Omega Speedmaster Professional X-33 analog-digital watch for use on the Space Shuttle, featuring a 41mm titanium case on a standard black Omega bracelet, engraved on the caseback with NASA part numbers: "P/N 528-20991-1, S/N 1073." In fine cosmetic condition. Function untested.
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.
Provenance: The Spaceflight America Museum and Science Center in Prince Frederick, MD.
