Seamaster Planet Ocean 600M Co-Axial 45.5 Chronograph Stainless Steel / Black / Rubber / Olympic Timeless

The Planet Ocean was introduced in 2005 as the Seamaster range's high-performance diver — larger, more robust, and rated to 600 metres, significantly beyond the Diver 300M's depth rating. The collection draws its design language from Omega's deep-sea heritage, including the brand's role in supplying watches for COMEX diving operations. Larger case sizes, broader bezels, and more aggressive proportions distinguish the Planet Ocean from its siblings, positioning it as Omega's most serious tool-watch offering within the Seamaster family. Co-Axial movements and Master Chronometer certification ensure the mechanical specification matches the physical capability.

The Omega Seamaster Planet Ocean 222.32.46.50.01.001 was introduced in 2008 in celebration of Omega's role as official timekeeper to the Olympic Games. Its dial has a vintage Omega logo and Arabic numerals. The Olympic rings function as a counterweight to the chronograph seconds hand.
