Omega Speedmaster Professional X-33 analog-digital watch for use on the Space Shuttle, featuring a 41mm titanium case on a black leather Omega bracelet, engraved on the caseback with NASA part numbers: "P/N 528-20991-1, S/N 1126." Includes a bag with affixed deaccession label, identifying this "Crew Pref, Watch Chronograph" as a Class III item. In very good to fine cosmetic condition, with light scratches to the face and bezel, and heavy wear to the watchband where it attaches to the case. Though the function is untested, the label on the bag is annotated in ballpoint, "Works."
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.
