Condition: Used Very Good – with Box and Papers

The Omega Seamaster Planet Ocean 600M (Ref. 232.30.42.21.01.003) is built as a true modern dive watch, combining Omega’s in-house movement with serious real-world capability. This 42mm version keeps the proportions wearable while still delivering the presence and durability the Planet Ocean line is known for.

The black dial with orange accents is one of the most recognizable configurations in the lineup, offering strong contrast and excellent legibility. The ceramic bezel adds durability and depth, and the overall design leans more toward a purpose-built tool watch than a dress-leaning sport piece.

Rated to 600 meters of water resistance, this watch is equipped for professional use, with a screw-down crown and helium escape valve. It’s overbuilt in the best way—designed to handle demanding conditions while still being practical enough for everyday wear.

Inside is Omega’s Caliber 8500 Co-Axial movement, known for its reliability and smooth operation, with a ~60-hour power reserve and a display caseback that shows off the twin-barrel layout.

This watch is like new. Crystal is clean. The dial, bezel, and strap show no visible wear. Please review all photos for the exact condition.
