The Watch: The Seamaster Planet Ocean 600M is Omega’s boldest dive watch, and this version in full titanium elevates the design with a lightweight, ultra-durable case and bracelet. Reference 215.90.44.21.99.001 features a sandblasted titanium dial with applied indices, a matching ceramic bezel with Liquidmetal diving scale, and a helium escape valve at 10 o’clock—all the hallmarks of Omega’s most serious tool watches.
At 43.5mm, this model has strong wrist presence without excessive weight, thanks to its Grade 5 titanium construction. The Co-Axial Master Chronometer caliber 8900 inside is METAS-certified, anti-magnetic to 15,000 gauss, and visible through the sapphire caseback.
This example comes as a full set, including box and papers. It has been lightly worn, with small marks on the clasp, but remains in excellent condition overall.
Condition: Excellent pre-owned condition with minor wear on the clasp. Running well, with full functionality.
Includes: Original box, manual, warranty cards, and titanium bracelet.
