The calibre 565 is based on the 563 which has 17 jewels compared to 24 in the 565.

Some of the topics covered in this caliber listing:

Adjusting the Date:

Important: The parts that make up the quickset mechanism in the 565 are prone to breaking if the date is changed while the hands positioned between 9:00 PM and 1:00 AM. For that reason, DO NOT attempt to adjust the date during those times.

To change the date, pull the crown out one click (time-setting mode), then pull crown again and the date will advance. Pull, push, pull, push, until you reach the correct date.
