Unworn, Omega Seamaster Planet Ocean 600M, Ref# 217.32.42.21.01.002, box and papers.

The OMEGA Seamaster Planet Ocean 600M Ref. 217.32.42.21.01.002 is a professional diving timepiece that showcases OMEGA's latest innovations in underwater watchmaking. Designed for extreme performance while maintaining refined everyday wearability, this 42 mm model features a robust stainless steel case paired with a comfortable integrated blue structured rubber strap. The unidirectional blue ceramic bezel, enhanced by a white enamel diving scale and a Grade 5 titanium bezel ring, frames a matte black dial with rhodium-plated hands, applied indexes, and four Arabic numerals, all filled with white Super-LumiNova® for outstanding visibility in the darkest conditions. A flat scratch-resistant sapphire crystal with anti-reflective treatment on both sides ensures exceptional clarity, while the screw-in crown and helium escape valve underline the watch's professional diving capabilities. At its heart beats the OMEGA Co-Axial Master Chronometer Calibre 8912, a METAS-certified self-winding movement offering exceptional precision, resistance to magnetic fields up to 15,000 gauss, and an independently adjustable hour hand for effortless time-zone changes. Twin barrels mounted in series provide a reliable 60-hour power reserve, while the Grade 5 titanium caseback, engraved with the iconic Seamaster Seahorse medallion, pays tribute to the collection's rich maritime heritage. Water-resistant to an impressive 600 meters, this Planet Ocean combines cutting-edge technology, outstanding durability, and timeless Swiss craftsmanship.
