1815 ANNUAL CALENDAR

An ideal companion for every day

The 1815 ANNUAL CALENDAR is the second A. Lange & Söhne timepiece endowed with the eponymous function. But in contrast to the self-winding SAXONIA ANNUAL CALENDAR with an outsize date presented in 2010, this model features a manually wound movement and an analogue date, following the classic construction and design principles of the 1815 watch family.

The 1815 ANNUAL CALENDAR timepiece in pink gold with moon-phase display, 72-hour power reserve and analogue displays for the date, day of week and month.

With analogue displays for the date, day of week and month as well as a moon-phase display calculated to remain accurate for 122.6 years, the 1815 ANNUAL CALENDAR is an ideal everyday companion. An elaborate mechanism automatically recognises which months have 30 and 31 days. The date display must be adjusted only once a year, at the transition from the last day of February to the first day of March.
