SOLD 1966 Omega Speedmaster 105.012 cal. 321 Pre-Moon

Up for grabs is an Omega Speedmaster Professional

105.012 reference pre-moon with cal. 321 movement

249524XX serial number circa 1966 

Very good condition without major dings, dents or deep scratches. Does not appear to have been polished much in its life. Very nice and defined lugs. 

Watch is presented as found with all the dust, grime, dirt, and case patina. There is no corrosion or rust on case. I am more than happy to clean it off before shipping to you, but its available as found. 

Dial is excellent step with applied logo. Very attractive yellow patina on all plots is original. Hands appear to be original. Dial is scratch and damage free. Any imperfections you see in pictures are small scratches on the crystal.

Caseback’s Seamonster is worn down from use, but still partially visible. Caseback is stamped 105.012 – 66 and CB. CB stands for Central Boites, and these cases were made with a bevel on top of lugs, which is usually polished down over the years and hard to see. This case shows it clearly on each lug.

Pushers and crown are original with pushers being short, press-fit and skinny logo crown.  

Bezel insert has been replaced at some point. 

Watch runs well, with plenty of amplitude, but service history is not known nor documented. Chronograph runs and resets to zero. The hour totalizer is stuck and does not reset or advance. 

Watch comes on unworn vintage leather strap with steel buckle. 

No boxes, papers, or other accessories. 

This is not a perfect example, but it is a very original example with exception of bezel.
