Indicating the date (G). 

Indicating the day of the week (H). 

Indicating the month (J). 

The date is shown by the position of the blue pointer G which moves one division every 24 hours; it is set by pressing the pusher K. The day and the month are shown in the 2 dial openings. The date changes automatically every 24 hours. The month, however, is set by hand. The day of the week is altered by lightly pressing the double-action pusher L; the month is altered by full pressure on the same pusher. 

The calendar mechanism is usually set by means of pushers on the side of the case. However, as there is no standard arrangement of their positions and corresponding functions, they are not necessarily the same as those shown above.

G = Date

H = Day indicator

J = Month indicator

K, L = Pushers for setting calendar mechanism
