A Very Rare Celestial Clock with a 24-Hour Dial by The Universum Clock Company, Boston, MA. SOLD

A very rare turn of the century celestial clock with both a 24-hour dial and a celestial calendar dial in a glazed mahogany case. The adapted tandem wind Seth Thomas movement is wound and set from the back. The mahogany case has applied engraved patinated plaques to the corners and across the bottom and a large brass ball above the dial that represents the sun. The plaques show different astronomical facts and events. The paneled back has a door that provides access to the movement which is necessary when reassembling the dials. The engraved aluminum time dial also carries a map of the northern hemisphere with the time zones included. The celestial dial has the planets, stars and constellations in red, green and black ink. As the two dials turn the sky is represented for each calendar day when observed from the northern hemisphere.
