The chronograph from Casio is a real eye-catcher at the first moment. Weight, size and design make the impression of a well-designed and robust Mens. The dial is easy to read and the time is quite accurate. In less than a week it was only slightly more than 1 sec. Back. But on the 2nd view disturb the divisions of the clock. So the large second hand is just the second hand of the stopwatch, while the actual second hand hidden at the bottom behind the remaining pointers. Even a stop time for 12h seems to me exaggerated. Because the accuracy is limited to the second particular. Much more useful it would be to me the clock for the hours since appeared save and instead display tenths of a second. The luminosity of the minute and hour hand is perfectly adequate for the length of one night and to read well enough in the Insität even after several hours. Conclusion: A chique clock with some unfavorable execution in technical design and therefore highly recommended for the price only partially on.
