Stopped by an antique shop today and spotted an old swiss mechanical watch for cheap so I bought it. The dial says
I opened it up and it's says Den-Ro Swiss Import Co. The interesting part is the movement says "One 1 jewel unregegulated." Anyone ever seen a one jewel mechanical watch? I searched and didn't see anything but I'm a rookie so maybe someone with more knowledge can chime in... Lemme see if I can post some pics. Thanks!
