Cosmonaut Nikolai Budarin's flown Omega Speedmaster Professional X-33 analog-digital watch used on the International Space Station during Expedition 6, carried to the station aboard the Space Shuttle Endeavour on STS-113, and returned on Soyuz TMA-1. The watch features a 41mm titanium case on a black leather Omega bracelet, engraved on the caseback with "Not For Sale, 13/A," and part numbers: "528-20991-1, 1035." In very good to fine cosmetic condition, with light scratches to the face and bezel, and heavy wear to the upper half of the watchband where it attaches to the body; function untested. Accompanied by a handwritten letter of provenance signed by Budarin, written on flown stationery, in part: "I certify that the Omega Speedmaster Professional with the serial No. 57179799 (528-20991-1) was used by me during the flight of ISS-6 on the International Space Station during intra station activity. Launched November 25, 2002 on the Space Shuttle Endeavour mission STS-113. Landing May 4, 2003 with the Soyuz capsule 'Soyuz TMA-1.'" Also includes three images of Budarin with the watch while writing and signing the letter. This particular watch was in space at the time of the STS-107 Space Shuttle Columbia disaster, which resulted in the indefinite suspension of Shuttle flights—the reason that it returned to Earth aboard Soyuz TMA-1.
Though more famous for the Speedmaster 'Moon Watch' used during the Apollo era, Omega's space heritage continued during the late 1990s with the Speedmaster X-33—a watch with modern amenities including a hybrid analog-digital display. In addition to the traditional hours, minutes, and seconds indicated by analog means, the digital portion offered extensive functions including universal GMT time, a perpetual calendar, and a chronograph.
