Three new timepieces—the Lange 1 Tourbillon Perpetual Calendar “Lumen”, Saxonia Annual Calendar and Cabaret Tourbillon Honeygold—affirm A Lange & Söhne’s position at the very apex of German watchmaking
At A Lange & Söhne, every watch—no matter how vastly different—exemplifies its philosophy of clarity and precision as well as its obsession with finishing. Such is the case with its latest novelties, which find the German manufacture exploring very different corners of its watchmaking identity. There is serious mechanical ambition in the Lange 1 Tourbillon Perpetual Calendar “Lumen”, classic Saxon refinement in the Saxonia Annual Calendar and a fresh take on a modern Lange icon in the Cabaret Tourbillon Honeygold. Together, this trio shows a manufacture equally capable of pushing technical boundaries, refining timeless elegance and building upon its own milestones.
Unveiled at Watches and Wonders Geneva 2026, the Lange 1 Tourbillon Perpetual Calendar “Lumen” brings two of haute horlogerie’s most demanding complications—a tourbillon with stop seconds and a perpetual calendar with instantaneously switching displays—to one of modern watchmaking’s most recognisable designs. Featuring a 41.9mm platinum case and limited to 50 pieces, it takes the distinctive asymmetric dial layout of the Lange 1 and gives it a darker, more technically charged presence.

Built around contrast and transparency, the dial has a coated sapphire crystal surface that allows ultraviolet light to charge the luminous elements beneath, keeping every indication legible in the dark. The outsized date glows dramatically, as does the luminous moon‑phase display with an integrated day/night indication making its brand debut. The celestial disc completes a clockwise rotation every 24 hours, shifting from a bright sky by day to a darker, star‑studded one by night—a mesmerising backdrop against which the moon waxes and wanes with an accuracy that requires correction by just one day in 122.6 years. In place of a conventional sub‑dial, the months are presented on a rotating peripheral ring, keeping the display clean despite the amount of information on show.
At the heart of the watch is the newly developed self‑winding calibre L225.1. Comprising 685 parts, it brings together the perpetual calendar, moon‑phase display, outsized date and tourbillon with the house’s patented stop‑seconds mechanism, allowing the balance inside the tourbillon cage to be halted for precise time‑setting. Visible through the dial and caseback, the movement reveals A Lange & Söhne’s full finishing vocabulary: perlage, solarised bridges, black‑polished steel tourbillon components and hand engraving. Its central rotor, in white gold for the first time and engraved with the brand name, works with a platinum centrifugal mass for efficient winding, while the tourbillon cock and intermediate‑wheel cock are hand‑engraved with stars and a shooting star. Standing as a final flourish at the tourbillon’s centre is a diamond endstone secured by a screwed gold chaton—an element drawn from the manufacture’s 19th‑century pocket watches.

Quiet Authority
The Saxonia Annual Calendar takes a subtler route. At a compact 36mm wide and 9.8mm thick, it is effortlessly wearable, yet commands attention. Offered in white gold with an argenté dial and pink gold with a cool grey dial, it is discreet but far from plain.
Sitting within is the new self‑winding manufacture calibre L207.1. A meaningful departure for a Saxonia complication, it is driven by a unidirectional central rotor with a platinum centrifugal mass and offers a 60‑hour power reserve. The annual calendar functionality means the display needs manual correction just once a year, at the end of February, automatically accounting for every 30‑ and 31‑day month in between. The mechanism is notably user‑friendly as well: all calendar indications and the moon‑phase display can be adjusted individually via separate recessed correctors, or advanced collectively with a single pusher at 10 o’clock.
A standout detail is the moon‑phase display that requires correction by only one day after 122.6 years. Executed in gold, coated deep blue and laser‑cut with 428 stars forming a miniature Milky Way, it brings a poetic touch to an otherwise clean dial. The recessed auxiliary dials are finished with azurage for added depth and reflection, while redesigned baton appliqués taper to subtle pyramid‑like tips. On the reverse, the caseback reveals a hand‑engraved balance cock, screwed gold chatons, blued screws and polished surfaces—elements rooted in the brand’s Saxon watchmaking tradition.

All the Right Angles
Collectors likewise have plenty to celebrate with the Cabaret Tourbillon Honeygold. Issued as a 50‑piece limited edition, it revives the rectangular silhouette—part of the brand’s history since 1997—to serve as a 29.5mm by 39.2mm frame for an incredible display of craftsmanship.
The dial alone takes several weeks to complete. Instead of printing the markers and scales, A Lange & Söhne artisans sculpt them directly from the Honeygold base, raising them just 0.15mm. After the black‑rhodium treatment, finishers meticulously polish these sections by hand to reveal the warm glow of Honeygold beneath.

Then there is the tourbillon—a small stage for hand‑finishing visible through the aperture at 6 o’clock. Its upper bridge and cage top are decorated with black polish, one of the most demanding finishing techniques in fine watchmaking that involves an artisan sliding the workpiece by hand across a tin plate mixed with special abrasive pastes, applying just the right pressure to polish the surface until it reflects light like a mirror from one angle and takes on a jet-black sheen from another. Every acute interior angle of the cage is also individually polished.
Beneath the dial, the watch carries forward a major horological milestone. When the original Cabaret Tourbillon debuted in 2008, its patented mechanism made history as the world’s first to stop a rotating tourbillon instantly for exact, one‑second time‑setting. That mechanical mastery lives on in the manually wound calibre L042.1 driving this Honeygold edition. Composed of 370 parts, it features a filigreed tourbillon cage that integrates 84 individual components while weighing just about a quarter of a gram. Its twin mainspring barrel provides an impressive 120‑hour power reserve, allowing the watch to sit untouched for days without missing a beat.
