How Are Watches Made?

A short history of watches, starting from the 15th century, shows how the techniques used to make them evolved over time. In the past watches were carried in pockets attached by a watch fob. Nowadays pocket watches are bought generally for collectible purposes or to be worn with an highly elegant outfit. The trend of the last century is wearing the watch nearby the wrist. Wristwatches are worn with a anklet or naturally a strap that can be made out of varied materials.

The movement of the watch is the mechanism enclosed in the case. There are basically two types of watches nowadays in what concerns movement. There is the mechanical watch and the self-acting one. A watch that has a mechanical movement has to be winded manually, while electronic ones wind themselves by a simple movement of the hand. In this case a quartz crystal is mounted to regulate the electronic oscillator and to help showing the time with the best accuracy possible.

Taking a look inside a watch one can see that the wheels and the other parts that are mobile stand between two plates which, with the help of a few pillars, create a scaffold for the movement. The front plate is a circular one, while the other can be shaped in varied ways. In the case of the contemporary watches, the second plate is supplanted to make the movement easier. Its place is taken by the so called bridges that are surely a string of bars.

There is also a contrast in what concerns the power source. In the case of by hand watches the power comes from a spiral string that has to be rewound after a unavoidable duration of time. The self-acting watches need a battery. Any way there are some types that recharge themselves from the movement of the hand. But in the majority of electronic watches the battery has to be supplanted periodically.

There are also watches that are powered by the sun-the so called solar powered watches. The light from the sun is converted into electricity that gives energy to the battery. This is why this type has to be exposed to the light of the sun for longer periods of time. On the other hand the battery doesn't need replacing, but naturally recharging.

In what concerns the display of the watches there are also two types: analogue and digital. The former ones are analogue, which means that it has two or three hands that rotate to show the hour, the tiny and the second. The digital type displays the time in numbers, instead of using hands.
