Historical significance - Straight Writing Speedmaster

Following the historic Apollo 11 Moon landing in July 1969, Omega introduced commemorative case-back designs celebrating the Speedmaster's role in NASA's space programme.

The early Straight Writing Speedmaster is particularly sought after by collectors for its distinctive case-back inscription.

Unlike later Speedmasters, where the commemorative wording follows a curved design, this version features the horizontal "The First Watch Worn on the Moon" lettering.

The internal case-back is correctly stamped ST 145.022-69, with the HF case-maker marking.

The watch houses Omega's celebrated calibre 861 manual-winding chronograph movement, introduced as the successor to the legendary calibre 321.

Condition

The watch presents attractively for its age, with expected signs of vintage wear to the stainless-steel case and bracelet.

The dial, bezel and hands have been preserved, retaining the character of an early 1970s Speedmaster.

Please refer carefully to the photographs, which form part of the description.

No original Omega presentation box is included.

Water resistance is not guaranteed due to the age of the watch.

A desirable early post-Moon Omega Speedmaster Professional, combining its original vintage appearance with the benefit of servicing and retained original components.

A wonderful opportunity for a Speedmaster enthusiast or vintage Omega collector.
