The undisputed star of A. Lange & Söhne’s 2014 collection, the Richard Lange Perpetual Calendar Terraluna is remarkable on many levels. Beginning with its most obvious characteristics, it is the first Richard Lange model to feature a the signature Lange outsized date. Like the Richard Lange Tourbillon “Pour Le Mérite” of 2011, it also adopts a regulator-style dial design.
The inspiration for this comes from one Johann Heinrich Seyffert who made, in 1807, a world famous regulator which resides today in the Mathematics and Physics Salon in Dresden. Seyffert had been instrumental in transforming Dresden into a hub of precision horology in the early 19th century.
