How do I wind the clock?

Most mechanical pieces use a dedicated winding key inserted directly into winding holes on the enamel dial. Turning the key clockwise or anticlockwise tensions the internal springs. Care must be taken not to over-wind the movement, stopping as soon as resistance is felt to protect the internal gear train.

Are these clocks fully working?

Operational status varies across individual pieces, with some retaining fully serviced eight-day movements while others require professional attention. Checking individual descriptions clarifies whether a movement runs and strikes. Transporting these heavy mechanical objects often disturbs the delicate balance of the pendulum, meaning fine adjustment is frequently necessary after delivery.

How do I clean the marble and bronze?

Dusting with a dry, soft microfibre cloth prevents grime accumulation on both stone and metal surfaces. Liquid cleaners and polishes must be avoided entirely, as they damage fragile gilt and ormolu finishes. Marble benefits from occasional wiping with a damp cloth followed by immediate drying, while gilt bronze requires no moisture to retain its surface character.

How do I spot a later reproduction?

Period nineteenth-century pieces display heavy cast bronze components with hand-chiseled surface details rather than uniform machine finishing. The weight of the genuine marble and the hand-painted numbers on enamel dials offer further period indicators. Screws, pins, and movement stamps matching known nineteenth-century Parisian makers provide reliable confirmation of age against modern cast copies.
