The second crown, located at 9 o’clock, has only one position and is used to scroll through the lunisolar
calendar in both directions. In other words, it moves the hand, which has a sun-shaped end, to a cho-
sen date on the outer concentric zone of the dial in which the 12 months of the year are indicated and
the days of the month symbolised by two rows of indices, (the inner zone shows the odd dates and the
outer zone the even dates) The SunMoon mechanism directly calculates the position of the other hand
showing the lunar indications.
