The signed and numbered '' Monitor'' case opens to a dial with Roman numerals and separate sub-second hand.
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.
The Longines "Winged Hourglass" (actually a winged clepsydra for those who care about such things) is the oldest registered trademark for a watch company, having been registered in 1880. became the exclusive sales agent for Longines in 1880, starting a relationship that would last for 114 years. was sold by the Wittnauer family and renamed the Longines-Wittnauer Co., a name that became so linked in the minds of the public that most assume that Longines and Wittnauer watches are the same.
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.

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!Tags: Adult Dating, affair dating, sex dating
