The Speedmaster

Introduced in 1957, the Speedmaster is the chronograph worn on the Moon in 1969. Later Speedmasters such as the Speedmaster Date use an automatic chronograph movement; the ref. 3511.50 runs on the Omega calibre 1155, based on the Valjoux 7750.

Reference numbers

Omega case backs and inner case backs carry reference numbers that identify the model and period. Each listing gives the reference.
