Hello,

This piece was given to us from my father-in-law whose mother purchased it from a jewelry store in Macau in 1965. It has been tough to gather information on it and was hoping this community could share their knowledge. I have the Omega certificate which shows the reference number as OG 129.71 and the mov. number as 19852615. I believe this is the serial number? I am not sure what "18K white cold case" refers to as this very much looks like a yellow gold watch. I believe it to be all original, but there is no omega stamp on the back of the face. The watch weighs 62 grams. I am scared to open it and do not have the tools to do so, but I think a serial number would be inside? Any info is appreciated. I do not believe it has ever been worn all but a few times. Thank you!

Brent

I have no doubt that the watch is legit, but I feel like maybe that certificate is for a different watch. An older one.

You're right, it's not the watch that belongs with that card, or vice versa. Could be 14K or 18K case and integral bracelet.

As a lady's watch, not much collector value. As an heirloom and something to wear, perhaps more. Find a watchmaker and have it opened and take pictures of the inside of the case and of the movement. More information will then flood your way.

Looks like a 750 stamp on back of bracelet clasp, meaning 18K.

Are you certain about the 1965 purchase date? Seems to be a bit later style.

Looking on the Omega web sight your reference # above doesn’t come up, where are you getting reference number from? And is it possible that the Omega certificate you have could be from another watch (since it’s showing white gold)? A picture of the inside of case back should show correct reference #.

Serial number will be on the movement. Given that the case appears to be solid gold, I would have a watchmaker open the case.

The papers don't match the watch. The watch, especially if the case test results match the hallmarks, is probably about 10 years younger than the paperwork. I'm inclined to consider it legit until proven otherwise as this is reminiscent of ladies watches made in the mid-70s. If a pawn shop or jeweler tests the case and bracelet and they DON'T come back as 18kt gold, the watch is not worth anything and not a legitimate Omega.

Papers say a white gold case..... and that’s not a white gold case watch.

It looks legit but 70s mid to late and my bet is a quartz movement inside

Wow, thanks for the great information. I'll definitely take it to have the case opened. I also need to talk to my father in law and see if there is another Omega that perhaps matches the paperwork. He's going through his Mom's house and finding all sorts of treasures. I'll follow up with a post once more info is known.

Hello! I have a few updates and photos. I have confirmed it is legit (like many of you have stated) and the movement number is 33873151 which puts it at 1971 apparently. There are also other descriptors which I do not know what the meanings are: "17 jewels", "adjusted to 21 positions", "Omega 620", and on the back side of the case is "8340 242" with other inscriptions. I find this all very interesting! Thank you in advance for any more info you can all provide me.

I love a good mechanical movement, how’s it going keeping time? Probably needs a service. And is iit just me or is it missing some screws?

so far so good with the time, works perfect. the watchmaker who opened it said it was serviced once from the scratch mark on the inside of the case.

The casing tabs aren't required as the movement is held in by the caseback, so no screws missing, or they are missing, but it doesn't matter.

The 18K case was made for Omega by Artisanor SA of Carouge, Geneva.

That's "adjusted to two (2) positions". Dial up and crown down.

The case number is stamped on the clasp it’s 711.1851. The 711 part sounds right for a ladies bracelet watch.
