This Apollo IX model commemorates the mission carried out between 3 and 13 March 1969 by James A.McDivitt, David R. Scott and Russel L. Schweickart.
Apollo 9 was the third crewed mission in the United States Apollo program and the first flight of the full Apollo spacecraft which included the two principle components: the command and service module (CSM), i.e. the mother ship, and the Lunar Module (LM). The mission was carried out to show that the crew could fly the Lunar Module independently and then dock it with the CSM again, as would be required tor the first crewed lunar landing 50 years ago.
This watch is truly out of this world!
