The book "La Comtoise - La Morbier - La Morez: Histoire - Technique" by Francis Maitzner and Jean Moreau is indeed one of the standard works on the Comtoise clock.
The work offers a comprehensive historical account of the Comtoise clock from the 17th century to the 20th century. It describes the stylistic development with a clear chronological classification and contains numerous photographic illustrations as well as detailed photographs of cases, dials, movements and pendulums. Technical aspects of construction, mechanics and decorative design are also explained. In addition, there are references to regional variants from Morbier and Morez.
