Seamaster Planet Ocean 600M Co-Axial 37.5 Chronograph Stainless Steel / Diamond / Black / Alligator

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 Seamaster Planet Ocean reference 222.18.38.50.01.001 has a stainless steel case of 37.5mm and a diamond-set bezel. It is powered by caliber 3313.
