I want to tell all my experience, playing with the idea of this clock to Buy. I have always had a Casio clock and after the last unfortunately broken leaves, I decided quickly for a clock of this company. First, the clock was delivered very quickly, as you are used to it on Amazon. First impression was very good, the bracelet could be quickly and easily adapt to my arm (1 link removed) and made a figure in the arm. After some time, unfortunately I had to realize that the watch glass is totally scratched. And no I do not work at the construction site. (Office job). I wonder where the scratches come. But well with the scratches I can live (does not affect the functionality is used). But what an absolute NOGO with this clock is the buttons on the right side (I wear the clock left) are mounted so unfavorable that they are operated at the bend of the wrist. The light (button top right) is less serious than the bottom right to select the time zone. So it is on the clock at a time 1,2,3,4 hour (s) later ????? I have the Zeitz horsegram asked all to UTC me, but you have to scroll constantly to time zone 1 to display the current date, very annoying. Therefore, I advise my side clearly on the purchase!
