Antique Pocket Watch Dials

Does anyone know anything about antique pocket watches?

I have a pocket watch that was given to me I can not identify. This is an antique pocket watch engraved with a gray area surrounding the figures in bold. At the bottom of the pendulum, the dial second hand is covering the 6 completely and cutting a piece of 5 and 7. The back of the watch is worn, but it has an engraving of lines and a model that looks a bit like mirror. There is nothing written on the other shows the figures. Could someone please let me know more about this watch! Thank you, I've just noticed the name of the watch is a trademark of Illinois, if that helps.

Debawiggi Hey, You should be able to find the watch or contact a person of one of these sites. Good luck.
