Caliber 861 movement.
Superb tritium dial with a very nice patina on the indexes and hands.

Its original new Omega hesalite glass replaced for sale.

The case is mounted on a 1479 stainless steel bracelet without stretch and 812 endlinks.

This tritium Speedmaster is one of the first production models of the reference 3590.50 (coming just after the Long S&R gimbals). A real must-have in its tritium version.

The Omega Speedmaster was the first chronograph to visit the moon. NASA had previously conducted all the necessary tests to determine the watch's resistance to space flight.
