History & Legacy of Bulova

The Bulova Watch Company is a distinguished American watchmaker with a legacy spanning more than 140 years. Founded in 1875 by Czech immigrant Joseph Bulova in New York City, the company quickly earned a reputation for innovation and precision in timekeeping. Originally producing high-quality pocket watches and jewelry, Bulova became a pioneer in the wristwatch market by the early 20th century. Notably, the brand introduced the first full line of men's wristwatches in 1919 and was among the first to implement standardized production across its timepieces. Throughout the decades, Bulova led numerous horological milestones, including the launch of the first television commercial in 1941. In 2008, Bulova was acquired by Citizen Watch Co. Ltd. of Japan, forming Citizen Watch America. Today, Bulova continues to offer a diverse range of watches—from classic automatics to cutting-edge precisionist models—renowned for their craftsmanship, reliability, and iconic American style.
