From optical and large, the clock is quite good. The packaging a quality image. Unfortunately, the clock smells very very funny and I had to do with Parüm "wearable" for the month because the smell was also usually perceived during wear. Furthermore, were the two screws on the bracket, which is located around the dial, quite loose and had to be re-tightened so that they are not lost, and the clip will be lost. At one of the two bolts only a small bolt must be removed so that the screw can be tightened. But as I said, from the optical clock is the top and the glass turned out to be so far as scratch resistant.
