This is accomplished by the solar hand riding the ecliptic rail as the sky map makes one revolution in 366 days, 23 hours 56 minutes per day, or a sidereal year, while the time movement keeps 24 hours a day 365 days a year. Lunar activity is represented by the moon hand. Sidereal time is indicated by the silvered S hand read against the eglomise twenty-four hour, Roman chapter, sidereal time dial which encloses 16 1/2 in. of visible sky map. The overall diameter of the planisphere sky map is 20 inches. A very similar clock, almost certainly by the same maker is in the collection of Her Majesty, The Queen at Buckingham Palace. See H. Cliffford Smith, The Complete History of Buckingham Palace: Its Furniture, Decoration & Treasures, London: Country Life Limited, Coronation Edition, pl. 300.An English planisphere clock, not to mention a wall clock, is extremely uncommon and seldom come to auction. Planisphere clocks that do appear at auction are nearly always in the form of Dutch tall case clocks 9 1/2 to 10 feet tall. See J. Zeeman, De Nederlandse Staande Klok, Amsterdam, 1977, pp. 465-487.
