Lange 1 Perpetual Calendar Salmon Dial — 345.056

Merging a perpetual calendar with the Lange 1 dial was Günter Blümlein's early idea, but a notoriously difficult design problem. Since the defining big date couldn't move, adding day and month indications without breaking the collection's rule-of-thirds symmetry seemed impossible. The project sat shelved until the 2010 Daymatic’s mirrored layout provided a template: a peripheral month ring rather than another dial aperture. Lange launched the result in 2012 as the Lange 1 Perpetual Calendar Tourbillon, introducing this non-tourbillon version in 2021 at a drastically lower price.

While its white gold case is common for Lange, reference 345.056 is defined by its a rare sight, a pink gold dial. A tone Lange almost never uses, and reserved for only the highest complications. Limited to 150 boutique-only pieces, it launched in 2021 for $116,000 and sold out within months, with retail climbing past $140,000.

The result is one of the market's cleanest perpetual layouts. Bypassing traditional aperture style, the month sits quietly on that peripheral ring, leaving the classic Lange 1 face intact: off-center time, big date, and small seconds. This generation also integrated a day/night moonphase, pale blue by day, starry dark blue at night. Set within recessed, guilloché sub-dials, it adds a sense of depth that flat perpetual dials usually lack.

Underneath is the caliber L021.3, based on the Daymatic's automatic architecture and built as a single integrated movement rather than a module bolted onto an existing base, unlike most perpetual calendars on the market. Every indication switches instantaneously at midnight, including the month, which is the harder problem to solve. A conventional perpetual calendar advances the month with a light 48-tooth wheel. Here, Lange has to rotate a full peripheral ring by 30 degrees on the last day of the month, roughly four times the travel of that small wheel, and do it in a single, snapping instant. It runs at 21,600 vibrations per hour with 50 hours of power reserve. Even the rotor, a solid gold, machine relief-engraved piece with a platinum centrifugal mass and a skeletonized ARCAP center, is finished to a standard most brands reserve for a hand-wound caliber.

This example is in very good condition and comes with its original box and papers. Available at The Selection, at Langepedia.com.
