This professional-grade chronograph diver pairs formidable technical performance with the refined engineering you expect from Omega. The striking blue dial is matched to a blue unidirectional rotating bezel, with luminous hour markers and hands for legibility in any light. The dial layout includes a chronograph function with sub-dial displays and a date window, displayed under a scratch-resistant sapphire crystal.
Powering the watch is Omega's in-house Co-Axial Master Chronometer Caliber 9900 — a self-winding automatic movement with roughly 60 hours of power reserve, twin series-mounted barrels, and Omega's Co-Axial escapement for reduced friction and extended service intervals. The movement is METAS-certified as a Master Chronometer, meaning it's been independently tested for precision and resistance to magnetic fields up to 15,000 gauss — a level of certification that goes beyond standard COSC chronometer testing. A transparent sapphire caseback shows off the finely finished rotor and bridges.
Built to exacting dive-watch specifications, this Planet Ocean is water resistant to 600 meters (2000 ft), fitted with a screw-down crown and a stainless steel bracelet on a folding clasp for security. Despite its bold form factor, it is surprisingly comfortable for all-day wear.
