Help What is it?

Hi every ONE here,


I´m looking for some help. My Grandfathers Watch I Recived last week.
I can´t find anything about the Modellname or the specs. the movement is a 620, handwound.
The watch is 750 Solid Gold and the warranty Card is from 1975 the Ref. BA 311 7057 makes kind of sense:
BA for solid Gold, 3 for Mans Watch, 1 for manual movement, 1 for not water proof.
So far so good, but the rest is kind of blury.
At the Omega Vintage page is no such reference (7057), the request by mail was also not really helpful.
Maybe one of you has a idea which model it is and which origin it has in the long Omega History.

Well, it is what it is - these were most likely marketed without a model name (common practise) and it's an 18ct men's watch with a cal. 620.

What specifications are you looking for? The appr. year of production can be found by looking up the movement serial number.

Welcome to OF, by the way 😀

Year of Production is clear and also that this watch was not assambled in Swiss.
According Omaga, this movement and housing was suplied separately by Omega to the country of destination.

I wolud like to know to which category it belongs de Ville, or Constellation, or something else?
No Model Name? not even a nickname or an synonyme which is used in the Omega Community?

Yep, exactly.
