1. there are some doubt as to this watch`s originality !!
In just 20 years two watches have been registered : one is reported here, the second is on K.KNIRIM’s book ( p.435 ) .
2. Gustonia could not be found in any list of Swiss or German producers .
It was, however , decided to list it in the “ D.H.” list in the event that
some other Gustonia were to be found .
