Pre-owned Omega Seamaster Planet Ocean ref 215.30.44.22.01.001 (2023). Originally introduced in 2005, the Planet Ocean carries Omega’s long maritime legacy into modern waters. It has serious dive functionality with sleek, everyday style. This 43.5mm model is a bold choice with its black ceramic dial, classic Arabic numerals, and a GMT hand for tracking a second time zone. Perfect for travelers and ocean explorers alike. The polished black-and-white bi-ceramic bezel isn’t just striking to look at. It also separates day and night hours at a glance. Flip it over and you’ll find the Master Chronometer calibre 8906 ticking away beneath a sapphire caseback. As with every Planet Ocean, this watch is water-resistant to 600 meters with a helium escape valve. Shop OMEGA Seamaster Collection
