I'm looking at this Omega I found for sale.
Can anyone tell me about the authenticity of this old piece?

Sellers info:
Cal. 265
Serie no: 13139892
Year 1952
Crown and glass changed
Original dial
Case diameter 34mm

Thanks in advance.
Frans

 

Please send more pics like caseback, movement, etc.

 

Sorry no pics of the movement, but seller tells that it's recently serviced by a watchmaker (I heard only positive reviews about this well known watchmaker) and the caliber is 265.

 

Ref. 2639, refinished dial, original crown, IMHO.
