Those three date ranges are differentiated by the presence or absence of certain case and movement markings as well as the nature of any such markings, as explained below. In general, for all time periods, it is important to understand that Bulova watches never provide an obvious date of manufacture anywhere on the watch.
Rather, the date must be “de-coded” using symbols, serial numbers, and two-character codes placed on various parts of the watch. These codes and the manner in which they should be interpreted is the subject of this article. Many observers of Bulova watches are confused by the sometimes seen patent dates stamped on the inside of some Bulova watch cases, and they misinterpret such dates as the time of manufacture. In point of fact, those patent dates apply only to certain aspects of the case design and indicate only when those general designs were patented.

There seems to be a problem serving the request at this time. Bulova is an American watch brand founded in and currently owned by Japanese conglomerate Citizen Watch Co. It manufactures watches and clocks and is based in New York City. Bulova produced the world’s first television advertisement, on July 1, the first day that commercial advertising was permitted on television in the United States. The tuning fork was powered by a one-transistor electronic oscillator circuit.
Instead of the ticking sound made by mechanical watches, the Accutron had a faint, high-pitched hum which came from the vibrating tuning fork.
It is no surprise to me that the “Spaceview” watches (see below) were a great Likewise, I have seen some Accutron panel clocks with a date window; again Bulova Accutron Astronaut 18K Gold HN M1 Case D
In , Joseph Bulova, a Bohemian immigrant, started the J. Begun as a wholesale jeweler, the company produced small table clocks and good-quality pocket watches, By , driven by the increased demand for wristwatches, Bulova built a factory in Bienne, Switzerland that was capable of mass-producing fully-jeweled wristwatch movements in large numbers. For the most part, these movements were cased and timed in the USA before shipment to retailers.
Under Joseph Bulova’s guidance, Bulova became a world-leader in the mass production of reliable, good-quality wristwatches. Bulova sold relatively few pocket watches compared to their huge production of wristwatches , though they did produce a few basic pocket watch models in the 30’s, 40’s and 50’s. The ultra-thin “Phantom” model, produced in the ‘s, was a finely-made, platinum-cased pocket watch that is prized by collectors today.
Bulova was an innovative company, and can be credited with many industry “firsts. They were the first watch company to market watches specifically to women, and the first company to open a school for disabled veterans that provided them with care, employment opportunities, and a marketable skill after the war more below. One of Bulova’s most significant contributions to the world of horology was the creation of the Joseph Bulova School of Watchmaking, founded in by Joseph Bulova’s son Arde Bulova then Chairman of the Board.
Arde Bulova “wished to repay, in some small measure, the sacrifice and service of returning disabled veterans after the Second World War. The Bulova school helped train an entire generation of American watchmakers. The school provided tuition-free education to teach disabled servicemen the skills of watchmaking “under the most expert supervision and with an all-inclusive curriculum in a pleasant environment where similar interests and problems developed a close-knit, affable group of men working toward common goals.
Watch Information and History
Review : Bulova Accutron cal. In the s, the days of mechanical watches only, companies started looking at other possibilities to design and produce accurate watches. It seems that chronometer specifications weren’t accurate enough, or maybe too expensive for a lot of companies. One of these companies developed the Accutron movement, an electrical movement that used a tuning fork and that was powered by a battery.
Another companies known for their electronic watches were Junghans today known for the “radio controlled” watches and their Bundeswehr watch and Hamilton. The inventor of the tuning fork watch, Max Hetzel, developed the first tuning fork system in see here , but the components for a complete watch were not available at that time.

Like conventional watches, Bulova Accutrons have a train of gear wheels to drive the hands. However, that is basically where the similarity ends. In an Accutron, there are two areas of special interest to use. One is the Electronic Circuitry, and the other is the Index Mechanism. While it is relatively simple, it is nevertheless interesting how the electronics driving the Accutron work. The electronic circuit combined with the tuning fork forms a simple oscillator.
Each of the ends of the tuning fork has a little magnet on it. The fork provides the resonant or tuned part of the circuit.
