Had the clock 16 hours in use, even to view this if they do not perhaps someday the DCF signal, sadly wrong. Well, you can manually adjust the clock yes ... to instructions should the second hand stop at 12 clock when you switch to manual mode ... the pointer stayed on the 11 ... after a reset on the 5, another for a reset are on the 8. The protective glass had some minor scratches, so the clock was probably not entirely new, but was appointed as new. Probably this was ever sent back due to non functioning DCF. One thing you have the clock but let it stop there the 2nd star .. it really is as good as silently .. even moved the minute hand is fairly quiet (a little piece jumps every 15 seconds). Those who place the highest priority on a silent clock, can be accessed here happy, otherwise rather not recommended.
