I took a July 4th trip to visit some family in Virginia and walked away with a true gem. I was gifted my great grandfathers Juvenia Arithmo Calculator watch. I can't seem to get over it's beauty. He passed away 25 years ago and this had been tucked away for at least that long. Upon receiving I've looked up everything I could find on the piece(not much) but it's history is rather perculiar. Runs about +48spd so far. Looking to get it serviced soon. No intentions of selling but does anyone have a clue what it's worth? They are very hard to come by.
