Description

The Omega Speedmaster Professional is perhaps the most iconic chronograph ever made. Known worldwide as the “Moonwatch,” it was flight-qualified by NASA and famously worn on all manned space missions, including the Apollo 11 moon landing in 1969.

This reference, the 3570.50, features the classic design that enthusiasts cherish: a black dial with white markers and hands, triple sub-register layout, and a Hesalite crystal. The engraved caseback proudly declares its historic role: “Flight-Qualified by NASA for All Manned Space Missions – The First Watch Worn on the Moon.”

The 42mm stainless steel case houses the hand-wound calibre 1861, a direct descendant of the legendary calibre 321 used in the Speedmasters that accompanied astronauts to the Moon.

This example, from 2005, remains in strong condition with its original bracelet and comes as a complete set — a highly desirable feature for collectors.

A Short History of the Omega Speedmaster
