Louis Thouverez, Paris, France, c. 1785. Dial is signed Thouverez h[orlo]jer From his highness M. {on signueu} r Duke of Orleans. Louis Thouverez is referred to in Baille's Watchmakers and Clockmaker's of the World, p. 313 as Master 1788-1825. Single train great wheel with rafter frame design. The great wheel is seven inches in diameter with crossings being of 'Y' formation. Pinwheel escapement, gridiron, compensated 1/2 second pendulum on knife-edge suspension.

Upper dial with center seconds hand. Left hand dial showing date, day of week and its zodiacal sign. Right hand dial indicating the months, their zodiac sign and the seasons. White marble base with putti in bacchanal scene frieze on front and science attributions, telescope and thermometer on sides.

The clock was made about 1790 for the Duke of Orleans who was known as  'Philipe Egalite' because of his liberal tendencies. As leader of the liberals and a Jacobin, the Duke of Orleans voted in January 1793 for the death of his cousin Louis XVI and subsequently followed him to the guillotine in November 1793, just a month after the King's wife, Marie Antoinette met the same fate. His eldest son became King of France, as Louis Phillipe, in 1830 and, when later deposed came to England, where he died.

The Duke of Orleans was an avid collector of skeleton clocks and may have also been the one who commissioned a large and rare clock by Ferdinand Berthoud.

There is a hatchway in the rear of the pendulum bob.

Inside is a compartment that is filled with lead beads. I have never seen this arrangement before. The interesting thing is that the compartment is relatively small in comparison to the overall size and mass of the bob; almost as if it was being used to 'trim' the mass of the bob. Theoretically this should not have any effect on the operation of the pendulum.
