How do I wind an eight day mantel clock?

Use the correct winding key to turn the arbours slowly until you feel firm resistance, taking care not to overwind the spring. Most movements require a full turn on both the time and strike sides once a week. Keep the key straight and steady during winding to avoid damaging the delicate square shafts connected to the mainspring barrels.

Why does my clock gain or lose time?

Variations in timekeeping usually stem from temperature changes or an out-of-beat escapement rather than a failing movement. Adjusting the small nut at the base of the pendulum bob will speed up or slow down the swing. Ensure the heavy stone case sits on a completely level surface so the pendulum swings with an even, symmetrical beat.

How do I tell an 1860 clock from an 1890 one?

Earlier pieces from the mid-nineteenth century tend to use heavier solid marble or slate blocks with restrained bronze mounts and traditional enamel dials. Later nineteenth-century examples frequently incorporate mixed stones, faux finishes, or lighter architectural proportions. Nail down the period by checking the movement backplate for maker signatures, serial numbers, and French foundry stamps.

Where should I place a heavy marble clock?

Select a sturdy mantelpiece, sideboard, or pier table capable of supporting significant stone weight without sagging. The surface must be completely rigid to prevent vibrations from disrupting the pendulum. Avoid placing the clock in direct sunlight or near active heat sources, which can dry out lubricants and discolour sensitive marble surfaces over time.
