II · The line

Speedmaster Calibre

Omega launched the Speedmaster in 1957 as a chronograph. Its association with NASA and the 1969 lunar landing later gave the Moonwatch branch a distinctive place in space-exploration history.

III

The chronograph

A chronograph is a stopwatch built into the watch. On most models one pusher starts and stops it and another sets it back to zero, while the time of day runs on regardless. The counters on the dial add up the elapsed minutes and, on many models, the hours.

IV · The manufacture

Omega since 1848

Louis Brandt opened the workshop from which Omega developed in Switzerland in 1848. His sons introduced the 19-ligne Omega caliber in 1894, giving the future brand its name. The company adopted the Omega name in 1903. Omega began its work as Olympic Games timekeeper in 1932. Since 1965, the Speedmaster has accompanied NASA’s crewed missions, including the lunar landings. A new technical chapter began with the commercial introduction of the Co-Axial escapement in 1999. Master Chronometer certification became part of that development in 2015. Today Omega belongs to Swatch Group and continues Swiss watch production, with its home in Biel/Bienne.

V · Ownership

Wearing and caring

  1. 1

    A hand-wound watch is wound with the crown, ideally at the same time every day, until you feel resistance. Never force it past that point.

  2. 2

    Water resistance up to 50 m means splashes and rain. Do not swim or shower with it.

  3. 3

    Have the movement serviced every few years by the brand's own service or an authorised watchmaker.
