Typology: Vintage chronograph
Year: 1966

Omega Speedmaster "Pre-Moon" 



The 105.012 Speedmaster was the only version to have been confirmed as landing on the moon – the first watch on the moon on the arm of Neil Armstrong. It was also the first Speedy to feature the text ‘PROFESSIONAL’ on the dial and the first to have the iconic asymmetrical lugs on the case. On this example the original ‘Dot over 90’ (DON) 500-base bezel.

The ST 105.012, on the other hand (NASA reference 6126) was chosen for the Apollo missions without the need for new tests.


In 1966, “CB” cases were made by Le Centrale Boîtes of Bien, while the majority of cases for the 105.012 were produced by Huguenin Fréres, who also made cases for previous reference Speedmaster timepieces. There were noticeable differences between both cases. The CB case has lugs that have an additional polishing plane on the upper side of the lugs. The CB case also has a small line between polishing planes on the lugs, which is not present in the HF cases.


The conditions of this Speedy are exciting. The CB case is untouched and unpolished, in moving condition, with still all the original shapes and geometries.

The set is incredible. The outer box, box, red omega tag, silver omega tag, sealing wax tag and warranty ( in white ) dated 1967.
