Omega Seamaster Planet Ocean 600M Co-Axial Chronometer

This is a premium Swiss-made luxury diver's watch, specifically the Omega Seamaster Planet Ocean model with a distinctive orange aluminum bezel. The watch features a substantial brushed and polished stainless steel case, typically measuring approximately 42mm or 45.5mm in diameter. It is equipped with a matching integrated stainless steel bracelet with curved end links and a fold-over clasp. The matte black dial features applied luminous baton hour markers, with stylized Arabic numerals at the 12, 6, and 9 positions in a matching orange hue. A date window is located at the 3 o'clock position. The arrow-tipped broadsword hands are coated in Super-LumiNova for low-light visibility. Notable technical features include a helium escape valve at the 10 o'clock position and a screw-down crown at 3 o'clock, supporting a water resistance rating of 600 meters (2000 feet). The dial text confirms it contains a Co-Axial chronometer movement. The condition appears to be excellent, showing minimal signs of wear on the bezel and crystal, though light micro-scratching may be present on the polished case sides and bracelet links consistent with gentle use. This design reflects the modern era of Omega craftsmanship, dating roughly to the mid-2000s or early 2010s.

I have conducted a visual examination of the Omega Seamaster Planet Ocean 600M, specifically the first-generation Ref. 2208.50.00 or 2209.50.00. The watch presents a high level of finish consistent with Omega’s caliber 2500 series production. The signature orange bezel shows no significant fading or impact marks, while the dial's matte finish and applied indices appear crisp. The helium escape valve is correctly positioned at 10 o'clock, and the bracelet integration looks seamless. This specific 'Big Size' orange aesthetic is a cult favorite among collectors, marking the era when Omega redefined itself against the Rolex Submariner. The current market for neo-vintage Omega remains strong, with values for these early Co-Axial models appreciating steadily due to their robust tool-watch builds and iconic colorways. Comparables on secondary markets such as Chrono24 and eBay currently settle in the mid-$4,000 range for pieces in excellent condition. However, a digital image cannot confirm the internal mechanical health of the Co-Axial escapement or the presence of the red wax seal on the case back indicating it hasn't been tampered with. To fully authenticate this piece, I would require an in-person inspection of the movement serial numbers, verification of 'Pictograms' and 'Chronometer' warranty cards, and a pressure test for water resistance. While the visual details—such as the date wheel font and the lume application—align with genuine production, definitive authentication requires checking the movement's beat rate and balance wheel architecture.
