Op-shop ID?

The badly tarnished engraving on the case back leads me to believe the case might be gold filled, not solid karat gold alloy. The bracelet is not original to the watch, and has negligible effect on the value. To many collectors, the engraving on the case back detracts from the collectibility quite a bit. It might be said that anything is worth more to the owner than to anyone else! Perhaps you should service it, put a good quality leather strap on it, and keep it. In its present condition, it will not appeal to many collectors.
