Here the clock, mounted and revised, ready to be located again in the room 9 of the museum. The video shows the complete part of the mechanism.
The pendolum belonged to Beethoven is a late Empire style, i.e. the Napoleon style that is going towards a neoclassical style. Then, as it was in the Austrian Empire, most of the objects were slightly modified according to the country style.
The small bust above the clock (maybe fixed later, as there is a great use of glue that could mean a repair of it or a change of a previous decoration , maybe made of golden bronze) can be identified as a Minerva or is fixed in a later stage as a Cornelia, or an example of Roman Virtus, or a Santa Cecilia.
The marmour is just recolled in the edamel of the dial whereas all the other decorations are in gilded bronze.
