Lack of finishing

The design of the watch is not bad (very athletic). Unfortunately, the face of the current date and the day of the week is not working properly. Indeed, by late afternoon, the needle already happening in the next day's date and in the evening, this is the day hand that goes to the next day. Worse, if we do nothing, we gain 2 days (at the time) as you go.
Fortunately, the time is correct.
Chinese watch that is not worth its price.
