Bulova is a subsidiary of the Japanese group Citizen Holdings, which is known among other things for its tuning fork watch Accutron and manufactures watches in the USA and Switzerland.
Joseph Bulova (1852 to 1935), an immigrant from Bohemia, set up his own business as a watchmaker in New York in 1875, importing movements from Switzerland and fitting them into cases he made himself. These activities resulted in the founding of his own factory in Biel, which Joseph's son Arde subsequently managed and considerably expanded. Increasingly, the company produced wristwatches. Bulova strove very hard for a low rate deviation, giving important impulses to the development of automatic wristwatches.
