Speedmaster Professional Moonwatch

The Speedmaster was introduced in 1957 as a racing chronograph and became the most famous watch in history when it was selected by NASA for the Apollo programme after surviving a brutal battery of tests that no other chronograph could pass. Buzz Aldrin wore a Speedmaster on the surface of the moon during Apollo 11 in July 1969 — a fact that has defined the watch's identity ever since. The Moonwatch designation specifically refers to the hand-wound, hesalite-crystal configuration that most closely follows the specification of the watches that flew to the moon. The current production Moonwatch maintains the essential character — same case shape, same tachymeter bezel, same three-register dial — while incorporating a modern co-axial movement.

The Omega Speedmaster ref. 3870.50.31 was in production from 1996 to 2014, as the alligator strap version of the classic Speedmaster Professional. It features a stainless steel case with closed caseback and a hesalite crystal. The alligator strap is fitted with a folding clasp.
