Hello everyone! I want to buy a female omega with this reference 511.90003 but looking on the website omega found nothing about this reference. Can anyone tell me if it is normal? Sorry for the question but I'm ' just studing' vintage omega : -D . I can not post the photo . Thank you so much for the help they give me !
Lots of references do not appear in the Omega database. The watch in your photos is genuine probably 1980s.
