Well its a model 6349 . Made in late 1978. It is gold plated with 20 microns and has a caliber 625 manual movement. It is not worth to much at this point. You don't state if it is running, but it can likely be repaired if it is not and certainly for far less then $600. Your best course is an independent watch maker for about $200.

 

Then once again I would find good watchmaker to do the work.

 

Womens watches do not bring as much as men's. Cleaned up and looking nice about $200 on a good day, less on a bad one.

 

Ah, hard to tell from photo. Then perhaps $300-400 You must always make that known if you sell it.

 

It may have something to do with the case maker , which is not Omega and probably the Dennison Watch Case Company ( they made cases for English Omegas, so it is legit). It could be a date marking or just a design. Please check back later as others may know.

 

Actually, the logos are engraved on the underside of the dial. "ZJ" or "JZ" must be the dial contractor. That part probably was made in Switzerland.

Not the first time that question has been asked without a good answer:
