|This clock has a pioneering and unique escapement mechanism, invented in the early 1700s by Grignion. This can be best described as a dead beat escapement with impulse on alternate oscillations , one pallet giving impulse while the other locks the escape wheel. Designed to beat half seconds, it has seconds, hour and minute hands with the movement mounted in pivot bearings, and an electrical epicyclic rewind which runs unattended for months. The clock case is 18" wide and can be displayed on a shelf. The original can be seen in working condition in the Worshipful Company of Clockmakers Museum at the Guildhall, City of London.
