The entire calendar is now automatically set correctly. There is no need for you
to know the current phase of the moon or whether you are in a leap year. You
do not even need to set the day of the week. This simplified setting is very con-
venient, particularly if you have not worn your IWC watch for a few days.
Moon phase display
The moon phase display is automatically set by the calendar so that it is
always correct. The transmission ratio is so precise that the display deviates
by only a single day after 122 years.
Reading the chronograph

onds hand runs around the edge of the dial.

tion with a continuous hand is situated on the subdial at 6 o'clock.
