Today, wristwatches are a must-have for many people. True, the functional component of the watch is now inferior to design, style and prestige. And, for sure, almost any person, when choosing a watch, was faced with the question of which mechanism to choose for themselves.
Instructions
Step 1
As you know, all watches are divided into two groups: quartz and mechanical. They have their own merits and demerits. Their main difference lies in how the mechanism itself works. It is known that in a quartz watch, a conventional battery is used as an energy source, which supports the power supply of the electronic unit and the stepper motor. Once a second, such a block sends a signal to the engine, which, in turn, makes the arrows turn.
Step 2
The quartz crystal, from which the watch got its name, provides high accuracy. The accuracy of such watches is very high, their annual deviation from the exact time is on average 5 seconds. The battery on a quartz watch is designed for several years of operation, so there is no point in winding it up.
Step 3
Mechanical watches use a coil spring in a toothed drum. When wound, the spring inside is twisted, and when untwisted, it forces the drum to move, which provokes the movement of the entire watch mechanism.
Step 4
The accuracy of a mechanical watch depends on a variety of factors, such as ambient temperature, wear and tear on parts and adjustments. But in quartz watches, everything is much simpler: none of the factors affects their mechanism. The accuracy of their course is determined only by the frequency of the pulses coming from the crystal oscillator, and it is constant. The engine and arrows are just an optional extra. Their main task is to rotate on command. Therefore, mechanical devices are less accurate than even the cheapest quartz watches. But on the other hand, their cost is very different from each other due to the fact that there are many small hand-made parts in mechanical watches. It can often be 20 or 30 times the cost of a good quartz watch.
Step 5
All parts of mechanical watches are under the main part of the time under the load created by the mainspring, and only for a short period of time the tension decreases when the balance and anchor fork allow the escape wheel to turn. Such heavy loads lead to the fact that steel, brass or even ruby is used as a material for the manufacture of watches. In a quartz watch, the opposite happens: most of the time the parts are in a free state, the load occurs only when the hand moves, which makes it possible not to install such solid materials or stones into the mechanism.
