Adjustment knobs unfortunately everyday unfit

First, however, I have tested the clock on their Altagstauglichkeit and am looking for the adjustment knob for the week almost desperate. In the meantime, I thought, the hour hand must be repeatedly turned further 24h. That this is not the case, I noticed on the bad instruction manual. While this means that somewhere there must be a button that changes the day of the week, but this is where she leaves. In fact, there are two left recessed buttons, one of which is apparently inoperative, but the other one fulfills this purpose.

That you have to continue to push the date each month (the display goes to 40) I see as a problem to. Finally, it is only once a month. Much more problematic, I find the small resistance force that is necessary to change the date and the month. Unfortunately, it is not unheard of in everyday life that evening another date was set. I suspect that I have the buttons have been pressed by mistake during the day. Especially when one digs a little from his pockets, it happens sometimes. Me personally disturbs not serious because I can defer the date by a few clicks, but for the price (250 a month ago, today 150) I expect better.

The wristband is unfortunately a bit too short. As a full-size and -gewichtiger man I get the bracelet around my wrist while, but I had to choose the penultimate hole already. People with a thicker wrist are therefore get the clock difficult closed or they will tighten. A one or two centimeters longer bracelet here would be desirable, in particular because there will still not be too long for people with a smaller scale.
