Now it is difficult to imagine - that time,when, in order to answer the elementary question by modern standards: "What time is it now?" - people had to resort to the most complex, and truly magical actions with devices that determine the time with the help of the sun, water or fire. Today every person on his hand has a simple device - wristwatches, with their help we can always easily determine how much time is now and always will pass in time for the scheduled meeting.
Wristwatches are not only a true and indispensable device, but an elegant accessory on your wrist is an attribute of a successful person.
Externally, the watch has a completely diverse appearance. Now produce a huge number of serial watches, economy class, foreign production, their famous copies ( ), watches of elite category. Fancy and elegant watches will not leave indifferent even exquisite users.
Despite the external variety, the clock's internal clockwork is based on two main platforms: mechanical, quartz (electronic).
Mechanical watches:The clock is based on the action of a compressed spring. The source of power of this mechanism is a tightly wound spring. After the establishment, the spring begins gently to unwind and sets in motion the pendulum, which activates the entire clockwork; the mechanism starts to rotate the arrows at predetermined intervals. In a mechanical clock, the dynamics of time are monitored with the help of arrows.
The mechanical watch must be periodically started, since the spring is fully unwound. All (Swiss) is based precisely on this type of watch movement.
Due to the fact that the spring is untwisted (inoperation) is uneven, there is a relative error. Despite the fact that the clock on the mechanical platform is sensitive to weather conditions (humidity and dust concentration in the air), they need to be started daily and there is a certain temporary error, this watch continues to be the leader in the world market of the watch industry.
The second type of mechanism is the quartz(electronic). The source of power of the clock mechanism is a salt or solar battery. In such a clock, a mechanical pendulum replaces a quartz crystal. Using an electronic generator with the use of a crystal of quartz, a stable, periodic pulse is transmitted to the clockwork mechanism of the watch. The main difference from mechanical watches is the possibility of placing on the watch dial not only an arrow mechanism, but also a digital display.
Кварцевые часы более точны, но нет ничего вечного.The crystal of quartz is characterized by "aging", the hours begin to rush. Quartz watches are less whimsical in operation, are not sensitive to natural conditions and do not require a daily plant.
What type of hours to choose is up to you, but living on time is very important. Punctuality will now go above everything in a society with mesh rhythms of life.
