This book describes the variety of movements found in the clocks that were produced by the thousand in France. The details of the simple timepiece, strikers, alarms, quarter repeaters and grande sonnerie are shown and discussed here. Over 220 detailed and accurate drawings display the operation of the more complex parts and the text describes symptoms, faults and corrections of each type of movement in turn, with other chapters on tools, major repair techniques, cleaning, maintenance and a list of suppliers of materials. Also included are eighteen colour photographs showing a selection of clocks and their movements.
