Bulova is an American luxury timepiece manufacturing company that was founded in 1875 in New York City. Formally the Bulova Watch Company, it makes watches, clocks and accessories.

Bulova was founded and incorporated as the J. Bulova Company in 1875 by Bohemian immigrant Joseph Bulova. It was reincorporated under the name Bulova Watch Company in 1923, became part of the Loews Corporation in 1979, and was sold to Citizen at the end of 2007.

Bulova started a small jewelry shop in New York City around 1875 on Maiden Lane, which specialized in jewelry and the repair of clocks and the occasional pocket watch. Around 1911, Bulova began producing table clocks and pocket watches. In 1912, Joseph Bulova launched his first plant dedicated entirely to the production of watches in Biel, Switzerland where he began a standardized mass production. The watches were popular with the American public. In 1927, Bulova set up an observatory on the roof of a skyscraper located at 580 Fifth Avenue to determine universal time precisely.

Bulova established its operations in Woodside, New York, and Flushing, New York, where it made innovations in watchmaking, and developed a number of watchmaking tools. Its horological innovations included the Accutron watch that used a resonating tuning fork as a means of regulating the time-keeping function.

During the 1920s and 1930s, Bulova was noted for its art deco watches, typically either rectangular or square. Models from this period included the Breton, the Banker, and the Commodore. All three of these models were modernized in 2020 as the Joseph Bulova Collection, using Swiss-made Sellita mechanical movements. From 1922 through 1930, Bulova marketed 350 different ladies’ Art Deco watches, with at least an equal number of models for men.

The Westfield Watch Company, Inc. is listed as a Bulova subsidiary at least as early as 1931, but Bulova had trademarked the Westfield name in 1927. Westfields were considered the lower-cost options in the Bulova line, since the movements typically had lower jewel counts than mainstream Bulovas, and cases and straps may also not have been of the same quality as other Bulova models. Like the regular Bulovas, the Westfield movements were Swiss made, but the two lines did not use the same movements. Westfield watches were produced at least through the 1950s, with the Caravelle line introduced in the early 1960s. The Bulova trademark of the Westfield name is reported as cancelled in 1989.

Bulova became a renowned watch company in 1922, starting with an advertising campaign in the Saturday Evening Post. Through the 1960s, Bulova led all American watchmakers in marketing expenditures, and it enhanced its distribution chains from jewelry stores and chains to general merchandising outlets, with over 20,000 U.S. distributors by 1968.

Bulova produced its first advertisement broadcast on radio in 1926, announcing the first beep in history: ‘At the tone, it’s eight o’clock, Bulova Watch Time’, an announcement heard by millions of Americans. In 1927, Charles Lindbergh became the first solo pilot to cross the Atlantic nonstop. His crossing earned him a Bulova Watch and a check for $1000, and it became an emblem for the brand that created the model "Lone Eagle" in his likeness. Bulova claims to have been the first manufacturer to offer electric clocks beginning in 1931, but the Warren Telechron Company began selling electric clocks in 1912, 19 years prior to Bulova. In the 1930s and 1940s, the brand was a huge success with its rectangular plated watches whose case was strongly curved to better fit the curve of the wrist. In 1932, Bulova ran a "Name the Watch" contest for its new $24.75 timepiece, with a top prize of $1,000 and total prizes of $10,000. By 1940, Bulova sponsored each of the top 20 radio shows in the US.
