Notes

This is one of the rare surviving 16th century watches with 'cloisonné' enamel dial.The stackfreed works by regulating the power from the mainspring. This is usually archieved by the action of the stackfreed spring on a cam mounted directly or indirectly to the barrel arbor. The constant change of the radius of the cam regulates the power transmitted to the wheel train. In this watch, the unusual shape of the stackfreed spring is an interesting example of the development of early German horology.
