The clock is a little harder than I thought, but that does not bother me. When alarm points, you can unfortunately provide only forward, although the clock also controls backwards. The alarm time always refers audf the "Home Zone" and not on the currently displayed may 2nd time zone.
After 4 weeks on the outskirts of DCF77 reception the clock was about 10 sec ago.
Wichtigtste functions:
Time and date (DCF77), stopwatch, alarm, dual time, light, luminescent numerals.
