A. Lange & Söhne may be instantly recognisable for icons such as the LANGE 1 and ZEITWERK, but some of the German manufacture’s most compelling creations are found deeper within its collections. Described as its “Hidden Heroes”, these watches combine highly sophisticated complications with the meticulous movement construction and finishing for which the Glashütte watchmaker is known.
Founded by Ferdinand Adolph Lange in 1845 and revived by his great-grandson Walter Lange in 1990, A. Lange & Söhne today spans six core collections: LANGE 1, SAXONIA, 1815, RICHARD LANGE, ZEITWERK and ODYSSEUS. Regardless of complexity, every Lange watch is powered by an in-house manufacture movement that is double-assembled and finished by hand.
The Hidden Heroes spotlight turns towards several technically exceptional references that may not always receive the attention of the manufacture’s better-known models, but offer plenty for serious collectors to discover.
1815 RATTRAPANTE: Mastering the Split Second
Among them is the 1815 RATTRAPANTE, a focused expression of one of traditional watchmaking’s most demanding chronograph complications.
A rattrapante, or split-seconds chronograph, employs two superimposed chronograph hands, allowing separate intervals to be measured. Lange gives the complication a suitably classical presentation through the watch’s vertically symmetrical dial architecture.
Behind it sits the manufacture calibre L101.2, Lange’s seventh interpretation of the rattrapante mechanism. Constructed with two column wheels, the movement provides a power reserve of up to 58 hours.
The result is a watch that keeps the visual presentation relatively restrained while allowing its mechanical sophistication to take centre stage.
1815 RATTRAPANTE PERPETUAL CALENDAR: Complexity Multiplied
Taking the concept several steps further is the 1815 RATTRAPANTE PERPETUAL CALENDAR.
Inside its 41.9mm case is the 636-part manufacture calibre L101.1, bringing together three significant complications: a rattrapante chronograph, perpetual calendar and moon-phase display.
The watch is offered in platinum, white gold and pink gold, with the limited-edition white-gold version distinguished by its solid pink-gold dial. Despite the amount of information and mechanical complexity involved, its classically arranged display keeps everything remarkably composed.
Its perpetual calendar automatically accounts for differing month lengths and leap years, requiring no correction until 2100. At the same time, the rattrapante chronograph allows two separate interval timings to be measured precisely.
RICHARD LANGE TOURBILLON “POUR LE MÉRITE”: Constant Pursuit of Precision
Even within A. Lange & Söhne’s rarefied catalogue, the RICHARD LANGE TOURBILLON “POUR LE MÉRITE” occupies special territory.
Since the manufacture’s modern revival, only five models have received the “Pour le Mérite” designation, a name derived from the historic Prussian order of merit for science and the arts. Lange reserves it for some of the most technically accomplished watches in its repertoire.
The RICHARD LANGE TOURBILLON “POUR LE MÉRITE” combines a one-minute tourbillon with the fusée-and-chain transmission system characteristic of the manufacture’s “Pour le Mérite” watches. The system is designed to maintain constant power delivery to the movement as the mainspring unwinds, helping support consistent precision throughout its running time.
Visually, as shown on page three of the release, the exposed tourbillon provides a dramatic mechanical counterpoint to an otherwise clean, classically styled dial.
DATOGRAPH PERPETUAL: Two Lange Signatures in One
Rounding out the selection is the DATOGRAPH PERPETUAL, which builds upon one of A. Lange & Söhne’s most important modern watches.
The original DATOGRAPH debuted in 1999 as the manufacture’s first flyback chronograph. Its name combines “date” and “chronograph”, while its flyback functionality allows the running chronograph to be stopped, reset and restarted rapidly.
Introduced in 2006, the DATOGRAPH PERPETUAL added another significant complication to the formula. Alongside its flyback chronograph, its perpetual calendar automatically displays the date, day, month and leap year, remaining accurate until 2100 before requiring a one-day correction.
Watchmaking for Those Who Look Closer
What connects these “Hidden Heroes” is not simply complexity. Each demonstrates A. Lange & Söhne’s approach to combining demanding mechanics with comparatively restrained design.
The craftsmanship continues behind the dial. Lange’s movements are distinguished by traditional details including three-quarter plates made from German silver and hand-engraved balance cocks, connecting its contemporary wristwatches with the manufacture’s historic pocket watches.
Today, A. Lange & Söhne produces only a few thousand watches annually, predominantly in gold or platinum, and has developed 75 manufacture calibres since its 1990 revival.
The Hidden Heroes serve as a reminder that beyond the familiar faces of the LANGE 1 and ZEITWERK lies another side of the manufacture—one where some of its greatest technical achievements are waiting to be discovered.
