To date, the mechanism of the clock has a direct effect on the final cost of the goods. It is in a special case, so in most cases it is hidden from the eyes. This does not apply only to special watches, in which an open part of the mechanism is provided. Thus, you can observe directly the work of the product. However, when you purchase, you can estimate the quality of the clock only on the dial and the case. Depending on the type of controller used, it is possible to classify them into mechanical and quartz models.
The classic mechanism of the clock involves the twisting of the spring placed inside. This principle has not changed since the invention of the first compact products. The force is transferred to the anchor wheel by means of a spring, preventing the pendulum from stopping. The main drawback of mechanical watches is the relatively weak accuracy of the stroke. An acceptable result can be considered a lag or acceleration of about twenty seconds during the day. However, certain models of Swiss chronometers, which have protection against moisture and temperature effects, were able to show the accuracy inherent in quartz analogs. The high cost of such products and a rather complex performance is unlikely to provide an opportunity to enter mass production.
Domestic and almost all Swiss manufacturers try to use the watch mechanism with a manual way of the plant, which involves daily performing certain actions. Thus, every day a certain ritual must be made, which helps to restore the work of the steel mechanism. However, with this method it is quite realistic to reduce the thickness of the clock itself. In the modern world, an automatic plant is widely used, implying the presence of a special weight, which during the carrying out rotates the winding mechanism. The minus lies in the impressive thickness, which affects the appearance of the product.
A completely different option is the quartz movement of the watch, where the main element is a quartz oscillator that transmits a special signal with a high level of frequency stabilization. Quartz is characterized by frequency stability, which is not influenced by external factors, such as air humidity and ambient temperature. With the advent of integrated circuits, these properties were realized in hours, ensuring the accuracy of the move with an error of up to fifteen seconds per month.
Such a mechanism for the watch has simplicity, reliability and a long service life, since parts of the quartz models are devoid of constant voltage. People who prefer the Swiss mechanics, can negatively speak about such products in terms of the device. However, it is not necessary to doubt the accuracy of the move. Recently, models have appeared with a battery charge indication system, behaving in a special way when energy is depleted. Mechanisms for wall clocks have the same principles of work as manual analogs.
