The famous wooden watches by the Bronnikovs are very rare and bone watches are much rarer. Far fewer examples were made and even fewer survive today. Bronnikov The Bronnikov family came from Vjatka, Russia, and specialized in the making of all-wood, and all-ivory watches. The first recorded member of the family was Ivan Bronnikov (c. 1770 - 1860), a skillful joiner and turner. His son was Semyon Ivanovitch (1800 - 1875). Semyon had seven sons, among them Mikhail Semyonovitch and Nicolai Semyonovitch, who continued his work, as did Mikhail's son Nicolai Mikhailovitch, who was the last watchmaker in the family. Nicolai Mikhailovitch left Vjatka for Moscow in 1909 or 1910 and is said to have worked there for the firm of Paul Buhre. Watches by the Bronnikovs are found in the Hermitage, the Moscow Clock Industry Research Institute, the Tbilisi Museum of People's Art, the Physics and Math Salon of Dresden, in museums in Vjatka, Slobodskoi, Veliky Ustyug, Cherepovets, and in private collections in Moscow, Angarsk, Zlatoust, and Irkutsk. Known signatures include "M.S. Bronnikov in Vjatka", "The Bronnikov Brothers in Vjatka", and "N.M. Bronnikov in Vjatka". Literature: "The Bronnikov Dynasty" by Theodore R.
