The Omega Seamaster Planet Ocean Ref. 2201.51 is a classic example of the first-generation Planet Ocean collection, combining professional diving capability with Omega's distinctive early Co-Axial design.

The 42mm stainless steel case features a black dial with contrasting orange Arabic numerals at 6, 9, and 12 o'clock, luminous hands and hour markers, and a black unidirectional rotating dive bezel. The stainless steel bracelet complements the watch's robust design, while the helium escape valve and 600-meter water resistance reflect its professional diving heritage.

Powered by Omega's Co-Axial Calibre 2500 automatic chronometer movement, the watch provides approximately 48 hours of power reserve and combines traditional Swiss mechanical watchmaking with Omega's Co-Axial escapement technology.

This example is dated February 19, 2012, and comes as a full set. The watch itself remains in excellent pre-owned condition and is running strong.

Please note that the interior of the original presentation box exhibits peeling and deterioration, as shown in the accompanying photographs. This is limited to the box and does not affect the watch.
