How to Care for an Antique Mechanical Clock
An antique clock combines a precision movement with a case, dial, hands, weights or springs, and often decorative materials. Care requires coordination between a qualified clockmaker and, where necessary, a conservator.
Assess before running
Do not wind or start a clock that has been stored, transported, damaged or left unserviced for years. Old oil can harden and abrasive dirt can accelerate wear. Ask a clockmaker for a mechanical assessment.
The [Canadian Conservation Institute](https://www.canada.ca/en/conservation-institute/services/care-objects/industrial-collections/basic-care-clocks-watches.html) recommends a full assessment before repair intended to return an old clock to operation.
Position securely
Use a stable, level surface or suitable wall fixing. Keep the clock away from direct sun, radiators, fires, damp walls and strong vibration. Longcase clocks require correct levelling and case stability.
Move it correctly
Before transport, follow specialist instructions to remove pendulum, weights, winding key and other loose parts. Label and pad each component. Never carry the complete clock by a handle, finial, hood or dial surround.
Keep the movement clean
Do not spray lubricant, penetrating oil or household cleaner into a movement. Too much oil attracts dust and can migrate onto dials and cases. Lubrication points and products vary; servicing should be performed by a competent clock repairer.
Protect the dial and case
Do not touch painted, enamelled or silvered dials. Dust a stable wooden case according to its finish, keeping wax and polish away from the mechanism, metal mounts and dial.
Operate gently
Use the correct key and follow the maker or specialist's winding instructions. Never force resistance or turn hands backwards unless a knowledgeable clockmaker confirms the movement allows it.
Keep service records
Record dates, work, replaced parts and the repairer's details. Retain original parts even if replacements are needed, and ask that irreversible changes be explained in advance.
Stop the clock and seek help for grinding, sudden stopping, loose hands, damaged cords, unstable weights or a case that moves during operation.
