The calendar is set by using the adequate button(s) as demonstrated in the section “Date settings”. Please notice that – depending on the watch model – the month and the year have to be adjusted manually for each turn of the month and the year; further information can be found in the section “Date settings”. Make sure that in the frame of calendar settings the hour indicator is correctly set on am and pm. This is important because the calendar functions should update the indicators once in 24 hours. In order to check this, turn the hands of the watch further than the 12 o’clock indication. If the calendar changes the indicators, the watch was set on pm. On this basis you can adjust the watch and the calendar functions correctly.
