A. Lange & Söhne Saxonia Annual Calendar in Platinum (Ref. 330.025)

Since it had its debut three years ago, the articulately designed Saxonia Annual Calendar has become a benchmark in the calendar watch category. Apart from the models in pink and white gold, it now comes in platinum as well. The rhodiumed silver dial of the Saxonia Annual Calendar delivers its information in a clear and well-organised manner.

In addition to the time, the dial of the Saxonia Annual Calendar indicates the date, the month, the day of the week, and the moon phase. An ingenious 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, by the way, 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 quickly and easily with recessed push pieces.

Besides 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 legendary self-winding Sax-0-Mat calibre is the heart of this watch. Its patented Zero-Reset function makes it easy to accurately set the time. When the crown is pulled, the movement stops and the seconds hand jumps to the zero position. Then, the minute hand can be aligned with the respective minute marker; when the crown is pushed home again, the watch will restart precisely to the second.

The sapphire-crystal caseback of the Saxonia Annual Calendar reveals the magnificently finished movement. All parts are individually decorated and polished by hand. Ample power is delivered by the bidirectionally winding rotor in 21-carat gold above the three-quarter plate made of untreated German silver. 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.
