Both men and women throughout the world usually wear a suitable watch in order to view the time, at any given moment; and at any place indoors or outdoors. Moreover, it is also worn as an accessory. In the earlier days, people generally wore mechanical watches. They were initially hand operated and relatively difficult to use, as the time had to be set regularly and frequently. Hence the automatic models were manufactured, that functioned due to mechanical vibration. And later on the electronic watches were introduced, that used electrical oscillation. The balance spring electronic watch primarily had a watch balance wheel, instead of the electromagnetic winding drive to balance the spring. The oscillator was powered by small batteries, and operated by an electronic circuit. They were followed by the electronic tuning fork watch.
This watch had a metal tuning fork oscillator, and an electronic circuit that provided the output pulse current, in order to vibrate the mechanical tuning fork and the simple pendulum wheel. The oscillator circuit or liquid crystal circuit of the electronic watches consisted of inductors and capacitors. However it had an unstable frequency, hence they were soon replaced by the quartz crystal oscillator, which had a stable frequency and oscillation. These liquid crystal watches basically had a thin quartz chip or plate. And their piezoelectric effect and piezoelectric resonance; helped to produce highly accurate quartz digital watches.
China Watches
The mechanical watches are now replaced with the emergence of the quartz digital watches, as they are very precise, simple to use, and also easy to maintain. A quartz watch actually functions on a vibrating crystal. It uses a crystal film to produce the oscillation and provide the exact timing. The external crystal responds to the voltage and generates distortion and stretching. This in turn, produces electricity at both ends of the compressed crystal and enables it to oscillate constantly.
Nowadays, a wide range of made in China watches are available in the market. In fact, they are pretty good gifts for your family, friends & children. The latest variety of china watches also includes the unique wrist quartz silicon band watches. It looks very attractive due to the three ornamental set of colorful buttons on the right side of the dial. The exclusively designed dial has six Arabic numbers; and the accurate movement of this stylish gift watch assures a high level of accuracy.
Moreover, it has a very tough stainless steel back cover, and the required size of batteries is also provided for immediate use. Besides the elegant silicon wrist band of this made in china watch is very comfortable, and can be simply fastened with a modish buckle. It is an ideal choice as a watch gift for people of all ages. They are readily available in many beautiful colors such as blue, brown, black, pink, purple, red, white, etc. Hence lots of people now prefer these china watches as a gift for friends, a gift for family, and also as a gift for children.
