What to watch the pendulum frequency and their meanings

Watch also called the wobble frequency watch, watch movement actually refers to the balance wheel in the number of vibrations per unit time, physical objects on the vibration frequency is in hertz, but the watch (watch) Few have this habit, usually half-oscillation to count, that is to swing around once each count; Hertz (Hz) units are the means to do all the shock, both objects in the unit time to complete the full number of shocks, unit of time is in seconds, watch the traverse is the practice of using time / unit of time to do that within an hour or so swing balance (vibration) the number of times, usually with A / H or V / H unit to do.

    Balance wheel in watches is to do high-speed swing, but if it converted into a Hertz unit, this value will be relatively small, usually in the 2.5 ~ 4 Hz between the mechanical and electronic shock will never usually have a limit, not is unlimited increase, the geometry of the object and the shock of a relationship, all things small and thin the frequency of oscillation can be higher, so high-frequency watch balance wheel diameter is relatively small.

    Clocks and watches in the development of the history of the formation of many forms of swing frequency, such as: a small alarm clock is a 12000A / H or 14400A / H, and the early watch (watch) are 18000A / H, about 40 years ago, watches wobble began to be raised because it is recognized that the high frequency balance wheel, and various forms of resistance to outside interference, change, the impact of ability, so travel time stability, accuracy can be improved.

    Incidentally, 19800A / H, 21600A / H, 25200A / H, 28800A / H, 36000A / H, 43200A / H, 72000A / H, and so the frequency of high-frequency or UHF type of watch, it should be said over 36000A / H Even the ultra high frequency, and typical as Longines and Zenith are more adept at doing this kind of high-frequency watch.

    Relatively fixed standard of frequency is 21600A / H, 28800A / H, because all high-frequency watch, balance wheel escapement and the dimensions of the components to be smaller, more detailed gear, wheels spin and release quickly for materials, machine processing, tolerances, lubrication of the unusually high demands to know where the high-frequency vibration or movement of things, are certainly short-lived.

    28800A / H put frequency of the watch should be a more comprehensive selection, with some specialized high-precision mechanical chronograph, the pendulum will be ultra-high frequency, it can not even own automatic start-up, balance work, they do not see a significant swing, only difficult to see the slight tremble. Watch balance wheel and spring are the most important components, they are a habitual component, the other is the elastic component, together make up the mechanical oscillator, do not stabilize the shock attenuation, but also with the escapement and to achieve. High-frequency watch escapement escapement wheel in the number of teeth, at least 20 more (and low frequency of only 15 teeth), size is also small, high precision machining.

    Although a small number of 4 Hz, in one second, put all four rounds have been completed around the swing, and not won, all in an instant. Past a small mechanical alarm clock, you can hear it when walking the beat, ticking, ticking ... and the beat now watch a short travel time almost did not get the kind of intermittent, sweep second hand running like a dial scale that also like. Ticking only belong to the past, modern high-tech society, the success or failure more often between only a moment.

    Decided to go watch when the wobble is not a major factor in accuracy, but the anti-interference ability that is certain, if you often go out and do intense exercise regularly, wear this watch is still good.

    Watch for the wobble of the unit conversion: put frequency value is divided by a 7200 Hz units can be converted, for example: put frequency of 28800A / H, and its vibration frequency of 4 Hz.
