If a month has fewer than 31 days, you will need to
set the date manually to the first day of the following
month. Pull the crown out to position 1. You can now
set the date by turning the crown to the left (direct ad­
vance). You should not use the rapid­advance function
between 8 p.m. and 2 a.m. because the movement
automatically advances the date during this period.
