A brass and glass wonder! The 15 jewel 8-day movement runs quite accurately and is a pleasure to look at. Dimensions are length: 15,5 cm, width: 10,3 and height 5 cm. These desk accessories were popular luxurious artifacts in the fifties and sixties. The present day Swiza company history page states that in 1959 this movement saw light:
The launch of the first-ever 8-day, 15-jewel mechanical movement – an exclusive SWIZA® innovation – led to the firm’s significant international development.
We therefore assume that the production date of this Swiza is 1959 or into the sixties.
