dials include a small seconds counter, 60-minute, and 12-hour chronograph counters, with a date window at 6 o’clock for added functionality. 
    • Strap: A grey rubber strap with a stainless steel folding clasp provides durability and comfort for active use, including diving.

Cutting-Edge Movement: Co-Axial Master Chronometer Calibre 9900

At the heart of the Seamaster Planet Ocean Chronograph 600M is Omega’s Co-Axial Master Chronometer Calibre 9900, a self-winding movement renowned for its precision and reliability. Certified by METAS (The Swiss Federal Institute of Metrology), it undergoes eight rigorous tests to ensure:

    • Accuracy: Exceptional timekeeping under various conditions.
    • Magnetic Resistance: Protection against magnetic fields up to 15,000 gauss, critical for modern environments with electronic devices.
    • Power Reserve: A 60-hour power reserve ensures reliable performance over extended periods. The Calibre 9900 drives the chronograph functions, including elapsed time tracking via the sub-dials, making it versatile for both diving and land-based activities.
Functionality for Divers and Enthusiasts

The 215.32.46.51.01.004 is engineered for professional diving but versatile enough for broader use:

    • Dive-Ready Features: The 600-meter water resistance and helium-escape valve make it suitable for deep-sea exploration, including saturation diving.
    • Chronograph Precision: The chronograph allows precise timing of events, whether measuring dive durations or tracking performance in other activities.
    • Durability: The combination of stainless steel, ceramic, and sapphire crystal ensures the watch withstands extreme conditions, from ocean depths to daily wear.

Why It Stands Out

The Omega Seamaster Planet Ocean Chronograph 600M is a testament to Omega’s ability to blend heritage with innovation. Its METAS-certified movement guarantees unmatched accuracy and resilience, while its dive-specific features—such as the helium-escape valve and unidirectional bezel—cater to professional divers. The watch’s robust construction and versatile chronograph functionality also appeal to collectors and enthusiasts who value precision and reliability in a luxury timepiece.

Final Thoughts

The Omega Seamaster Planet Ocean Chronograph 600M Grey 45.5mm (215.32.46.51.01.004) is more than a watch—it’s a tool for adventure and a symbol of Omega’s enduring commitment to excellence. Whether you’re navigating the ocean’s depths or appreciating its technical prowess, this chronograph delivers performance and precision in equal measure. For those seeking a dive watch that combines cutting-edge technology with a storied legacy, this model is a compelling choice.
