Brief History of Bulova Watches
Bulova was founded in 1875 by Joseph Bulova, a Bohemian immigrant who opened a small jewelry store in New York City. The company quickly established itself as a pioneer in American watchmaking. In 1923, Bulova was formally incorporated. In the 1940s, the company became a trusted supplier for the U.S. military, and its watches were known for their durability and reliability. In the post-war period, Bulova released many now-classic models and continued to grow in popularity.
The majority of Bulova’s mechanical movements during the mid-20th century were made in Switzerland, especially those used in higher-grade models, automatics, and watches sold internationally. These movements were produced at Bulova’s Swiss manufacturing facilities, primarily in Bienne/Biel, and sometimes based on or modified from Swiss ébauche movements made by companies like ETA, Felsa, A. Schild, and Peseux. Movements like the 10BZAC, 11AFAC, and 10CSC were Swiss-made and often featured high jewel counts, shock protection, and refined finishing.
