Vintage Constellation Pie Pan

Hi. How much is the seller asking for this?

That dial wouldn’t be considered a pie pan and the watch should keep better time if it was just serviced. I presume the dealer is asking considerably more than the watch is worth.

This watch has been online for months if not a year plus. There are reasons it hasn’t sold yet. @Dan S just explained why.

If a vintage watch has been properly serviced and is in good condition, the variation in timekeeping should be better than -20 to +40!

Nice photos but I don’t think that watch will look anywhere near as nice in real life. I agree it’s a bit shagged out.

OP, it’s always better to say in your overview what the asking price is and also what your research has shown. Even as a beginner you can research prices.

There are some strange things in the movement...



On the rotor, there are two sections I've added arrows to that have clearly been modified by someone. Also one hole on the automatic bridge is not round - both these are very strange and I see no reason for these modifications to be made.

As you can see the plating on the base movement is in very poor shape, where the automatic bridge the plating is intact. Back when these were in production, Omega sold the complete automatic winding unit as one replacement part, ready to install, so at some stage it's very likely that this watch had the entire automatic winding unit replaced, which is why the plating on that is in much better condition.

This goes to the claim they are making that all the movement parts are original. The added claim that no parts were replaced during service is stated as if that is a good thing - it is not. There's no way that watch movement gets this shagged out without having been used a lot, and if there were original parts in there they would be worn out. Maybe they are and that's why the timekeeping is so bad....

To be specific with one example you can see on the rotor that it has wear here at the red arrow:



This wear happens when the rotor pinion wears out, and the rotor flops around enough to scrape on the inside of the case back. If they didn't replace any parts, that means they didn't fix this issue, so the automatic winding will not be efficient, and the wear particles from this rotor continuing to scrape will all end up in the movement.

For me on many levels this watch is a hard pass...

I’d suggest posting in the want to buy forum to see if anyone can help. eBay may have one available as well, I as them pop up from time to time, but I’m not sure I’ve seen only the medallion, just the full caseback

No problem. Nice watch, very surprising someone was just going to toss it

Be careful. Genuine medallions are very hard to find and there are fakes out there.
The best bet is often to try and find a spare case back and salvage it from there.

I don’t think Omega ever sold the medallions separately.

These medallions were made from very thin 14K gold and were hollow. Very difficult to remove with damaging.

So if you see one on eBay, it is a fake, maybe cast from a real one.

This exactly, the only way to solve this problem is a replacement 2648 case back with yellow gold medallion....and these are very hard to find
