How do I wind a mechanical mantle clock?

Insert the matching winding key into the dial arbor and turn it gently clockwise until firm resistance indicates the mainspring is fully tensioned. Avoid over-winding to protect the internal brass teeth. Ensure you support the clock case with one hand while operating the key to prevent accidental slips against the wood, marble, or glass panels.

How do I tell an antique carriage clock from a desk clock?

Carriage clocks traditionally feature heavy brass and glass frames with integrated carrying handles on top, designed originally for officers travelling in the nineteenth century. Desk clocks often utilise streamlined materials like chrome, bakelite, or marble without the characteristic folding handle. Examine the movement through the side glass panels to identify platform escapements typical of portable carriage designs compared to standard domestic house movements.

Why does my clock lose time?

Variations in temperature, minor shifts in surface level, or a buildup of dried oil within the brass gear train can alter the oscillation rate. Regulating the movement via the adjustment index on the balance wheel or pendulum often corrects the timing. Older mechanical movements require periodic cleaning and fresh lubrication by a horological specialist to maintain consistent operation across their eight-day cycles.
