The mahogany case, in unaltered original condition, has an overhanging cornice with veneered panels above a door with carved split balusters. The columns frames a mirror panel and a "mica" decorated tin dial mat. The mirrored door conceals an eight day striking movement with an eagle form pendulum bob. The interior backboard is lined with period wall paper and features a superb early Asa Munger label printed by Richard Oliphant.
