Carriage Clock Stop-Work

Good quality carriage clocks are often fitted with this device. It restricts the use of the mainspring so that the beginning and end of the spring, i.e. the weaker and stronger parts, are not used. It does so by limiting the number of turns that can be applied. As the device inevitably uses a little of the clock’s power, it is sometimes removed to keep a poorly maintained clock running. Like removed date and moon work, the stop-work parts are often lost necessitating the making of a new set. In this case the finger part had broken, but the owner had bought the clock in straight away, before the bits were lost, so that I was able to make a new one using the original as a pattern.
