Advice on a 168.0056 cal. 1011- marks on rotor

A typical scenario with many vintage watches with certain types of gaskets. Is it my imagination, or is this common to Omegas of the vintage of the subject watch? The gasket tends to liquify and turn to goop. That appears to be the situation with the subject watch! Some of that goop appears to have spilled over onto the rotor, and some handy man appears to have made a hash of trying to clean off the rotor! Moreover, he has made no attempt whatever to remove the spoiled gasket from the case! Aside from this, your pictures are so awful, it is difficult to comment any further on the condition of the watch.

The seller tried to do a “touch up” to improve the appearance to entrap a buyer. He did a shite job, and only touched the surface. One can but wonder if he used some kind of abrasive to clean off the worst of the goop. Whether he used a solvent or an abrasive (or whatever), there will no doubt be residue in the movement. So, if you buy it, you’ll be in for significant expense to finish what he started. Depending where you live, you’ll likely spend $300 to $400 plus necessary parts. So add that to the purchase price and decide if you’re comfortable with that. The watch is probably 40 to 50 years old, and from the evidence I see, it will be necessary to service it. But don’t consider sending it to Omega. By the way, this watch was made during an era before Swatch bought Omega, and generally, it is not considered a very collectible specimen. I’d suggest giving it a pass.
