I have had a Omega passed down to me from my grandfather, I think it is either 1950's or 1960's. It has not wording except Omega on the face. Any help would be greatly appreciated!

 

Hello,
Very similar to a calibre 620 around the same era (1953) Not entirely sure but I recommend you do some digging using this model as a starting point, better still, take it to a watch shop like Goldsmiths and they can take the back casing off to look at the mechanism more closely and any serial numbers to determine what model it is.

Kind regards, Jonathan.

 

Also similar to my cal 302 circa 1960



This one has a Florentine dial but otherwise similar



Edit - had a chance to open and its not a 302 but a 510

 

It is a CK 2900 Caliber 266/7

Thanks for the info, I just cannot find the exact model on the net. Although similar to the ones stated/shown above it's not the same. Also not very similar to the ck2900 as advised. I will take it to a local shop and see if they can figure it out, think we're on the right track looking at the 1950's though.
