How do I clean marble cases?

Dust the stone regularly with a soft, dry cloth to prevent grime accumulation in carved recesses. Avoid harsh chemical cleaners or abrasive pads that can dull the polished surface. For stubborn marks, a damp cloth with mild soap is sufficient, followed immediately by thorough drying. Keep moisture away from the metal dial bezel and internal movement.

Why does my clock gain time?

Mechanical clocks are sensitive to temperature changes and minor shifts in placement that affect the pendulum or balance wheel. Regulating the movement usually involves adjusting a small nut on the pendulum or balance to alter its effective length. Small adjustments made over several days help the mechanism settle into a consistent beat. Patience is essential when bringing an antique movement to accurate timekeeping.

Are these clocks suitable for daily use?

These pieces function well as daily timekeepers provided they receive professional servicing and clean operating conditions. Placing them on a level surface ensures the escapement beats evenly. Periodic oiling by a horologist keeps the brass gears turning smoothly without excessive wear. Treat the winding and hand-setting mechanisms with care to preserve the original components.
