One was a demonstrator watch:
The other was a sample watch:
The sample watch had the grey leather half band on one side with a hole in the end. I always thought it was meant to be a way of hanging it on a display. The demo watch didn't have a band, but maybe it originally had a plastic one.
Bill, those two watches had distinctively different looks. Any idea of age? I would guess the demo watch to be around 1958ish... not sure about the sample one.
