Table clock movement by Grignion & Son, London, prior to 1784. 11 inch silvered dial with sunk seconds dial and steel hands. Signed 'Grignion & Son London' within a sunk cartouche. Fusee movement of 8 day duration with a deadbeat escapement and short pendulum, and maintaining power. The escapement gives impulse on one pallet only. Presented to the museum of the Worshipful Company of Clockmakers by John Grant in 1875.
Grignion and Son were formed of Daniel (1684–1773) and his son Thomas (1713–1784). The date of this clock with its apparently pioneering escapement is uncertain. Clockmakers' Museum No. 568.
