It depends on how early I guess? No issues getting an extract on my 105.003 last fall.
As no chronograph movement was made in house by Omega between the early 30's and up to modern times I am surprised why just these from the 50's should give them problems?

 

Full match.

 

unless very rare exceptions, for which they found new information, no extract delivered for any 320- or 321-caliber based Omega until about 20.525.

 

The case ref is -65 so I guess Omega assembled a few some years later?

 

yes, they probably oredered A LOT of cases in 1965, the most intriguing being that the case maker remains unknown and only made cases 105.003-65 to my knowledge

 

exactly. They have not been strict enough for years and one should consider old extract for pre-20.525 with great caution

 

hey, that's interesting! I just looked at my 105003-65 and it was produced in 1967!!! Plus is has movement number from even later !! 25.4 mil! delivered to Venezuela!

 

Looks like Omega, or rather, Lemania, did not assembled the watches sequentially.

Here is my extract, 105003-65 but really , the production year was 1967! And not only that, movement number is later than yours but production of this watch was a few months before yours... intrigue.

 

As far as I know, Lemania delivered the movements to Omega in batches. Omega cased them in Bienne. This explains it well as the guys fetching a new batch of movements from the Omega warehouse would mix and match.

 

HI. Just acquired my first vintage speedy. I went to the Omega website for an extract and it said service not available to US? Am i missing something. I would like an abstract.
