  • Finding a Mechanical Watch
    publié le 11/10/2021 à 08:50

    There are some things that make finding a mechanical watch almost impossible, even when one knows how to look. To put it simply, in order to find one, you have to be very well versed in the field of watches and their mechanisms. Put simply, in order to find a mechanical watch, it is like finding a mechanical watch on the ocean floor and then trying to figure out in details how it functions. At the same time, finding a mechanical watch on the ocean floor is like finding a mechanical watch on Mars and trying to figure out how it works from orbit.

    Mechanical watches generally have two parts - the case and the dial. Typically, the case of a watch is made of hardened rubber called the caseback. On the other hand, most quartz watches use crystals to create the liquid crystal oscillator inside them. Inside these crystals are tiny magnetic circuits that link the crystal oscillator with the rest of the watch. Without these small circuits, there would be no way for the crystal to create the electricity necessary to power the small electrical motors which turn the hands, etc.

    When the two parts of a quartz crystal oscillator circuit are in motion, they cause a small electric field that links up their two parts, creating the electricity needed to power the device. In order to understand why this happens, we must know a little bit about the mechanics of the quartz crystal oscillators themselves. These crystals excite a strong electric field which results in the generation of a large quantity of electricity. This electricity passes through a large number of miniature conductors that all bend the wave as it passes through the crystal oscillator circuit.

    In order to fully understand how this works, we must first understand what happens in a typical mechanical watch. The mechanical design of most watches utilizes a series of hollow tubes called the case or the bracelet. Inside these tubes are miniature crystals which are controlled by an electric current passing through them. As the current passes through the case or bracelet, these crystals resonate and produce an electrical field which links up the individual crystals and produces the electrical current that forms the electrical signal which causes the movement of the timepiece. The resonant frequencies produced by the quartz crystals which make up the case or bracelet, and the different resonant frequencies produced by the individual crystals in the crystal oscillator circuit, form a mathematical solution known as the resonant frequency.

    The question now becomes "how do these different frequencies generate an electrical signal?" The answer is simple: the mechanical design uses a series of conduction cups which push the quartz crystals inside the quartz watch back and forth. Since each crystal has an associated resonant frequency, the frequencies cancel each other out as they travel through the case, causing the generation of a unique electric signal. Of course it must be kept in mind that not all mechanical watches use the same construction method. What one mechanical watch relies on for its efficient design is the use of one particular type of crystal oscillator. Regardless, many manufacturers have taken the idea of using these crystals in a quartz watch and adapted it for use in their own line of watches.

    There are two properties found in most quartz crystal crystals which provide the mechanical pressure required by a quartz watch. These properties are the inherent high frequency which is directly related to the distance the crystal vibrates and the dielectric property which directly relates to the change in the voltage across the crystal. These two properties are the main reasons why watches use the mechanical pressure which results from the motion of the pendulum. If the distance traveled by the pendulum is greater than the value of the natural frequency of the quartz crystal, there is a positive charge produced. If the pendulum's frequency is less than the natural frequency, then there is a negative charge produced.
