Bought as a "Christmas present" the clock. As such, the clock is very nice, stable processes and high quality. I particularly like the high contrast between pointers and clock that will make a very easy read. The H3 elements are indeed seen only in the dark, but then they come into their own. Reading in the dark is no problem, the brightness is enough even out to some "lighten" the vicinity of the clock. Unfortunately, the central second jammed repeatedly and unfortunately more and more often - and after a few days of wearing. The clock has not been charged or used in extreme sports. Actually, I would have expected that you exchange me the clock, but that was not the case. Instead, I should send away the clock repairs - (!) Which lasted from January to March. In my opinion a very unfriendly behavior, especially as I was repeatedly put off. By the way, another defect was discovered, which was "even" repaired. Whether it was the also exchanged battery, I can not judge. After all, since the clock works fine and accompanies me every day without problems.
For the clock to be I would give it 5 stars - it met my expectations - for the service of the dealer and the manufacturer is 0 (zero)! Points.
