Caveat: Beautiful clock, comfortable to wear, not too bulky on the wrist. Negatives: Instructions is a joke. The most important should be mentioned in the instructions, which is the crown before you can use it to unscrew. From setting forth the clock is more of a nightmare. Time and date ok. but to bring the stopwatch hands on fundamental values, you spend hours (NO JOKE). Did the so calm, because I need need and no other bells and whistles the clock only for the basic display. And can the clock really good.
