This vintage Omega Speedmaster Professional 105.012-66 CB offers a highly distinctive and collectible variation of the iconic chronograph, combining original design elements with naturally aged characteristics that set it apart. Produced in 1967, this example features the CB (La Centrale Boîtes) case—one of two case manufacturers for the reference—identified by its slightly flatter lug tops and subtle differences in profile.

The watch is defined by its striking tropical dial, which has developed a rich chocolate brown tone over time, complemented by deep patina on the hour markers and hands. Paired with a faded blue bezel—originally black but aged into a soft blue hue—the result is a uniquely warm and dynamic color palette rarely seen on standard Speedmaster examples. The addition of a brown strap further enhances this character, creating a cohesive and visually compelling presentation.

As one of the references worn during the Apollo era, the 105.012 holds an important place in Speedmaster history, representing the classic asymmetrical case design that became synonymous with the “Moonwatch.” Its balanced proportions, manual-wind chronograph movement, and enduring design continue to make it one of the most respected vintage sports watches in the market.

This example is offered in used vintage condition, with honest wear consistent with age. The case retains strong definition, the dial shows attractive and even tropicalization, and the bezel has naturally faded to a desirable blue tone. The watch is running as expected and presents as a highly character-rich collector piece.
