Dumb question I know but anyway, I must be having really bad luck. I got my 2nd watch from eBay- this time a 30's Ingrham " Sentinel" pocket watch with nice art deco in the mail. The watch doesn't run. It just starts then stops. Thus probably in need of a cleaning. This is similar to a Westclox in that its a low-cost, mass-manufactured American watch. I removed the back and there are 3 screws holding the movement together. I didn't touch anything. There was no obvious means to remove the stem. I'll take pics later. But anyway, I assume these too can be oiled and lubed like any other watch?
