Vintage Allemann 8 Day Desk Clock. I would assume this is from the mid 20th Century, 1950s. The clock measures 9cm H x 3cm D x 6.5cm W. It weighs  220 grammes. The  dial reads "Allemann 8 Swiss". The rear reads "316770".  The clock winds, sets and works properly keeping time . The alarm also sets and works properly.
