Step 1: Pull out the crown, stop all hands of the watch and enter the state of "adjusting time". Adjust the time to six o'clock sharp at this time. This is done to avoid damaging the date module when adjusting the date after one week.
Step 2: Push the crown back to the state of "adjust date and week". At this point, the hands of the watch start to turn normally and can be ignored.
The third step is to adjust the date and week. You should adjust your watch to the day before the watch date. For example, today is Friday the 29th. If you adjust your watch now, adjust the week to Thursday and the date to the 28th.
