The Omega 600M Seamaster Planet Ocean 45 mm men’s watch with a classic black dial paired with the bold orange bezel from Omega’s late-2000s era. The 45.5mm case gives it real wrist presence without feeling overdone, and the oversized orange numerals are unmistakably Planet Ocean.

The watch is powered by Omega’s Caliber 2500 Co-Axial movement, an important chapter in Omega’s modern history and the foundation of their current Co-Axial designs. With a 600-meter depth rating, screw-down crown, and helium escape valve, this is a true professional dive watch that still wears well day to day.

A well-kept, early-generation Planet Ocean and a reference that remains highly recognizable and sought after — especially in this original orange-bezel configuration.
