Horological context

The Speedmaster was launched by Omega in 1957 within its Professional line, designed for motorsport: the first wristwatch to carry its tachymeter scale on the bezel rather than the dial. A three-register chronograph driven by the calibre 321 (from 1957 to 1968), then by the calibre 861 from 1968 onwards. The asymmetric case with shoulders protecting the crown and pushers appeared in 1963 with reference 105.012 — the very one that would reach the Moon. On 1 March 1965 the Speedmaster officially became the chronograph qualified by NASA for all manned missions, after a battery of extreme tests. On 21 July 1969 it was the first watch worn on the Moon during Apollo 11, earning its Moonwatch nickname and its standing as a legendary model. The following year, during the Apollo 13 emergency, the crew used it to manually time the engine burn decisive for their return; NASA then awarded Omega its Silver Snoopy Award. Collectors distinguish the pre-Moon models, made before July 1969, from the Moonwatch proper.

Character

Black dial with silvered concentric registers and starlit midnight blue moonphase disc, the early patina shifting toward blue-black. The calibre 1866 extends the historical lineage of Speedmaster chronographs — 321, 861, 1861. The modern Moonwatch with complications.

Watch serviced. Very good state. Delivered with its Omega box and the Contre-Temps 24-month warranty certificate.
