In addition to the time, the very legible rhodiumed silver dial of the Saxonia Annual Calendar indicates the date, the month, the day of the week, and the moon phase.
A mechanical program assures that the different durations of the months with 30 and 31 days are always correctly displayed throughout the year. The date must only be advanced once a year, with pushbutton ease, at the transition from February to March. If the watch has been set aside for a longer period of time, the calendar indications and the moon phase can be updated with recessed push pieces.
In addition to the combination of an annual calendar and the Lange outsize date, the Saxonia Annual Calendar features an exceptionally accurate moon-phase display. It only needs to be corrected by one day every 122 years. The watch is driven by the self-winding SAX-0-MAT calibre. Its patented ZERO-RESET function makes it easy to accurately set the time.
The movement is visible through the sapphire-crystal caseback. Ample power is delivered by the bidirectionally winding rotor in 21-carat gold. The centrifugal mass in platinum on the outer edge of the rotor adds extra inertia. The rotor is positioned such that it does not obstruct the view of the beating heart of this watch: the classic screw balance. It oscillates beneath the manually decorated balance cock: the master engraver's artistic signature makes each watch unique.
