A clock for people who do not give up quickly

After a long wait came the "clock" at last from China. After unpacking I am because they desperately ask for. Since no description was there, I started to try. It was the accidental discovery that the light sensor is used for setting, brought the breakthrough. The analog section can be used only as an animation, because the time set too easily adjusted even with a light touch of the button. The date is displayed only briefly, when you press the light button. Also, the alarm is turned off with the light button and. No 24-hour display possible. The date format month / day can not be changed. I had ordered the clock as "work watch", which should not be expensive. But as I move at work, there is a danger unwittingly the time to adjust. Not bad as it is Kinderuhr that can press like knobs and look forward to the change of light. Who needs a clock to the time to know the move reliably, this thing should not buy.

The clock can be switched to 24 hour display, but do not ask how!
The knobs adjust not as easy as I had first feared.
The clock still does its service, the bracelet also.
