Swiss engineer Max Hetzel developed the tuning fork concept after joining Bulova in He created a working model in , moving it to prototype stage in It was developed in secret, even as electric watches gained acclaim. It was an important step in the development of electronic and quartz watches. Where quartz movements excite a vibration in quartz crystal for timing, the Accutron instead used electromagnets acting on a tuning fork.
This tuned vibrating member oscillates at oscillations per second Hz , much faster than the balance wheel found in a mechanical watch 2. This was far better than competing mechanical watches, causing a sales and publicity surge.

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. The watch had the caliber movement, which was used in the first years of production. Pieter Doensen, a Dutch watchcollector, has written a book called “Watch” which has dedicated some chapters to tuning fork watches. The most well known models of the Bulova Accutron watches are probably the Astronaut and the Spaceview.
The Astronaut is the least confusing model, since there was only one model available in several flavors ofcourse , as shown below. The model above was very populair, especially amongst US pilots during the Vietnam war.

While Bulova had grand plans for their watch of the future, they never anticipated the success that the uniquely appointed Spaceview would generate. Designed to be a salesman’s tool and display watch only, the Spaceview was never intended for retail purchase. But when demands for the watch spiked, Bulova responded, producing retail versions of the watch with the same unique characteristics of their display models.
While in production for about 17 years all together, the tuning fork technology was eventually beaten out by quartz crystal movements, making this unbelievable piece of history a short-lived, but totally revolutionary wristwatch. So no matter your mechanical-movement inclinations, there is no denying that the Spaceview is a one-of-a-kind piece of horological history.
Oh, and the humming?
