Omega Seamaster Planet Ocean 600M Black 43.5mm

About This Watch

The Omega Seamaster Planet Ocean 600M is the brand's most capable dive watch, rated to 600 meters — twice the depth of the Seamaster 300M. The 43.5mm case houses the caliber 8900, one of Omega's premier movements with Master Chronometer certification, Co-Axial escapement, and a 60-hour power reserve. The black ceramic bezel with Liquidmetal diving scale is a technological marvel, where a liquidmetal alloy is bonded directly into the ceramic grooves for exceptional legibility and scratch resistance. The case is thicker and more robust than the 300M, with a prominent crown guard and substantial helium escape valve at 10 o'clock. While the 300M is often chosen as a lifestyle watch, the Planet Ocean is for those who prioritize diving capability and want a watch that can handle serious underwater activity. The movement features two barrels for the extended power reserve and a silicon balance spring for long-term stability. This is the Seamaster you choose when 300 meters simply is not enough.
