Offered for sale is an exceptionally rare A. Lange & Söhne Langematik Perpetual Calendar, reference 310.021, representing the highly desirable second generation of this iconic complication.
This generation is distinguished by its refined case architecture, notably eliminating the large external corrector pusher found on earlier executions. The absence of the external pusher results in a cleaner, more harmonious case profile — widely regarded by collectors as the most aesthetically balanced and elegant iteration of the Langematik Perpetual Calendar.
Produced in relatively small numbers, examples of this second-generation configuration are seldom encountered. Finding one paired with a recent full factory overhaul makes this offering particularly compelling.
