A good example of a high quality polished Belgium slate bell striking mantel clock with a visible Brocot escapement. The rectangular case has grey variegated marble sides and an engraved molding front. It has a thick bevel edge glass in a brass bezel and a two piece enamel dial that exposes the working visible Brocot escapement. The 8 day movement strikes the hours and halves on a bell and was made by Japy Frere and has their 1853 medal stamp. The clock comes complete with keys and an instruction/running video clip.
