Help Identifying My Omega Constellation

Eliseo Gallo · Mar 2, 2025

Hello everyone,

I’m looking for help identifying my Omega watch as I have some details, but I’m not entirely sure of the exact model or year of production. This watch was my grandfather’s, and I would love to learn more about it. I hope someone with more experience with Omega watches can guide me.

Here are the details I have:

Brand: Omega
Model: Constellation (probably, due to the observatory symbol and five stars on the back)
Reference: 2852-7
Serial number: 15383408 (located on the movement)
Visible features:
- Silver stainless steel case with gold-tone accents
- Approximate diameter of 34-35 mm
- Automatic movement (likely Omega 501 or 505, though I'm not sure)
- I’m not completely sure if the strap is original, although it matches the design of the watch.

What I need:

Help confirming the year of production and the exact model.
Any additional information about the approximate value of this watch, as I’m interested in learning more about its history and possible value in the vintage watch market.
I also have some photos of the watch if anyone is interested in seeing them to help with the identification.

I really appreciate any help you can provide. Thanks in advance!

Hi,

the movement number dates the watch to around 1954

If you want an honest opinion on the condition?

Very bad condition:
Dial is badly repainted
Hands are in bad condition (if original at all, hard to tell)
Case is strongly overpolished
Bezel is missing
Wrong crown

Can't comment on the movement, pictures are too bad

So nearly no economic value IMO, sorry!

EDIT: "Exact model" Reference number is standing on the inner side of the caseback, should be 2652

While the above assesment may seem a bit harsh, it's the truth.
I'm not too familiar with Connies, but this one stood out to me as a basket case.

Back to real life though. It may be worth nothing to the casual buyer just after a watch, even less than nothing to a collector.
However, it's a family piece, therefore the value isn't in the watch, but in the memories it holds when looked at on your wrist.

Correct assessment, just two details: It’s a 2852, as mentioned by the OP. That’s the model reference.

And the 2852 was launched in 1956, so it’ll be from ca. 56-59.
