In 1997 Omega created the Speedmaster Missions set to commemorate the 40th anniversary of the Speedmaster. Each set contained 23 stainless steel Speedmasters, of which 22 featured to logo of NASA’s most famous space missions. The first watch of this collection was made to closely resemble the very first Speedmaster, the famous reference CK 2915. The series was presented in a case made of the same white fabric used in spacesuits and also featured an additional, loose, calibre 1861. There were 40 of these sets produced. The patch watches were also available seperately, in limited series. The 1957 “Replica” was also available in regular production.
