Omega Constellation 168.005

For a seller to casually swap parts like this would also make me think twice about buying from them

Couldn't agree more

I’m not sure how pic 4 can be ‘wrong’ when the new pic is the same movt with a swapped bridge.

Yeah it's really weird...he has a top score on Tradera so I wanted to give him the benefit of a doubt. But I guess it's to much of a red flag to commit 1500-2000 dollars.

Allright so to change the bridge one have to change the rotor as well. At least that makes sense. What doesn't make sense is that he says in the add that the last owner serviced it some time ago, that it runs well but there are no papers. Why would he then accidentally remove the correct bridge? Or did he not realise that it was the wrong one when he first took the pic and after I wrote happened to have the correct bridge laying around?

I guess I will never be confident enough to buy any vintage watch online for that kind of money.
Thanks again! At least I learn some new things from each post.

Regarding servicing.
The regulator is jammed hard over - so I would probably take the servicing comment with a pinch of salt too.
Best to avoid me thinks.

In less than 12 hours we will know how much it is "worth". I just noticed that the back of the lugs don't seem to match? But I can't imagine why he would change the whole case? In the first pic the lug to the right has numbers on it. This doesn't match the second pics lug to the left (watch turned 180 degrees), no numbers present as far as i can't tell. There is more dirt/gold/rust on the back of the lugs in pic 2.
