Why are they kept under glass domes?

The open framework leaves every pivot, wheel, and pinion completely unprotected from airborne dust and atmospheric moisture. A glass dome acts as a clear barrier that preserves the polished brass surfaces without hiding the mechanism from view. Most traditional examples were supplied with these domes to ensure the delicate escapement functioned smoothly between professional cleanings. Removing the cover requires careful lifting using both hands to clear the tall brass finials.

How do French and English skeleton clocks differ?

English examples often feature robust brass plate designs and fusee movements built for extended running times. They frequently sit on heavy marble or ebonised wooden bases beneath tall oval or round glass shades. French variations frequently incorporate four glass mantel designs or delicate miniature travel movements with passing strikes or pull alarms. The stylistic flourishes lean towards decorative gilt-brass framing and lighter overall proportions.

Can I leave a skeleton clock running continuously?

Regular running is generally beneficial for mechanical clocks, provided the movement has been recently cleaned and oiled by a professional conservator. Continuous operation distributes the lubricants evenly across the steel pivots and brass bushings. If the clock is transported or left idle for extended periods, let the power run down completely before moving it. Ensure the timepiece rests on a stable, level surface to keep the pendulum or balance wheel beating evenly.
