How do I wind a french pendulum mantel clock?

Most of these timepieces use a key inserted into winding holes on the enamel dial to tension the spring-driven or weight-driven movement. Care must be taken not to over-wind the mechanism. Moving the hands should be done slowly and strictly in accordance with the manufacturer instructions to avoid damaging the escapement.

What is a mercury pendulum?

A mercury pendulum contains glass tubes filled with liquid mercury designed to counteract temperature fluctuations that alter pendulum length. This engineering kept the clock accurate across changing seasons. These pendulums are typically found in better quality four-glass architectural models from the nineteenth century.

How do I tell an Empire style clock apart from a Rococo one?

Empire style clocks rely on classical symmetry, architectural columns, military motifs, and figures derived from Greek and Roman mythology.

Where should I place a heavy marble mantel clock?
