Clock Manufacturer Citizen’s history began in 1918 when the Shoskosha Watch Research Institute was founded for Japan’s soil. Shoskosha completed its first pocket fake watches in 1924, and its name was entitled to Citizen. Six years later, the company decided to change to Citizen, and introduced it the next year’s first wristwatch.

Citizen launched a first radio-wizard wristwatch in 1993, which set the correct time based on the signal transmitted by terrestrial radio transmitters. The Citizen Satellite Wave GPS ECO-DRIVE in presentation is now utilizing a signal by GPS satellites, based on which the clock is settled, depending on the location, on the right time, and the time zone automatically. That is precisely because the clock is ideal for an active worldwide who wants to leave the time setting according to the item to the clock.
Citizen Satellite Wave GPS ECO-DRIVE utilizes light energy in its predecessor in its predecessor in its propulsion power and converts through a dialog through the solar panel to an electric current that is stored in the mercury free lithium ion battery. The technology will release the batteries of the clock and are saved by a spark of the eco-drive clock batteries as much as 20 years. The clock’s operating time is fully charged with a full charged battery for up to two years, so the end of the stream will not be worried – and adds to the current clock, even if the light bulb light.
Fairy-sized dial-out sees with one glance, for hours, minutes, and seconds, but also the date and day of the week. In addition, when pressing the soft buttons, the clock displays the visitor, time zone, summer / winter, as well as the Eco-Drive charging and satellite reception mode. The clock automatically detects 40 time zones, but setting the zone, along with other settings, manually manually manually with the softkeys and knobs.
Satellite reception works naturally best outdoors when there is an unobstructed view of the sky. Then it also works considerably faster than, for example, indoors at the window. If you wish to activate the function, and the clock will display the reception success with a secondary address. Receiving the time takes place in its fastest, optimal conditions, in three seconds, making it a receiver of the world’s fastest GPS time. Sijanni, i.e., the time zone determination takes up to 30 seconds.
Citizen Satellite Wave GPS Eco-Drive always stays in the right time when satellite reception is possible. If the reception is prevented for some reason, the monthly resolution of the clock is +/- 5 seconds, at normal operating temperature. The calendar has been programmed to take into account the breakpoint days and years until the end of February until 2100.
In winter, the dark north hall may come to mind the question: The clock works in the summer, but how long and dark during the winter? Since the light source is also invalid for artificial light, then the clock is charged from the seasons and irrespective of the sun. Loading, however, is needed in a rake, because the full charged clock is up to 720 days, ie about two years. To download one day from the front flow, the clock needs in sunny weather for three minutes, in cloudy weather for 25 minutes, and in the normal indoor lighting 7.5 hours of direct light.
