Video demonstration of a French mantle clock, c. 1810 with orrery
mounted to the top. The orrery is driven by the clockwork and can also be
demonstrated by a crank. The clock is unsigned and the orrery was probably
supplied by a third party as many makers including, Janvier, Baltazar,
Guiteau, Berthoud and others have clocks signed by them with this same
mechanism. The basic construction is common throughout, only details such as
engraved vs. enamel dialing or different dial bezels were supplied as
upgrades.
