Recently acquired and wanting to know more information about it. It measures 34 mm across the case.
I am curious about the date of manufacture, any special facts and a estimate of value.

 

Hi Greg,
23 mil serial dates the watch to around 1966
Dial and hands look very good movement seems to be OK also
Lugs maybe a bit too rounded by polishing, caseback aslo. Crown doesn't seem to have the right dimensions.
Is the watch SS or gold plated? Is the braclet golden ("20 Mirons")?
Braclet end links are not original and could be more accurate in fitting.
