The wall clocks that you will find on our website date back from the 19 th and 20 th century. Most of them are made of wood, some brass, faience, sheet metal, bronze or sometimes an assortment of these materials. The types of movement they house are diverse, from movement de Paris, to foret noire, comtois, tic-tac, or even electric for the ATO and BULLE-CLOCK. The foret noire movement in which the springs have been replaced by weights has a power reserve of 24 hours, whereas the others have an eight days power reserve, except for the electrical movement, which runs until the battery dies. A metal spring for the ringing. Some have a ring shaped balance instead of the traditional one. The adjustment is done in the same way as non wall clocks.
