Omega Seamaster Planet Ocean 600M Co Axial 45.5 mm – Ref. 232.30.46.21.01.001 – Full Set on Rubber Strap

Experience a modern Omega dive icon with this Seamaster Planet Ocean 600M Co‑Axial Chronometer, reference 232.30.46.21.01.001, offered here as a complete full set on a black rubber strap. Designed for professional divers yet refined enough for everyday wear, this 45.5 mm Planet Ocean balances rugged capability with unmistakable Omega styling.

The stainless‑steel case measures approximately 45.5 mm and is fitted with a domed sapphire crystal and unidirectional rotating dive bezel, giving this watch serious tool‑watch credentials. Its deep black dial features luminous hour markers and bold arrow hands, Arabic numerals at 6, 9, and 12, and a date window at 3 o’clock for practical daily functionality. With water resistance to 600 m / 2000 ft, a screw‑down crown, and a helium escape valve, the Planet Ocean 600M is built to perform far beyond recreational depths.

Housed inside is Omega’s in‑house Co‑Axial caliber 8500 automatic movement, visible through the sapphire exhibition caseback. This chronometer‑certified movement provides an approximate 60‑hour power reserve and features Omega’s Co‑Axial escapement for improved long‑term precision and durability. Paired with a black rubber strap and stainless‑steel buckle, the watch wears securely and comfortably, making it an excellent choice for both water activities and daily rotation.

This example is sold as a full set, including the original Omega presentation box and pictogram/warranty cards as pictured, adding collectible value and peace of mind. The timegrapher reading shown in the photos indicates healthy rate and amplitude at the time of testing, though accuracy may vary in real‑world wear.
