I ordered this watch there are three weeks now and I am extremely satisfied. 1) setting a time: the hardest part because in my case it took recalibrate the needles to calibrate the zero, following a shock during transportation, but nothing serious 2) the stopwatch function, nice 3) the alarm: it just takes good eyes to adjust, the small dial is used right, a little short! 4) World Time: easy to resolve, but even dial the alarm, so farsighted refrain !! 5) put a self hour: very good, easy to do, but be outside or near a window wide open preferably 6) Product quality: beautiful, beautiful. 7) Solar System: I will judge with time .....
