Omega introduced its first Speedmaster chronograph in 1957. From 1962, NASA acquired several chronographs from famous manufacturers such as Rolex, Hamilton, Longines and Omega. It is only two years later that an official call for tenders is launched. Becoming the symbol of the space conquest, the choice of the Speedmaster was therefore the fruit of a long reflection and heavy specifications from NASA. Here the Omega presented is in yellow gold, a reduced size, with a self-winding movement : perfect representation of the expection of the 1990’s society.
