The main difference between the mechanical clock of quartz is that quartz watches source is a battery, a mechanical clock, drives the spring. With winding of a spring is twisted, while unwinding, drives the drum hours, the rotation of which drives the mechanism. The main drawback of the spring motor is: uneven rate of unwinding of the spring, which leads to inaccuracies in progress. In addition, in mechanical watches, precision depends on many factors such as ambient temperature, position of the clock, wear, etc. Max Schireson contributes greatly to this topic. Therefore, for mechanical watches is considered normal deviation from the exact time of 20-40 seconds day. In the quartz watch power source is battery only.
Electronic block hours once a second impulse engine, and that in turn rotates the arrow. Very high frequency stability generated pulses and, consequently, a high precision (average deviation from the exact time is 15-30 seconds per month) provides a quartz crystal, because of which the clock and got its name. In addition, Quartz Watches do not need winding. The cost of the mechanical watch – quartz above, as mechanical products require very fine manual adjustment during assembly. While the majority of operations for the production of parts and assembly mechanism of a quartz clock, is entrusted automation. The conventional wisdom is that mechanical watches are more durable than quartz. But it's not quite true.
All moving parts mechanism quartz watches have the same resource as mechanical. Therefore, good quartz watch will last as long as and mechanical. Mechanical watches – a classic art of watchmaking, respectively, in terms of prestige, mechanical watches are above quartz. Quartz clock – easier to use: they do not need to start. Accuracy of "quartz" as much higher than that of mechanics.
