Omega Speedmaster Professional Year: 1985 Rare ADB Case

A highly collectible vintage Omega Speedmaster Professional, reference ST 145.022, dating to approximately 1985. This distinctive example features the rare ADB case, the legendary manual-winding caliber 861, and an Omega service bracelet, representing an interesting variation of one of the most celebrated chronographs in watchmaking history.

The iconic black dial features three recessed chronograph registers, contrasting white hands, and the characteristic tachymeter bezel. Its timeless, highly legible design has remained closely associated with the Speedmaster Professional and its remarkable history in space exploration.

Inside beats the renowned Omega caliber 861, a manual-winding chronograph movement introduced in 1968. Known for its robust construction and reliability, this movement powered generations of Speedmaster Professional watches and played an important role in the model's continued development.

The stainless-steel case features the distinctive asymmetrical design with integrated crown and pusher protection. This example is particularly interesting for its ADB case, an uncommon variation appreciated by knowledgeable Speedmaster collectors. The watch is fitted with an Omega service bracelet rather than its original period bracelet.

The watch shows honest signs of previous use, consistent with its age. There is a visible dent on the bezel at approximately 9 o'clock, a scratch on the bezel insert between 1 and 2 o'clock, and a small section of tritium luminous material is missing from the hour hand. These imperfections are disclosed for complete transparency. Please refer to the photographs for a detailed assessment of the condition.
