Pre-owned Omega Seamaster Planet Ocean ref 215.30.44.21.03.001 (2019) sits on the more serious end of Omega’s dive watch lineup. The Planet Ocean collection was introduced in 2005 as a modern, more robust counterpart to the standard Seamaster Diver 300M, with higher depth ratings and a slightly more technical feel overall. This one comes in a 43.5mm stainless steel case, paired with a blue ceramic dial and matching ceramic bezel. The ceramic gives it a clean, glossy look while also being highly resistant to scratches. Arabic numerals make sure the dial is easy to read. It’s made to handle real conditions, with water resistance rated all the way to 600 meters. Inside is the Master Chronometer caliber 8900, visible through the caseback, offering strong accuracy, anti-magnetic resistance, and a 60-hour power reserve. Shop OMEGA Seamaster Collection
