1815 ANNUAL CALENDAR
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. The manual winder is also a subtle homage to Ferdinand Adolph Lange who in 1866 obtained a patent in the USA for his development of a crown winder that would replace the hitherto commonplace key-operated winding works.
