The 1964 Omega Speedmaster Professional A.C.P. Ref. 105.012-63 is one of the rarest and most historically significant early Speedmasters, representing the model’s original connection to motorsport before its identity became inseparable from NASA and space exploration. In 1964, just 50 examples of the 105.012-63 were delivered to the Automóvil Club Peruano (A.C.P.), Peru’s prominent motorsport organization, with research documenting the group’s delivery on July 2, 1964. These watches are distinguished by the additional “A.C.P.” signature printed beneath “Speedmaster Professional” on the black dial, along with the unusual early “SWISS MADE” designation without the later flanking T markings. The 105.012 itself is an important reference in Speedmaster history, introducing the asymmetrical case with protective crown and pusher guards and being among the earliest references to carry “Professional” on the dial.
Inside is Omega’s legendary manually wound Calibre 321, a 17-jewel column-wheel chronograph movement that would later become famous for its role in NASA’s Apollo missions. Period A.C.P. examples occupy an exceptionally narrow 20.520.xxx movement-number range, further helping distinguish these watches from standard 105.012-63 production. Phillips has documented an A.C.P. example accompanied by an Omega Extract from the Archives confirming its sale to the Automóvil Club Peruano on July 2, 1964, while specialist research indicates that only a small number of the original 50 watches have surfaced publicly. With its factory A.C.P.-signed dial, tiny production quantity, Calibre 321 movement, early Professional-era case architecture, and direct connection to Peruvian motorsport, the 105.012-63 A.C.P. captures the Speedmaster at a fascinating crossroads, created first and foremost as a racing chronograph, immediately before it became the definitive watch of human spaceflight.
