OMEGA’s Planet Ocean line was created in honor of the brand’s deep-rooted maritime legacy. This preowned 2025 Seamaster Planet Ocean 600M Master Chronometer continues that tradition, combining professional dive capability with refined, modern design. This timepiece features a scratch-resistant sapphire crystal protecting a striking blue ceramic dial, complete with Arabic numerals and a date window at the 3 o’clock position. A matching blue ceramic unidirectional bezel, enhanced with OMEGA’s Liquidmetal™ diving scale, frames the dial and is mounted on a robust 43.5 mm stainless steel case. Additional details include an alveol screw-in caseback and a stainless steel bracelet fitted with OMEGA’s patented extendable foldover clasp for comfort and security.

Built for extreme conditions, this timepiece offers an impressive water resistance of 600 metres (2000 feet / 60 bar) and is equipped with a helium-escape valve for professional diving use. This watch is powered by the OMEGA Master Chronometer calibre 8900, visible through the transparent caseback. Certified by METAS (The Swiss Federal Institute of Metrology), the movement has successfully passed eight rigorous tests, ensuring exceptional precision, performance, and magnetic resistance. The condition of this timepiece is good, with the exception of minor scratches throughout the case and bracelet, consistent with general wear. This watch is accompanied by its original outer box, inner display box, card holder, Pictograms card, Master Chronometer card, International Warranty card dated 2025, and operating instructions.
