Technology of wristwatches
It is an everyday object. One gives little thought to the things that one deals with every day. The wristwatch is one of these things. Every morning, millions of people put their wristwatch on their wrist without asking what technology is in the little timepieces. Whether automatic, wind-up or quartz watch, the main thing is that the watch runs correctly.
What does the quartz in my watch do?
Besides the digital watch, the most common type of watch today is the quartz watch. However, what is quartz exactly and what function does it perform in the watches? The quartz watch is the further development of the completely mechanical watch. With the quartz watch, the oscillating circuit of a piece of quartz serves the watch and not a mechanical pendulum. For the manufacture of watches, a special characteristic of the quartz crystal was put to use. As soon as a certain pressure is exerted on the crystal, this oscillates in a certain beat. The advantage is that one can control the oscillation by means of the pressure.
The energy for the quartz crystal
As a rule, watches nowadays are operated with batteries. Many have certainly asked themselves, how it is possible that these small button batteries, which are mostly smaller than a one cent piece, keep wristwatches running for years. This is primarily due to the fact that the development of the technology in the watches was already developed and is being developed. In this way, the utilization of the energy of the batteries is better and better. The quantity of energy that is not used for the function of the watch, was and is becoming increasingly smaller with the development.
The fascination of automatic watches
Even though there was already the automatic wind-up in pocket watches by 1770, the automatic watch first developed towards the middle of the 20th century into a mass-produced article. The technology behind the self-winding watch was still too complicated and complex at the time.
The progressive technology first made it possible to place the mechanics in an increasingly smaller space.
In general, an automatic watch means a mechanical watch, whose springs rewind themselves through the movements of the wearer. There is a rotor in the interior of the watch, which is fitted with ball bearings. If the watch is now moved, the rotor remains where it is due to its inertia. The housing of the watch rotates around the rotor. With this procedure, the torque of the rotor can be used to wind up the springs of the timepiece mechanism.
Therefore, the watch is wound up bit by bit with every movement of the wrist.
Manual winding is always available
Manual winding is always available with automatic watches. Due to the fact alone, that the watch can not be put into operation through movement at the beginning of its activity and after longer rest periods.
Therefore, the basic principle with all watches without access to electricity is always the same. A spring is stretched through mechanical energy. The push of this spring, in attempting to come back into its starting position, produces a force. The force, controlled, is used to drive the hand. Intermediate instances cause the hands to flit at the correct speed over the faces, such as gearing, suspension, barrel or wheelwork.
One thing, however, is always the same: the hands go in a circle!
