Thanks to his commitment and to his skills, the profits grew quickly and Joseph, noting the growing demand for watches, decides to expand his business with the production of watches.
In 1912 he opens in "Bienne", in Switzerland, a factory for the complete production of parts of watches, organizing the production in a brilliant and revolutionary way and creating an assembly line.
All the models of watches for houses, table clocks, as well as pocket and watches, brought on the dial the inscription “Bulova”.
In 1919 Bulova produced his first full collection of wristwatches for men and jewel watches for women whose launch was supported by an extensive advertising campaign in the USA.

After World War II in the "Bulova watchmaking school" located in Woodside in Queens, he offers free to veterans a rehabilitation associated with a specific training to work.
In 1950 Bulova opened the way to the electronic watches with the futuristic "Accutron", ruled by a fork with vibration at 360 Hz. that allowed Bulova to guarantee wristwatches with a maximum variation of a minute a month.
Before technology "Accutron" was commercialized, NASA used it in the space project of "Satellite Vanguard 1".
The "BULOVA Accutron" model with the "squelette" aspect that allows the view of the tuning fork, electronic circuits and mechanical parts, becomes a "Status Symbol" and is launched with the slogan "The clock of the Space Age".
In 1967, the Bulova brand became synonymous of technological vanguard and precision and is adopted from '"Air Force One" of the US President; then, for its high precision, it was adopted by all the US railwaymen.
Always in 1967 Bulova acquires a Swiss factory named "Universal Genève" that was ceded again in 1977 as a result of difficult financial situations faced by manufacturing.
Since 1984, the Bulova has only operated as a commercial enterprise.
