Hey guys! Need some help identifying this watch. Yes it’s a family heirloom, no, I don’t care how much it is worth. No money in the world would make me sell it. It was my grandfather’s and it means the world to me. My father used it on his wedding day and so did I and my brother as well! Unfortunately we have no documents or the backstory of the watch and would love to know more. If you have any information it would be amazing. I only know it’s probably pre 50s, gold, bought during a time of my country’s dictarctorship (it has the typical customs stamp). Thank you in advance!

EDIT: forgot to mention it’s manual wind

Perhaps you can have it opened and show the inside.

Looks like an early 50s bumper automatic (does it bump if you gently shake/move it)? Or it could be manual wind. Lovely condition!

It would probably contain a 30mm calibre of the 26x series . The bracelet is an add-on, not Omega but still valuable as gold weight. Remains to be seen if the case is of “national production” or branded Omega inside. It was common in some countries in the 50s, to re-case steel watches in a new gold one. The gold mark on the back would hint that this is the case.

It looks like if there are markings on the top-left lug, which is usually seen with watches for the Portuguese market.

AS @Franco says, the outside hallmark means that it is not a Swiss case - I would have thought that it had been produced in the OP's country, but since there is an import stamp, I guess it is from a different country all together?

@syox do your family have connections to a different part of the world? Perhaps someone did some international travel?

Automatics of that era (all automatic Omegas?) are marked as such on the dial 😀

To me it looks kind of hebrew in that caseback marking. Israelian Import Stamp maybe?

Israeli hallmarks are different:

Wow you’re spot on. Thank you for your reply. I’m actually Portuguese! I’m trying to decipher the markings in the back but can’t make it. From what I understood from my grandma the watch was probably bought in the late 40s, but maybe it was early 50s as you suggested!

If it’s late 40s I’d say looking at the design it’s going to be no earlier than around 48 or 49. If you’re able to go to a jewellers and ask them to pop the back open, then a photo of the movement and inside caseback (so we can see serial and case ref) will tell a lot more.

Aproveite seu relógio e faça a manutenção, durará muitos anos no seu pulso ....

Strongly advise to get it serviced (only ultrasonic cleaning of case and bracelet, dismantle movement, wash the parts, reassemble and regulate).
Go to an independent, not at Omega dealer. In the occasion ask to take pictures of the movement and inside back. And, if you have a macro lens, take a picture of the marks (like this but in focus).

The hallmark actually says 19K, not 18K. That would be 80% gold, instead of 75% gold for 18K.



I’ve never seen an Omega made case at more than 18K purity. I believe this case could have been made either in Portugal or imported from South America (Argentina or Brazil).

There’s not much I can say about the movement without pictures. The dial is in excellent condition for a 70 year old watch.

Hope this helps,

Ok, that's completely boss! How a gold watch can be so discreet and classy is beyond me but you sure pulled it off in style. Those pics actually made me happy!

Odd to see proof marks on top of the lugs. OP hurry up and get the case opened up! 😁
