Electric clock Halmilton 1957, Halmilton Watch Co. of Lancester, Pennsylvania, produced the world's first electric clock. Hours electrically Hamilton set a time with traditional -mekanisme balance wheel has been used in parts hours for hundreds of years and hence no more accurate than another hour. However, rather than provide the mechanical strength of the spring, a battery is used to give power to the mechanics that requirement is no longer necessary rounds. Although people love the fact that they no longer use round the clock, it stops when the electrical contacts become corroded where there was not before long the life span of an hour. It makes a headache for Hamilton repair department which is continuously updated on the deal until 1961. Accutron by BulovaPada around that time, Bulove provide the next major enhancement in the timing of electrically with their Accutron watch in 1960. It comes in the form of chunks forms U of nickel alloy that vibrates in response to electrical current from the battery.
The vibration frequency is higher than the traditional rodagaya, so for the first time an electric intercession be a neat idea which gives power to the clock by offering better accuracy anyway. Accutron is also working on the electrical contact issue further by introducing transistors, providing long hours of working time without having to wear it. This clock is also closely associated with the US space program that is used on aircraft angakasa Mercury and Apollo were used by NASA to go to the moon. Smooth the movement JamInovasi SwissBagaimanapun, Bulova frightening success of the Swiss watchmaker, who saw the potential challenges to their dominance in terms of the quality of the timer. Bereka united to fund research lab CEH (Center Electonique Horloger). CEH targeting their research to find oslilator more accurate than sepatukuda nickel. Quartz movement has been used for the first time in hours in the 1930s; until the early 60s they even have used it in naval chronometer (although there is no denying the accuracy can not be predicted). CEH set about increasing the accuracy and up to the mid 60s and Bernard Golary Longines has created a pocket watch that has an accuracy up to 0:01 seconds a day. In 1967, CEH produce watches with quartz movements first.
In regard to the increase in microelectronics, the integration of electronic circuits has increased which makes it more energy efficient, thus making it able diminaturisasi quartz movement can fit in a wristwatch. However, the Swiss manufacturers continue to refine their mechanical engineering and then equaled Bolova through traditional means. After years damapenelitian, Switzerland saw quartz as a fad that will pass, taking into account the mechanical advantage of their error which will show them to survive as king of the heap; it is poor judgment which will sometimes lead to death in some companies.
While the Japanese interpretation of the Europeans play one-upmanship with their various techniques, Seiko has continually take a fresh look at quartz and it is a Japanese company that issued the first quartz watches in the world - Clock Astron 25SQ - in Japan on December 25, 1969 . Valuable expensive, with a price of 450,000 yen ($ 1,250 in 1969 exchange rates). Having a flat face, clumping (unlike the Swiss mechanical watch is thin) and also painful with so many technical difficulties that made Seiko end by pulling it after producing only 100 hours. However, despite the apparent failure, it also marks a new stage in the technology of hours where we will never turn. Quartz technology has been at a new step forward in the year 1970; many Japanese watchmaker Seiko follow the path, also made the Americans, until sometimes when Switzerland climb to join - though not until some other manufacturer collapsed. This competition leads to thinness, the hours are more hungry accuracy. Even with the addition of more features such as the progress of the 70s, the next leap was just going nowhere.
