A friend asked me if I could find out anything about this watch that belonged to her mother. It is a Juvenia with a very unusual case design. I had not heard of the brand, but I did Google the company, which appears to have been in (continuous!) operation since 1860 and is based in La Chaux-de-Fonds, and presently owned by a Hong Kong based holding company.
I wound it and it appears to be working at some level, but if it is to be worn, would certainly need to be serviced. I doubt it is worth much, but could have family keepsake value. Anyone here who might have any further information on this one?
