About the Omega Seamaster Planet Ocean

Omega launched the Seamaster Planet Ocean in 2005. The brand describes it as a dive watch that borrows style from its earlier models while using modern materials. Defining traits include 600 metres of water resistance, a helium escape valve, a unidirectional rotating diving bezel and the regular use of orange accents. Omega says its latest 42mm models mark a return to the original size, with a redesigned case and ceramic bezels. The current collection uses self-winding Co-Axial Master Chronometer movements, including calibre 8900, in 42mm, 43.5mm and 45.5mm cases, with GMT variants alongside the time-only models.
