The decisive point: after just 3 weeks of sporadic use of the clock already no longer displays the right time. Over a period of 4-5 hours already lags the clock about 10 minutes afterwards, when the clock one day running, the time display does not to nearly an hour ...
Today alone I have the clock now 4 x readjusted (time compared with cell phone and laptop).
Battery is not empty.
After perpetual check, I've found that if you can be quiet the clock for a long time (days) and does not move, the clock is running properly. Once the clock is but worn - or else moved, then the clock is ticking for the shortest time to minutes afterwards (fe you put these in a bag or backpack.). Loss of time up to an hour throughout the day.
CONCLUSION: scrap; Return to Sender after 4 weeks.
