Time signal from the GPS satellite, energy from the sun

Haptic and optical is the Citizen CC1084 a high-end product: EcoDrive Solar, sapphire crystal, titanium case and bracelet. Super processed. The case is compared to its predecessor CC1054 minimal small and flat, which makes the clock even more portable. It is "only" a water resistance of 10 bar (instead of 20) indicated, but that seems relatively unimportant. With two, you can swim and snorkel, dive with neither of them in the deep sea.

I own a number of "normal" Citizen and Casio radio watches that yes every night receiving a signal from a long wave transmitter station. In Europe, it is in Mainflingen near Offenbach. Who in a range of about 1,500 kilometers (ie from South Scandinavia, western Russia over Northern Spain to France) lives, always has the exact time - including winter / summer time changeover. In Germany, it works without any problems. When time zone change, however, is a manual long-wave reception, especially during the day, more than troublesome - if it works at all.

The Citizen Satellite receives the time signal on the other hand the world of GPS satellites. If the businessman times just from Frankfurt to Timbuktu to Tokyo to Sydney to New York and then flew back to Frankfurt, he has at a given airport just quickly set the current site, look for a clear view of the sky, the bottom button press for 2 seconds , the arm stretch (close to the body of the receipt does not work well), and then wait about 10 seconds - already he has the current time.

So everything was great, better, great? Not quite, the GPS signal does not include summer / winter time, this must be the end of March / Oct always set manually - but only takes a few seconds. In addition, the automatic nightly update eliminates, the reception is carried out exclusively by hand. So you have a quasi Solarzuhr that you can update in a short time worldwide.

Conclusion: If you constantly shuttling between time zones, this clock can really make good use of. Who lives in central Europe and is more fixed, they do not actually need, but may participate in the great engineering / optics / haptics delight. Or save a lot of money and buy a "normal" clock ;-)
