Occasional winding: if the watch has not been worn for 44 hours (cal. 1128, 2628) or 55 hours (cal. 3603) or more, wind it up with the crown in position 1.

2.Setting the time zone: pull the crown out to position 2 and turn it. Only the hour hand moves (clockwise or anticlockwise), without affecting the precision of the minutes or seconds. If the hand moves past midnight, the date changes automatically. Push the crown back to position 1.

Setting the date: pull the crown out to position 2, turn it forwards or backwards to change the date each time the hour hand passes midnight. The date moves forwards (or backwards) one day. Repeat until the required date is obtained. Push the crown back to position 1.
