Notes Watches with a wandering hour dial first appeared in the 17th century. In England, records indicate that they were often commissioned by the king to be presented to visitors or in recognition of loyal services to the country. It appears that the custom existed in Germany as well. Most German wandering hour watches feature portraits, often of Frederick I. Watches with such portraits were usually intended as gifts from the sovereign for another German wandering hour watch with the portrait of Frederick I, see the Lord Sandberg Collection, Antiquorum March 31, 2001, o. 11.
