It is believed that this anonymous master took inspiration from the special watches made by the Bronnikov family, who were renowned for crafting wooden clocks. The family originally hailed from Vyatka, Russia. The first recorded Bronnikov was Ivan (circa 1770-1860), who was an exceptionally skilled carpenter and turner. His son, Semyon Ivanovitch (1800-1875), had seven sons, of whom Mikhail Semyonovitch and Nicolai Semyonovitch continued their father’s work. Nicolai Mikhailovitch, the son of Mikhail, was the last watchmaker in the family and left Vyatka in 1909 or 1910. It is believed that he worked for Paul Buhre’s company in Moscow.
