The “cathedral” gongs
To optimize the acoustic quality of a minute-
repeater wristwatch, the “cathedral” gongs
are shaped to encircle the movement not just
once, but nearly twice. This makes them almost
twice as long as conventional gongs. The result:
greater vibrational stability and better acoustic
characteristics.
The perpetual calendar
The perpetual calendar indicates the date, the day
of the week, the month, and the leap-year cycle,
automatically taking into account months with
28, 29, 30, and 31 days. It switches directly from
September 30 to October 1 or from February 28
to March 1. In leap years, it indicates February 29
before switching to March 1.
If the watch is worn regularly or kept in a winder,
the perpetual calendar mechanism will require
no manual correction until February 28, 2100, a
secular year in which, as an exception, February
29 is skipped.
