In the clock, I can not say much. I had researched long, originally wanted another one that would have been, however, to order only in Japan under immense cost. Eventually I found the GD 100-1BER, ordered, absolutely happy. Who has trouble reading, should simply take no inverse display, no matter what the clock. I have therefore no problems during the day anyway. The inverse is finally the kick on the display and many times more elegant than the standard display. The lighting is gorgeous, either by pressing a button or for a 6h timer automatically adjustable (turn itself off to conserve battery life independently again). The clock is always supported, of course, playing sports and swimming. At the clock and whistles is so much available, incredible, I still can not memorize all the functions.
Those who wonder why in extreme cold, the display fogs: do not panic, the clock is not leaking! Such products are usually produced in regions where there is a slightly higher humidity. And is thus also present in sealing within the clock. Cools the clock from extremely condensed from the water and steam up the screen from the inside. But not so bad, when it gets warmer in the pocket or in the apartment, which has disappeared in a few minutes to seconds.
Finally hold the G-Shocks deliver what they promise. The clock was sometimes even half-heartedly thrown across the room .. itches housing not give a damn! Another (not mine) has also been intentionally thrown against tiles ... nothing happens! Those things are "indestructible" ..
