At a first glance, the new 1815 Annual Calendar represents a proof of craftsmanship, with a good impact and a complication presented in a classic way. In terms of functions, the watch itself is a true masterpiece.

Comparing the 1815 Annual Calendar with the Saxonia Annual Calendar, there are some similarities that can be observed: the calendar indications of both watches needs 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-coloured silver dials and are endowed with manufacture calibres lavishly finished to the highest standards of Lange artisanship.

But the new features for the 1815 Annual Calendar are also noticeable, both in terms of design and functions.

First of all, there is a the date – the Saxonia model presents an outsized date, while the new model features a manually wound movement and an analogue date, following the classic design and style principles of the 1815 watch family.

Then the sizes are also different, the new model has a 40 mm diameter case (white gold and rose gold versiosn) and the Saxonia watch has a 38.5 mm case.

And another difference between the two watches is at the movements. The 1815 Annual Calendar is powered by a manually wound movement, while the movement for the Saxonia model is the self-winding SAX-0-MAT.

In the end, as A. Lange & Sohne representative says, the choice of either of these two annual calendar watches will be a matter of personal style, both of them having a clear and good organized presence on the wrist, with a balanced design and practical complication.
