This rare Omega Speedmaster Professional X-33 Second Generation represents a pinnacle of modern aerospace horology, blending flight-qualified utility with a highly coveted chapter in Omega’s spacefaring legacy. Powered by the thermo-compensated multi-functional Calibre 1666 quartz movement, this reference was engineered strictly to meet the rigorous demands of military aviators and astronauts. It features highly specialized complications—including Mission Elapsed Time (MET), Phase Elapsed Time (PET), and a dual-caseback system designed to amplify its 80-decibel alarm through noisy spacecraft cabins. Omega ceased public civilian sales of the Gen 2 variant around 2010 to restrict procurement exclusively to military and government channels. The model was most recently seen on the wrists of the Artemis II crew as they orbited the Moon.

Presented in exceptional condition, this specific lot captures the rugged, utilitarian aesthetic of the definitive "Mars Watch." Its lightweight titanium case and highly legible hybrid analog-digital display, backlit by an integrated electroluminescent system, remain as functionally striking today as they were during active orbital missions. For the scholar of military timepieces or the dedicated space program enthusiast, this piece offers a distinct transitional bridge between mechanical heritage and modern digital precision. Do not miss the chance to acquire a piece of true aerospace history that is increasingly difficult to source on the open market.
