The Queen of faulty designs

My first clock with lunar calendar. Stop. The Second. The first "Napoli" went back because it was broken in my opinion. But from the beginning: Fast delivery - well packaged. After removing all the tapes (7 pieces) and locking ring on the crown of bracelet and clock, the lunar display on the date synchronized. This requires in the worst case, that one 30 times the 24 hour hand must turn manually before, and then again to turn so long until the current date is reached. Ok - you have to make only once at the beginning. Now the fingers were before the glow, yet fast month and day set. No problem - pull out crown - press corresponding buttons - Crown pure - all good. Forget it! All 3 Date settings can be adjusted further by pressing the buttons. So returned, because that date should not be so easy as adjusted by accidentally touching the buttons.
Clock No. 2 in record time resupplied. Exactly the same error. Or is it? Time demand at Detomaso. Answer: Nope - that belongs to ... (ok - a bit nicer paraphrased).
So this is a clock, with the one must avoid any external and internal contact possible. The best use for decoration only. What use to me a clock, when I can not be sure whether the date is correct what I see. In Month view, I could not see over it, the day should vote but already.
The most beautiful but in the end: If one of the buttons between 23.30Uhr and 5.30Uhr operated, the work may be damaged. Who does not want to ruin the clock, it is allowed to use only 75% of the day.
I'm going to now hang the clock on the wall, as a memorial German Italian-Swiss engineer confusion.
And down the instructions in advance possible load if possible.
