Omega

• cal. 321 copper-finished lever movement, mono-metallic compensation balance, 17 jewels, metal dust cover • black dial, luminescent baton indexes, luminescent alpha hands, three subsidiary dials indicating constant seconds, 12-hour and 30-minute register • large tonneau-shaped water-resistant-type case with faded black bezel calibrated for tachometer, two round chronograph pushers in the band, downturned lugs, screw back • case, dial and movement signed • with a stainless steel Omega bracelet

The movement is running, however it may require service soon. The movement is numbered cal 321and 19583552. The luminescence has faded somewhat on the indexes, as had the paint on the hands for the subsidiary dials and chronograph indicator. The bezel has faded to a light gray color, and there are some chips to the outer edge. The case shows scuffs from wear throughout, and the bracelet is slightly stretched.

Important Notice regarding importation into the United States of Rolex watches

This model, Ref. 105.002, was first released in 1960, the same year as Ref. 2998, an example of which is featured in the following lot. Both models feature the cal. 321 movement, the early case with the flat lugs and no crown-guard and no 'Professional' signature. As such, they are known as 'pre-pro' models. The main difference between the two is the subsidiary hands on this model are straight lines, while the subsidiary hands on the Ref. 2998 are alpha hands.

Because of the similarity between the two models, it is now unclear as to whether it was this model or the Ref. 2998 that American astronaut Wally Schirra wore during his October 1962 flight on Mercury 8, making it the first time an Omega was used in space.

In the succeeding years, Omega would make an indelible mark on the world of horology as the watch worn to the moon. After extensive tests, the Speedmaster would be chosen to be the watch worn by every astronaut through the end of the Apollo program.
