The clock is worth the money, but more expensive, they should not be. I'm unpacking shocked how big the clock. That she would be quite large, I had taken the previously read a review, but 52 mm in diameter take quite large even at my not exactly narrow wrist. Did I read that, or was not it at that? Anyway, had to listen to me is that I have now bought an extra large Senior clock (I'm only 63 :-)). The clock works fine, the selfwinding well enough when I discard the clock at night. The clock is slightly ahead, beginning approximately one minute per day, now it seems more accurate to go, I have the time not corrected a few days. The time is very easy to read. For the date you can not say, unfortunately. The date display is compared with the weekday display set back, which is why you can only read the number in the little window to when you actually plan just looks. The Zusatzzeigerchen have only limited benefits. Instead of the 24-hour clock it would have (if I have to, anyway) an am / pm indicator done. The ads for the month and the year I find useless. Perhaps they will help you so, if you wake up again after a prolonged coma. The annual display I can at least see how long it is until retirement. After all, the clock looks through the auxiliary displays interesting, and they do not interfere, too. The clock is all quite useful in particular, and I will use them the next time.
