 - The date display does not work properly. The second number shows the top half and bottem half of two numbers, instead of one number.

 - The winding button on the middle right of the watch does not work properly. I can't set the time when I pull the crown to click one, only when it is not pulled.

 - Sometimes (even when I wear the watch a long time in a row) it stops ticking. So I have to set the time about 10 times a day.
