How to set the time, date, and day of the week

1
The watch is provided with a date and day of the week function and is so designed that the date
and day of the week change once every 24 hours.
The date changes around midnight, and the day of the week changes at around 2:00 a.m. If
AM/PM is not properly set, the date will change at 12 o'clock noon, and the day of the week will
change at around 2:00 p.m.
The day and date cannot be adjusted during the "No setting period," from 9:30 p.m. to
2:00 a.m, even if turning the crown. Turning the crown during this period will not cause
a malfunction.

time and then advance it to the exact time.
