![]() Bradley, Accutron timepieces were an instant success, the movement remained the most accurate on the market for many years. Officially introduced on 10 October 1960 by Bulova’s president, General Omar N. The tuning fork was placed between two transistors and oscillated at 360 Hz, a significantly higher frequency than that of a classic, mechanical movement. Furthermore he replaced the balance with a tuning fork, a small piece of metal consisting of two parallel arms soldered together in a U-shape and extended by a shaft. Max Hetzel believed that the inclusion of a transistor in the movement would help to increase the precision of the timepiece. With the application registered on 19 June 1953 under patent number 312290, the starting signal to produce the first prototype was given in 1954. name derived from the worlds ACCUracy and elecTRONic.Īll attempts to construct an electronic timepiece superior to mechanical timepieces in terms of accuracy had initially failed and Bulova entrusted the engineer Max Hetzel with the development of a very precise electronic timepiece. This very rare pocket watch is powered by one of the very first electronically controlled movements in the world, the Accutron.
