I have a Zodiac Hermetic I got from my grandfather, it's still working, I just want to know more about it.
The numbers on the back are 355196
I would appreciate any help!
That is a dress watch from the very late 40's or the very early 50s. Would make a nice family heirloom!
Be sure to read this before wearing it though.
