Hebdomas - Unknown - 1970-1979

Very rare pocket and desk vintage Hebdomas "8 Days", characterized by a porcelain dial with Arabic numerals and a visible balance wheel at the lower part. The timepiece is designed to run for eight days on a single winding and is Swiss-made. These models are often fitted with cases in gold- or silver-plated metal and can date from the early 20th century up to the 1970s. To provide you with a more precise estimate of its value or production year, you could send me a photo of the back or the internal mechanism; as you can see in the photos there is a small crack.
