Collecting Bulova Accutron watches
Friday, April 17, 2009
Buying and collecting Bulova Accutron watches - the world's first tuning fork watch. Created in the 1960's and 1970's, they are now highly prized world-wide by watch collectors.
While people think the tuning fork watch was a 20th century invention, the first prototype mechanical tuning fork clock, the "pendule รง diapason", was manufactured by Louis F. Breguet, grandson of the watchmaker Abraham-Louis Breguet. Breguet filed the patent on October 26, 1866, and March 1867. He also introduced a clock with a vibrating blade and mentioned a clock with 2 tuning forks and one with 2 vibrating blades. But the low frequency of the balance wheel made it impossible to improve on the accuracy of mechanical watches of the time, and the invention was ignored until the mid 20th century.
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. 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. The transistor "switches on" and becomes a conductor instead of a resistor. The electrical current is able to flow through the right circuit. The drive-coil becomes a magnet and gives an impulse to the permanent magnet. The movement of the permanent magnet in the driving-coil also causes an induction voltage opposing the power cell voltage. The result is a very small electric current and longer battery life. The problem ofturning the linear motion of the fork into a circular motion of the hands was solved by having the index jewel connected to the fork and pushing the ratchet wheel one tooth forward at a time. The pawl jewel is fixed to the watch frame and prevents the ratchet wheel from moving backwards. The ratchet wheel was an outstanding technical achievement - 2.4 mm in diameter, 0.04 mm thick with 300 teeth, each 1/100 mm high. In one year it revolves 38 million times. To protect this delicate ratchet system, the Accutron may be set only by turning the hands forward and to avoid damaging the delicate "fingers" that push it. Another technical achievement was the coil. The driving coil has 8,000 turns made of wire with a diameter of 0.015 mm and is an incredible 90 meters long.
However while Hetzel and Bulova were banking on the Accutron being the future of the watch, the majority of the watch industry was looking in a different direction - Quartz Technology. As the quartz movement gained popularity, it became cheaper to produce and equally as accurate as the Accutron. Accutron sales began to diminish. Soon, high end electronic watches like the Accutron virtually disappeared from the watch market - replaced with low end movements from Asia, mass produced for a fraction of what it cost to create an Accutron.
It wasn't long before collectors of early electronic horology began to seek out tuning fork watches. Their limited years of production and styles made them the ideal collectable. As demand for "hummers" went up, so did the prices.
The original Accutron was the 214. They are easy to distinguish because of the unique "backset" system. This means that the crown that sets the watch is on the back, not on the side like traditional watches. The 214 came in many models - from men's dress watches to railroad models. There are even a few 214 ladies' pendant watches and some of the earlier models featured asymmetrical designs that combined stainless steel with 14 k gold. However by far the most collectable 214's are the Spaceview and the Astronaut.
Should you add an Accutron to your watch and clock collection? Why not? Many people still routinely wear the Accutrons they bought back in the 60's and 70's and many others have joined them in proudly wearing these "hummers". They are very reliable, workhorse type watches and still maintain their reputation for accuracy and style. However, it should be noted that in the 1980's, Bulova began to run out of spare parts for Accutrons, and by the 90's, they stopped taking them in for repairs all together. Parts such as original coils and crystals are a commodity today. Coil problems are the most common cause of Accutron failure, and a coil repair job can be expensive.

Where You Can Find Movado Womens Watches
Monday, April 6, 2009
Movado womens watches are often welcome as gifts – but in some cases, have real symbolism. For example, in Spain, just like many other Western countries, it is traditional for men to present women with engagement rings when their proposals are accepted. However, Spanish women often return the gesture by presenting their future husbands with designer watches. This is only one of the more unique ways in which mens watches are presented as gifts.A Short HistoryDesigner watches and luxury watches have actually been around for about 500 years, although they were usually signs of status or a tool of one's trade, as was the case for railroad mens' pocket watches and dive watches. The first men's watches appeared around the time of Martin Luther in the mid-16th Century; they were essentially miniature versions of the spring-wound wall clocks that had been invented less than a century earlier. Rather large and unwieldy, these early men's watches were worn around the neck, fastened by a chain."Bracelet watches," which were the first true wristwatches, were not mens watches at all; first appearing shortly after the American Civil War, they were actually intended to be worn by women. Men used pocket watches exclusively. It wasn't until the invention of the airplane that it became necessary to develop a time piece that allowed pilots to tell time without removing their hands from the stick.Louis Cartier, who later became well known for the production of luxury watches, was actually the first to come up with a practical mens watches designed to be worn on the wrist for the benefit of those early aviators.Citizen watches are yet another famous name in luxury watches. These were first manufactured in 1918 by a Japanese company, Shoshoka Watch Institute, which changed its name in 1930. To this day, Citizen watches are considered some of the finest and most accurate timepieces in the world.However, the standard by which true luxury watches are measured is Movado. Watches by this famous Swiss company have been famous since the first one came out in 1912. Movado diamond watches and Movado gold watches are known not only for exceptional quality, but for sleek, minimalist design. Women's movado womens watches come in almost 100 different designs. Movado mens watches also come in many different designs – so if you are planning on presenting one as a gift, it may take you some time to decide on which one to buy!

How to Find Good Movado Womens Watches
You're familiar with the custom in which a man gives a woman a ring as an engagement gift, but did you know that in some places, women give mens watches for the same reason? It's true – in Spain when couples get engaged and announce wedding plans, women will purchase designer watches for their fiancés. Right now, you're about to learn more about mens watches – and womens as well.Back in the Day…Designer watches and luxury watches are fairly new innovations, as well as specialty timepieces such as dive watches. The concept goes back quite a ways in history, however.The first mechanical clocks came into existence in Europe around 1300, during the time of such luminaries as William ("Braveheart") Wallace, Marco Polo, Jacques DeMolay and Dante Alighieri. (Interestingly, eyeglasses were invented about the same time.) These early clocks were driven by weights; spring-driven clock – from which mens watches were ultimately developed – did not come along until well over one hundred years later.The first mens watches, invented around the time of King Henry VIII, were miniature versions of wall clocks, carried on a chain around the neck. Early models were still large and none-too-dependable; nonetheless, the pocket watch ultimately became a standard accessory for gentlemen starting in the 1600s and lasting until well into the 20th century (and was a required tool for railroad men).The first wristwatches were actually made for women; the "bracelet watch" was first made available in 1868. It was the advent of aviation that led to the development of the first mens watches starting with the Santos watch of 1904 (named for the famous French-Brazilian aviator).Designer Watches Since ThenThe manufacturer of that early wristwatch was Louis Cartier – a name that has since been synonymous with luxury watches. However, his is hardly the only one.Abruptly yanked into the Industrial Age from a medieval society that had been unchanged for over 1,700 years, the Japanese wasted little time in catching up to the Western World. Citizen watches, still a hallmark of timepiece quality, were first made in 1918 by the Shoshoka Watch Institute, which became Citizen in 1930.Another famous name – from a country the name of which is practically a synonym for fine watchmaking – is that of Swiss company Movado (Esperanto for "always in motion"). Movado watches have been famous since before the First World War. Movado diamond watches and Movado gold watches combine elegant, minimalist style with state-of-the-art, cutting edge technology for some of the most accurate timepieces on Earth. If you are considering one of the many women's Movado watches, you may have a difficult time; there are nearly 100 different Movado women's watches to choose from – and nearly as many models of mens watches!
