In 1922 Marius Lavet, who had been closely associated with Favre-Bulle, published his notes on electrical timekeeping. In the same year Hatot produced prototypes of their battery electric clock based on M. Lavet's designs, and also in that year M. Lavet became a director of Etablissement Leon Hatot et Cie. Construction continued until at least 1948
