1815 ANNUAL CALENDAR and SAXONIA ANNUAL CALENDAR

The Saxonia Annual Calendar is a second model to be recently released along with the new 1815 Annual Calendar. Collectors now have the choice of two exclusive watches with a calendar feature.

The calendar indications of both watches only requires to be manually corrected once a year – at the end of February. The moon-phase displays are calculated to an accuracy of 122.6 years. Both models come in white- or pink-gold cases with argenté-colored silver dials and are endowed with manufacture calibers lavishly finished to the highest standards of Lange artisanship.

The Saxonia Annual Calendar is powered by the self-winding SAX-0-MAT movement. Suspended in ball bearings, its gold rotor with the peripheral platinum centrifugal mass efficiently transforms the kinetic energy of every arm movement into mainspring winding power.

The Zero-Reset function, the Lange outsize date and a clearly organized dial with gold baton hour markers elevate the 1815 Annual Calendar’s appeal to purists who prefer to regularly impart power to the manually wound movements of their watches by hand.


The mainspring barrel of the classic calendar watch has a power reserve of three days. An analog date, Arabic numerals and a railway-track minute scale are traditional design elements that graced legendary pocket watches.

Both the Saxonia Annual Calendar and the 1815 Annual Calendar retail at €37,500.
