Solar-powered watch “is a built-in light energy into electrical energy watch system due to the use of having to waste battery, you can save the limited resources of the earth, reduce pollution, is truly environmentally friendly products.
Light energy wave form through the watch’s built-in radio receiver and antenna to receive “standard time” radio waves emitted by the towers, get time and calendar data, automatically correcting the watch time and date. Standard time signal is a high precision and high stability of the cesium atomic clock as the signal source, a second error hundred thousand years.
Lightwave watch beyond the Vacheron Constantin, Polaroid Jue, Rolex, Omega watches and other foreign old brand. Citizen watches all use radio light energy technology, the use of any visible light as an energy source drive. As long as there is light energy, as long as it can receive the error will never have. First only light energy wave form was developed by the Japanese citizen in 1995. Market price of RMB 2000-5000 models are, of course, there are other brands and terminologies, such as Casio, called solar radio table.
The principle of Lightwave Watch
Standard radio signal transmitter in accordance contain “Time Code” waveform signal is calculated and converted to time display.
1, the so-called “Time Code” by “year, month, day, week, hours, minutes and seconds” and other elements of time, the signal is then received by the receiver of the watch.
2, the receiver the received signal is converted to a time pulse signal watch.
3, watch the pulse signal and the newly received pulse signal for comparison, there are errors corrected time, so watch always remain accurate.
Standard time radio signal by the Chinese Academy of Sciences National Time Service Center affiliates (NTSC) in Shangqiu City, Yucheng County, Henan Province, established a civil standard time radio transmission tower; signal range covering most parts of China, Tibet, Xinjiang and other remote areas temporarily unable to collect to. In North Korea, South Korea and the western region of Japan is also able to receive radio signals emitted by the tower.
How to receive Lightwave Watch information
a, press the button to force the signal reception: the received signal is mandatory when the user considers it necessary, the signal can be received at any time manually correcting watch time and date. Due to different environments, reception of the signals will be different. Strong and stable signal receiving time can be completed in about 2 minutes; If the signal is weak, poor environment, you need about 15 minutes.
b, automatic timing of the received signal: Citizen Eco-Drive watch radio clock receiver set time is 2:00 or 4:00 each receiving one. Less in this time period the standard radio signal disruption. If the recipient successfully in 2:00, then 4:00 no longer receives; if reception fails 2:00 to 4:00 when automatically re-received again.
After c, power runs stop watch rechargeable automatic restart after a received signal.
How to determine whether to receive success
If the second hand moves to the “H, M or L” in any position, it indicates the reception success. Radio wave reception by environmental and meteorological conditions influence. In case there is a barrier, there may not be received. If reception fails, the second hand will point to “NO”, then replace the receiver to adjust the location or receiving direction (direction towards Henan), and then forced to receive.
“Solar-powered watch” is a built-in light energy into electrical energy system watch. Due to the use without having to waste battery, it can save the limited resources of the earth, reduce pollution, is truly environmentally friendly products. In 1996, Japan made the watch industry’s first “green products marked” finds
2001 was the Chinese watch industry’s first “environmental labeling products” certification. Not only to achieve a “light-driven watch,” and, rechargeable batteries no longer use mercury, cadmium and other harmful metals. And manufacturing products also avoid the use of fluorine materials and other harmful substances, by a variety of strict criteria for the determination.
Purchased in China radio watch, whether the use of foreign stations transmit signals? Different frequency signals transmitted each signal tower. In the Chinese market sales of light energy wave form, and some can only receive standard time radio wave signal Shangqiu towers. But the world can automatically adjust the time Citizen light energy wave form has been marketed in a foreign country, is to introduce China. This timepiece capable of receiving multiple innings, simply select the country name of the city, you can get the nearest radio signal emitted signal tower, automatically adjusted to the local standard time, for business people often cross-border travel.
