HAYOT Á ARGENTIN. An early small French alarm lantern clock, c. 1700. The brass case is dominated by an engraved dial with a rather narrow chapter ring incorporating a ‘lambrequin’ with the maker’s name. There is a pierced and engraved ‘Satyr-head’ front fret, plain side doors and hoop-and-spur suspension. The chapter ring has Roman hour, half-hour and quarter divisions and a blued-steel hour hand of which the tail is used to set the alarm time on the large Arabic alarm disc with engraved centre. The weight-driven, day-going movement is made of steel and brass and has verge escapement with a short pendulum. • Height: 24 cm; width 10.5 cm. • Literature: Tardy, ‘Dictionnaire des horlogers français’, Paris, 1971, p. 293.
