This reference is the first gold Speedmaster, limited to 1,014 numbered units. It features an 18k yellow gold case and a matching \"President\" style bracelet with hollow links. Collectors prioritize this model for its solid gold \"OM\" (Or Massif) dial with applied onyx indices and its burgundy aluminum bezel insert. The watch houses the manual-wind Calibre 861 movement. Numbers 1 through 28 were gifted to NASA astronauts and government officials, while the remaining units were sold to the public. On the secondary market, prices typically range from $50,000 to over $100,000 depending on the presence of the original \"crater\" box and the condition of the bezel. In 2022, an example belonging to astronaut Wally Schirra sold at auction for approximately $1.9 million.", "score": 200}]}
