Great looking 1972 wind-up Helbros watch with date and sub-second dial. Chrome finish is good on the front and sides but it's pitted on the back. See my other listings for some more interesting watches including Longines and Omega.

There is a lot of literature on the Internet describing the history and development of the Bulova Accutron, so I’m not going to repeat it on this site.

But as a very brief introduction, the Accutron is like no other battery driven watch, or mechanical for that matter: it is driven by a tuning fork vibrating at 360-480 times a second, depending on the model; as a result, it doesn’t tick, but hummms.

The Longines name and names of various Longines watch models are trademarks of Longines and the Swatch Group, and are shown herein for educational purposes only.

Watches were produced using the "etablissage" method, where individual tradesman working out of small studios or their homes would produce parts (or sub-assemblies) which were then assembled and sold under the auspices of a single brand.

In 1832, Auguste Agassiz began selling etablissage-produced watches under the name "Agassiz & Compagnie" and was particularly successful selling those watches in North America.

In the end, when quartz watches started to appear in the early 1970’s, Bulova initially continued to cling onto their tuning fork technology and combined it with quartz control to produce the Accuquartz. Bulova used a simple letter-number code system: ‘M’ means 1960s, while ‘N’ means 1970s.

In the early 1800's Swiss watchmaking was truly a cottage-industry.

Although most didn’t have those wonderful Richard Arbib designed cases like the Hamilton Electrics, the Accutrons had many other things going for them: they were reliable and extremely accurate, you could see the tuning forks on some of them (the Spaceviews), but most of all, they didn’t tick, they hummmed!
