THE PERPETUAL CALENDAR
This clock is equipped with an in line Perpetual Calendar that indicates
the Day, Date, Month and Year. When the clock is working, the display
of the Julian calendar is done through jumping discs.
The energy is accumulated by a mechanical system throughout the
day and then this energy is released at midnight allowing discs to jump
from one indication to another instantly.
When the clock is stopped for some reason, setting the calendar is
done at the same time as the time setting. The calendar is therefore
leaping forward.
