While many commemorative endeavors were made for various space missions and accomplishments, the present watch is actually part of an aerospace project, as it physically stayed in space for 365 days at the MIR space station, earning the coveted title of a "flown" wristwatch.

MIR, meaning peace or world in Russian, was a space station that operated in low Earth orbit from 1986 to 2001, serving as a microgravity research laboratory. One of the research projects that was conducted on the MIR was in July 1993, which allowed for 35 Speedmaster Professionals to be taken to the space station for 365 days with the purpose of observing and forming the effects of microgravity on watch movements. There are in total 28 stainless steel examples, and 7 pieces in yellow gold. After the 35 Speedmaster Professionals were tested on MIR, flown in space, returned to Earth, Omega scrutinized them and later offered them for sale with an engraved case back noting this epoch-defining milestone.

The watch is preserved in overall excellent condition, with virtually no visible scuffs or signs of wear. The exact same watch is, numbered 12/28, is featured in Grégoire Rossier and Anthony Marquié, Moonwatch Only: 60 Years of Omega Speedmaster. Completed with its original accessories, the present lot is an unmissable chance for watch lovers and space enthusiasts to own mementos which chronicle one of the most important space missions in the history of humanity.
