Within a week use I can say that it has been a good companion.
At first I had a little trouble finding zuzubekommen the bracelet on and arrange the clock. But even without instructions, I could get used to get used to the "buckle".
Operation is simple. A press of the top button "wakes" at the clock and it displays the time. If you press the button again, the date is displayed. The third keystroke you see the seconds of time. "Additional Features" as stopwatch, countdown or clock does not have to provide the clock. After five seconds, the clock will turn off again. With the lower key to get through the Settings menu where you can set the time, date and time format (12/24).
Are there any weaknesses? Yes, the bracelet can neither shorten nor lengthen, but is okay in length for most people. I would have wished a little shorter, but also 3 cm further up my arm sits the clock comfortable and easy to read.
Speaking of readability, under a sleeve of a shirt or a shirt can be the clock thanks to the LEDs read well, very convenient! Even in normal daylight the clock is read out, how I can look it directly under a bright summer sun too early to say at the time.
Can recommend with a clear conscience the clock!
