I have a 1960 Bull's Eye pocket watch. Its been sitting in a drawer for many years and probably could use a cleaning and oiling. The pocket watch has no jewels that I can see. The watch runs great. What would be a good oil to use on a watch that has no jewels? Would a synthetic with Teflon work? I read that slick 50 synthetic has Teflon and works well as a spring lube. The theory being the Teflon would act as bearings since no jewels are present. ?
