An unusual rolling ball clock to the design by John Wilding
A Congreve rolling ball clock to the design by John Wilding, for the Constructional Serial published in the Horological Journal, Dec 1975 - Set 1976. This popular clock uses a fabricated skeletonised tilting table to make it lighter. The clock is surmounted by the triangular pediment supporting three dials for hours, minutes and half minutes, bordered by four ball and spire finials over four tapered steel columns flanking the pivoted table escapement, impulsing the single fusee movement. 41cm (16in) excluding the case and stand. The clock comes with a perpex case.
This clock has been working but due to the nature of the clock the timekeeping is not very accurate. These clocks also require a great deal of setting up to get them to work correctly.
