Upon receipt of the radio signal, the clock has apparently no problems, not even in our broadcasting studios, where I often have no or very poor cell phone reception, because everything is crammed with technology. I can at any time compare with our own watches; after three days is certainly no difference detected, I could see with the naked eye. I also find that the clock including bracelet looks comparatively elegant; In any case you will find for the ridiculous price guaranteed nothing better. The appearance was the equivalent here already pointed substantially in the photos, except for one small detail, to: namely the word "PEARL" above the date line, only on a picture (the hand or the forearm) to see the is nowhere else. I find but not annoying.
I can not say anything, because I do not use more than the other functions. I do not need a stopwatch and prefer as a mobile alarm clock my smartphone. And since I more of a "paper pusher" career - or even a "microphone perpetrators" - am, I'm not so worried because of the robustness.
The readability of the display is very good, everything is good to recognize (the day of the week as I wear glasses should take a closer look, but I know anyway mostly), even if it looks at an angle or right angle from the left. Even oblique folds from the top, just diagonally from the bottom not because one sees then only eights. But who looks already inclined to his clock? The date in US format (only month, then day) bother me any more than the Umsztand that for the clock the week with Sunday starts instead with Monday.
All in all I'm very happy with the little gem and would recommend it only!
