I just bought an old Eterna-Matic Sahida for my wife. It´s in a squared stainless steel casing and was sold to have a caliber 1446U. There is a number on the back reading 4537780.
As there seems very little information about this lady´s watch on the internet, maybe someone here can help providing me with details? I found only one picture of an Eterna-Matic in a case shaped like this (it was a golden one with date and was said to be from 1957 or so) and no infos about the caliber…
Looking forward to more infos, greets,
