I wear the clock for a year and a day have to say, it complies in all respects except for one all my expectations. The clock looks good, is easy to maintain, is exactly, you do not need battery replacement more and the time zone change is perfect. However, I would buy more the clock again under any circumstances. The problem for me is the crown. That this sometimes pushes back of the hand is now not a big problem, but a little, which is quite annoying. But, the crown is not screwed. The crown is also the reason for this recession. Last summer I missed an important appointment because I am stuck with the crown and she had pulled out. At once the clock has moved. Well, I thought, may indeed times. This morning, it is me but 3 x happens that the Crown has withdrawn. Conclusion: for a clock in this price range, it is incomprehensible to offer no screw-down crown Without exaggeration, one can say that the clock is adjusted to an average 2 times a month unintentionally.
