The applied gold-tone baton indices are elevated with black inserts, adding striking contrast and legibility.

The original gold-tone baton hands mirror the indices with matching black inserts and retain their luminous material, aging gracefully alongside the subtle luminous pips positioned at the outer edge of each hour marker. The typography, from the applied Omega logo to the graceful Seamaster Cosmic script, remains factory crisp with no print loss.

Case and Crystal
The 35 millimeter gold-plated tonneau case exhibits strong, well-defined geometry characteristic of the Cosmic line. The transition between the vertically brushed upper surfaces and the polished case flanks remains sharp and distinct, indicating careful preservation. Honest signs of vintage wear, including superficial scratches and minor handling marks on the polished sides, are present but do not detract from the watch's impressive wrist presence. The original Omega-signed crown is securely fitted. The solid unishell caseback features a deeply engraved Seamaster Hippocampus emblem, alongside clear Waterproof and Tool 107 engravings, showcasing excellent definition. A domed acrylic crystal protects the dial, remaining clear and highly legible with only faint, age-appropriate surface wear visible under close inspection.

History
Introduced in the late 1960s, the Seamaster Cosmic series represented Omega's embrace of modernist design language, moving away from traditional round cases toward dynamic, cushion, and tonneau shapes. The use of the unishell case, requiring the movement to be accessed through the crystal using a special tool, was an engineering solution designed to eliminate the vulnerable caseback gasket, thereby improving water resistance. This era of Omega production is widely celebrated for yielding some of the most reliable and aesthetically distinct watches of the twentieth century.
