What is an Accutron?
ACCUTRON stands for “ACCUracy through ElecTRONic”. The world’s first electronic watch functions with a tuning fork; a small fork-shaped piece that until then had only been used in music. Engineer Max Hetzel developed its transistor movement, which was able to achieve an unprecedented precision of a minute per month.
How does an Accutron work?
The “Bulova Accutron” has a frequency of 360 oscillations per second (360 Hz). The vibration of the tuning fork is controlled by a transistorized circuit in the following way: when the left magnet on the tuning fork moves to the right, the phase-sensing coil generates an induction voltage on the base of the transistor.
How do you phase an Accutron?
Phasing an Accutron is adjusting the index mechanism so that the index jewel is resting exactly one-half of the distance along one tooth, and the pawl jewel is butting hard against the face of another tooth, when the tuning fork is at rest.
Are Accutron watches battery powered?
The Accutron watch was developed as a solution to the battery powered watches that came on the market in 1952. The battery powered watches were not very accurate and Bulova saw a need for accuracy in certain circumstances, like the military.
Are Accutron watches still made?
Today, the tuning-fork movement is no longer produced, and Bulova has mostly stopped using the Accutron name. The brand, however, did produce a limited collection of watches (using a Precisionist movement) called the Accutron II Alpha in 2014 that recalled the open dials of early Spaceview watches.
How accurate is an Accutron watch?
The Accutron’s movement was claimed to be accurate to around one minute per month, or two seconds per day — leaving mechanical movements in the dust. It operated at 360Hz, resulting in the aforementioned humming sound and a seconds hand that sweeps like that of a mechanical watch, only more smoothly.

What is an Accutron watch and how does it work?
The Accutron was certified as the first watch for American railroads; it was used by rail workers to synchronize trains. Bulova’s Accutron watches soon became a hit with the Accutron Astronaut being its second model. This watch was developed for NASA’s spatial program and followed up by the Astronaut Mark II model.
Is the Bulova Accutron gold the most collectible Accu-tron?
So it hid the crown at the back right beside the battery port. The original models had a 14k yellow gold case, but the later models were fashioned out of stainless steel and a gold-filled bezel instead. Thus the Bulova Accutron gold is without a doubt a highly sought after collectible Accutron.

What is bulbulova Accutron?
Bulova’s promised accuracy was down to a new type of watch movement, called the tuning fork, designed by electronics engineer Max Hetzel. What’s more, rather than ticking like regular mechanical watches of the time, the Accutron hummed.
