Not long ago, watches were used exclusively for the measurement of time. Today, almost any appliance, starting from the mobile phone and ending with a refrigerator, equipped with an electronic display having such a function. Now, from the device for determining time they have become a fashion accessory that can tell a lot about the status of its owner. Therefore, they have to be approached responsibly to the choice. There are several varieties of watches: mechanical, quartz, digital watches.
How does it work? The principle is similar to the watches of operation of electronic devices typically quartz movements. In the heart – an electronic unit which feeds pulses engine, and that in turn, rotates clockwise. The source of fluctuations is a quartz crystal, hence the name. It differs only in the way to output the data on the dial. At its core, the electronic watch is a mini-computer with a chip, which handles the crystal oscillator signal and displays the information on the display.
Digital watches casing may be made of stainless steel. The metal is durable, wear-resistant and is hypoallergenic. In addition, it differs with a low cost. Often, for decorative purposes in the steel hull plating is applied, which gives it a more refined look. Housings sport models often made of plastic. It has absolutely no effect on their functionality. It sports electronic watches are often subject to heavy loads. Titanium alloys are also popular. They measure light, but durable and pleasant to the touch.
As for the strap material of digital watches – preferably leather, metal or rubber are selected. Do not dwell on the plastic or silicone models – they do not last for long. Leather Strap looks presentable, but its life is not long. About a year later you will have to replace it. Metal bracelet will go perfectly with any way, whether it is jeans, a business suit or a dress. And it is guaranteed to last for many times longer. It is necessary to choose a bracelet consisting of cast links.
Digital watches are watches in which to reference time periodic electronic oscillator is used, converted into digital signals, repetitive 1 second, 1 minute, and 1 hour. Signals are output on digital display showing the current time, date, month, year, day of the week.
