We bought the version with luminous hands and luminous dial. Thus we never needed electric lighting. The time was even after hours of absolute darkness still readable, just unbeatable !!! The alarm clock works with absolute reliability, making no noise and the battery lasts a long time. The time is displayed with absolute precision for years. Design? Well, matter of taste .... Unfortunately, the alarm has no stronger shocks from. Our youngest has let the alarm clock fall down from about one meter height one time. Then the hands were completely adjusted (hour hand 10, minute hand to 6). The radio link is down, and any attempt to set the time correctly failed. In addition, the clock started again for no apparent reason at beeping ... CONCLUSION: A great alarm clock (especially the version with Leutzifferblatt) as long as it is safe.
