OMEGA Constellation 1683004 - Expert eyes - condition, dial, authenticity & any red flags?

Hi everyone,

I’m considering an Omega Constellation “Pie Pan” and would really value your expert opinions before I move forward.

What I know so far

Reference: 1683004 (french case)

Caliber / movement no.: 561

Case material: solid gold - I can see hallmarks on the case, but I’m not a specialist.

My initial assessment
Overall it looks decent to me, except for the dial: there’s visible spotting/aging. Do you think a careful professional cleaning could improve it, or is it likely too far gone and better left as-is to avoid damage?


Small doubt about the “SWISS MADE” text
On most photos the “SWISS MADE” at 6 o’clock is barely (or not) visible, yet on the last photo it appears very faintly. Could this simply be angle/lighting and acrylic-crystal distortion, grime at the dial edge, or is it a potential redial/retouch where part of the print has faded or been polished away? I’d appreciate your take.


Questions for the experts 😉

Authenticity/originality: Do the dial, hands, markers, crown and crystal look correct for this reference? Any signs of a redial or replaced parts?

Material: Does the box look like a true gold dial or just gold-colored?

Condition red flags: From the photos, do you see over-polishing, moisture damage, rotor wear, corrosion, or anything else that should give me pause?




Thanks so much for your time and any professional insight you can share. I’ve tried to research as much as I can, but I’m not an expert, and I really appreciate the guidance!

Thank you, @Peemacgee.


I’m not a professional, so just to understand: if it’s polished, what’s the actual issue—purely aesthetic?
You’re right, it’s patinated. Is it feasible to clean/restore it while keeping some of the patina?
Also, is €3,000 a fair price?

Maybe last question, is it easy to find a similar model ? I'm a big fan, and I would like to find one. I searched and it's not easy, I can wait few months of course.

Thanks again,
Vincent

This one’s the same as your watch - rose gold, 18kt: Omega Constellation 18ct Pink Gold 1683004 (same no. as on the inside of your caseback too). And same calibre (561) as you point out. Your serial number puts it at 1966 Omega serial number decoder. Date an Omega by serial number, calibre or model. Can’t see the crown fully but it looks like the right one. There are a few scratch marks on the rotor, but it doesn’t look as if they’re from wear (there aren’t any corresponding wear marks on the inside of the caseback.) Not sure if the black caseback seal/gasket is missing?

So it looks good to me from that POV. It does however look like it’s been polished quite a bit - note the rounded lugs (bent?) and case; they would have had sharper edges when new. Depends how much that bothers you. To me the dial looks like honest and original. But you might want to try a MOY check. Along with the spotting/patina, there may have been be a bit of water ingress around 5-6 O’clock that’s left a stain. Difficult to tell. Doesn’t look as if the movement’s been affected though. Again, depends on how much it bothers you. If it doesn’t, I wouldn’t get the dial restored unless you want it looking like new. But doing so would devalue the watch if you ever plan on selling it on. As you point out, you might not be able to see Swiss Made because of the distortion through the crystal. Hands and indices look good. Those look like original black onyx inserts, but it’s difficult to see. I think it’s a nice honest watch! Other members more expert than I will have a POV too. Good luck with it.

'MOY' test and sharp lug and case facets for reference 😁

Agreed, price is bonkers - honest though it is.

HI, i recently bought these in a auction. can somebody tell me more about them. they are pretty small in size so I'm pretty sure they are for women's watch. which model does it belong too? are the worth anything?/

Hello,

You should start a different thread about this.
