Wireless Watches

Description :

Each clock must be set in any way. Usually this is done manually by a wheel, which provides the time mechanically, or digital clock via knobs. It is easier with radio watches.

What are radio wristwatches?
Under radio watches is meant mostly quartz watches whose time is checked regularly and corrected if necessary. Radio receives the clock signal, which sends the time. This is compared with the current time of the clock and then repaired as needed. Not digital radio wristwatches have to built an engine that determines the clock faster than the actual speed, can make to the correct time. Due to advanced technology, the technical part will be very small, so there are radio watches in many colors, shapes and sizes.

History and Development
Since there is Coordinated Universal Time, in many countries there is an institution that is mandated to determine the current time. In Germany for the Physikalisch-Technische Bundesanstalt in Braunschweig is responsible. Since 1977, the Institute shines the current time on the DCF77 on a frequency of 77.5 kHz. The time can be in the region received 2000 km around Mainflingen near Frankfurt, where the Institute. Initially, only big watches were able to receive the signal.

Wireless Watches

Only companies and wealthier people, it was possible to take advantage of the clock. Only with technological advances that allowed to build more powerful antennas in bracelet and other watches, radio watches have become a mass product that helps many a businessman to keep his appointments. And the best part is that you never face the problem is that the clock is reset when changing from summer to winter time and now faces.

Operation of radio watches
The source of all the functionality of wireless wristwatches is, as has already been addressed. Mainflingen near Frankfurt In the Institute there are three different atomic clocks. Atomic clocks are based on the wings of atoms. Since these can be measured very accurately, it would create an extremely accurate time. The three atomic clocks in Mainflingen operate independently. Using a balance of all three times, the time is calculated. The calculated time is then broadcast by radio.

The signal always sends the information for the next time minutes.

Inside there is a radio wristwatches antenna that receives the signal.

After the received data set then the radio watches. This does not happen in the same interval, in which the signal is sent. Every minute a comparison with the signal would not bring the battery operated long lifetime. For this reason, radio watches compare their time usually once a day with the signal.

Electrosmog! Radio watches are dubious?
It’s a topic that comes up every now and again. The keyword electro employs a lot of people – even here and there makes for anxiety. Any device that has something to just somehow related to electricity or radio is denigrated. It is dangerous for health.

The brain can be damaged. Are radio watches, for that matter, even questionable? No! Since radio wristwatches merely to receiver and not a transmitter, you can without feeling guilty buy a radio wristwatch. Radio watches are therefore also suitable as birthday gifts .
