Bulova is (formerly) an American watch manufacturer founded and incorporated as the J. Bulova Company in 1875 by Joseph Bulova. It was reincorporated under the name Bulova Watch Company in 1923, and became part of the Loews Corporation in 1979, and subsequently sold to Citizen Watch Company of Japan at the end of 2007. 

In 1912, Joseph Bulova launched his first plant dedicated entirely to the production of watches. Manufacturing watches at their factory in Biel, Switzerland, he began a standardized mass production new to watchmaking. In 1919, Bulova offered the first complete range of watches for women, and a men’s collection in 1924. The visual style of his first popular advertising made its watches popular with the American public. But beyond the original style, precision and technological research also became imperative for Bulova. In 1927, he set up an observatory on the roof of a skyscraper located at 580 5th Avenue to precisely determine universal time.

Bulova established its operations in New York, where it made innovations in watchmaking, and developed a number of watchmaking tools.^[4] Its horological innovations included the Accutron watch, which used a resonating tuning fork as a means of regulating the time-keeping function. Their tuning fork movement went unto be licensed and used by other companies, including Omega.

Bulova produced the first advertisement broadcast on radio in 1926, announcing the first beep of history: ‘At the tone, it’s eight o’clock, Bulova Watch Time’, an announcement heard by millions of Americans. In 1927, Charles A. 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 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.

Bulova produced the world's first television advertisement, on July 1, 1941 (the first day that commercial advertising was permitted on television), before a baseball game on New York station WNBT. The announcement displayed a WNBT test card modified to look like a clock with the hands showing the time. The Bulova logo, with the phrase "Bulova Time", was shown in the lower right-hand quadrant of the test pattern while the second hand swept around the dial for one minute. 

In 1945, Arde Bulova, Chairman of the Board, founded the Joseph Bulova School of Watchmaking to provide training for disabled veterans after the Second World War. The school later became a full-fledged rehabilitation facility, an advocate for disabled people nationwide, and one of the founders of wheelchair sports in the United States. The school closed in 1993.

In 1967, Bulova bought the Manufacture des Montres Universal Perret Frères SA at Geneva and sold it in December 1977. The factory in Biel was closed in 1983.

Bulova’s "Accutron" watches, first sold in October 1960, use a 360 Hz tuning fork instead of a balance wheel as the timekeeping element.^[11] The inventor, Max Hetzel, was born in Basel, Switzerland, and joined the Bulova Watch Company in 1948.^[11] The tuning fork was powered by a one-transistor electronic oscillator circuit, so the Accutron qualifies as the second "electronic watch", following the Hamilton Electric released in 1957. Instead of the ticking sound made by mechanical watches, the Accutron had a faint, high-pitched hum which came from the vibrating tuning fork. A forerunner of modern quartz watches which also keep time with a vibrating resonator, the Accutron was guaranteed to be accurate to one minute per month, or two seconds per day, considerably better than mechanical watches of the time. 

In the 1960s, the company was involved in a rivalry with Omega Watches to be selected as the 'first watch on the Moon'. In 1971, a Bulova chronograph was carried on board Apollo 15—the fourth mission to land men on the Moon—by mission commander David Scott. All twelve men who walked on the Moon wore standard Omega Speedmaster watches that had been officially issued by NASA. Those watches are deemed to be government property. 

Transcripts from the Apollo 15 Lunar Surface Journal attest to the fact that during Scott's second excursion on the Moon's surface, the crystal on his Omega watch had popped off.^[13] So, during his third lunar walk, he used his backup Bulova watch. The Bulova Chronograph Model #88510/01 that Scott wore on the lunar surface sold for $1.625 million, making it the most expensive astronaut-owned artifact ever sold at auction. The company released an homage edition of the lunar watch in early 2016, using a modern high frequency quartz movement for the watch that took more than 40 years to make its way into production line.

Currently Bulova designs, manufactures, and markets several different brands, including: the signature "Bulova", "Caravelle" (formerly "Caravelle New York"), the formal Swiss-made "Wittnauer", and the "Marine Star". In 2014 Bulova ceased the sale of watches under the "Accutron" and "Accutron by Bulova" brand.

In 2010, Bulova introduced the Precisionist, a new type of quartz watch with a higher frequency crystal (262144 Hz, eight times the industry standard 32768 Hz) which is claimed to be accurate to ±10 seconds per year and has a smooth sweeping seconds hand.
