History and info

 

Junghans radio-controlled clocks and watches. Their technology makes them one of the world's most accurate.

Junghans radio-controlled watches adjust automatically via radio signal to transmitted time of one of world's most accurate clocks, the cesium-based time of the Physical Technical Federal institute in Braunschweig. With a devia-tion of 1 second within one million years! .

The secret of their accuracy?

A receiver system, mini board with microprocessor and a regulating and controlling device The cesium time-base transmits a so-called time-telegram to the time-signal transmitter DCF-77 in Mainflingen nearby Frankfurt. The transmitter broadcasts the coded time-telegram over the long wave of 77.5 kHz. The receiver system of the radio-controlled watch receives the time signal, which is then decrypted by the microprocessor and passed on to a step-ping motor to adjust the watch with absolute accuracy.

ontinuous reception within more than 1,500km range around the transmitter DCF-77 is guaranteed. Outside of the range of reception, the watch works like a standard quartz-watch in the event of reception interference a functionality check can be performed by activating a transmitter call button, upon which the watch automaticalIy self-adjusts again.

Thus the accurate display of the statutory time is guaranteed. Radio controlled clocks and watches by Junghans are great - yet just an element of a genuine broad product range of solar- and quartz watches. Clearly cut and designed, structured through Junghans' brand triad, it represents the watch maker competence of the company.

The competence, which makes us proud, and which urges us to carry on at the same time. Because: time moves us.
