I received this watch from a family friend, it belonged to her husband who passed away in the 1970's. I wound it and all the features seem to work; date, hour, minute, second, stopwatch.
I'd like to learn more about it, but have had trouble finding any information about Gubelin watches online. I understand they're primarily in the jewelry business and sometimes partners with watchmakers.
I'd also appreciate any advise on where to have it appraised for insurance purposes.
