Hi,
Nice find! Incabloc is a good name, and you have a nice 1960's watch. You say it turns but does not wind up: that probably means that the spring is broken, but that's repairable.
Regards.
My son found a back to a 1920 pocket watch, I have looked in the general area, five times and we have not found the rest of the watch. Cool find, you got there. It took a licking and its still ticking.
Nice find. Have been at this many years and only found a few. One silver many years ago but the last one I got was toast. Some of the more knowledgeable folks on here have stated that if the back pops off more info will be on the inside. Since you already have ID from face about all it would tell you is possible date. I get a bigger kick out of that kind of stuff than most coins. Great find. Here is toasty one for ya.
