Specialist note

Bofenschen was working in Paris from 1780 on the Rue St Honoré. He moved to Boulevard du Temple in 1810. According to Tardy, he also worked for Abraham Louis Breguet. The perpetual calendar work of this clock is drawn from that described by Moinet in his
Nouveau Traité Général d'Horlogerie, vol. II, ch. V, pl. XLIV, figs. 8 & 9. The very unusual escapement to demonstrate seconds from a half seconds pendulum has apparently never been described.
