On the quality of this clock, there is nothing to complain about. To me she is a bit too small in diameter. Certainly 40 mm diameter are given. My Swiss Clock has 43 mm. I tried to imagine the 40 mm based on this clock. Covered 3 mm can not be much. Unfortunately, like (for very smart, that's no star deduction because no quality criterion). It is with this clock is a quartz whose battery is charged by a dynamo, which is driven by the movement of the hand. This technique has attracted me. And this price is ok to come into contact with this technique. For me, however, has done the whole thing with this clock. Not because of the clock itself. This is cleanly processed and goes Quartz Typical exactly. The star deduction is for the bracelet that feels for my taste offense. Not like I expect it from a leather strap. I can not cope with the technology. When I ordered this clock, I still thought this to load the Winder my mechanical watches. Not even close. That does not work. This watch winder run much too slow to generate the electricity the dynamo. So it is to shake the clock manually. That's too exhausting. Certainly if you are carrying the clock constantly, you will not have to shake frequently. But since I have a lot of watches and I wear this on your mood, it can happen that I do not wear watches for months. Then would again hip shake. There is a charger for hybrid watches. Works on the basis of induction. Costs but the 3 times this clock. I do not want to spend. My conclusion, if you constantly transmits the clock and this clock like -> Buy recommendation. From the quality of the clock as well as the accuracy so far there is nothing to complain about.
