Passemant astronomical clock

[1] It is displayed in the Salon de la pendule in the petit appartement du roi on the first floor of Versailles, France.

[2] The clock is an exceptional rococo work over 2 metres (6 ft 7 in) in height, crowned with a moving celestial sphere.

[2] The clock mechanism was designed by engineer Claude-Siméon Passemant (1702–1769) and executed by the clockmaker Louis Dauthiau (1730–1809).

After being reviewed and approved by the French Academy of Sciences in August 1749, the clock was presented to Louis XV in Choisy by the duc de Chaulnes on 7 September 1750.

The fact that it was placed in the Salon de la pendule demonstrates the interest that Louis XV had in the mechanical arts through clockmaking.
