A very rare wandering-hour pocket watch, maker William Knottesford. English circa 1670. Gold "wandering hour watches are most unusual, particularly when they come from the period prior to the introduction of the balance spring. In a letter to Norman dated 24/7/1984 Terence Camerer Cuss says about this watch "It is exceptionally early for a wandering hour and maybe is the earliest". The gold dial of this example shows Diana in her grotto; Diana's nymphs were expected to be as chaste as the goddess herself. One of them, Callisto, was seduced by Jupiter who first disguised himself as Diana in order to gain the nymphs presence. Diana confronts Callisto, pointing accusingly. Callisto, her robes drawn back to show her unmistakable pregnancy, cringes in shame. The other nymphs register shame and disapproval. The inner case and the decorative pins to the skin-covered outer case are also gold. the movement has a verge escapement, fusee with chain drive. On the dial there is are no conventional hands, but the hour of the day appears on a circular disc that moves around a semi-circular aperture that has both the minutes and the quarters marked on seperate scales.
