This coach clock was probably not made in Paris, it is, however, remarkable in more than one way. A master of this name is not recorded anywhere. Most likely the timepiece was created by a German master by the name of Johann or Johannes Kiele, who engraved his signature on the movement in mirror writing. The clock also features a very rare, one-week power reserve.
