Mark and John Coxhead have been restoring French carriage clocks since 1994.
The two most frequent reasons for an antique carriage clock needing repair are that it has either stopped working altogether, or that it has become unreliable at keeping accurate time.
Many carriage clocks have been running twenty four hours a day, seven days a week, for many or possibly hundreds of years.
It is therefore not unusual for some of the clock parts to have become worn, and for them to be in need of either a service, or a repair or both.
