Where should I place a heavy marble clock?

Support these pieces on a sturdy mantelpiece or heavy sideboard capable of bearing substantial marble and bronze weight. Keep them away from direct heat sources and sunlight to protect marble and enamel. Ensure the surface is completely level so the pendulum swings evenly and the escapement ticks in a steady beat.

How do I distinguish bronze from spelter?

Bronze feels heavier, sounds more resonant when tapped, and takes a deeper patination or fire gilt finish. Spelter is softer, shows lighter weight, and often reveals grey metal beneath worn paint. Magnification reveals the sharper chasing lines characteristic of bronze compared to the softer edges of moulded spelter.

What maintenance do these movements require?

Mechanical clocks benefit from professional cleaning and lubrication every few years to remove old oil and dust from pivots and gears. Keep the glass door closed to prevent dust accumulation on the dial. Moving the clock requires securing or removing the pendulum to protect the suspension spring from damage.
