A. Lange & Söhne Revives The Triple Split In Platinum And Adds New 1815 Up/Down Colourways
A. Lange & Söhne is expanding two very different sides of its collection with the return of the Triple Split chronograph and new blue-dial editions of the 1815 Up/Down. One represents the manufacture’s approach to highly complicated mechanical watchmaking; the other brings a more contemporary colour palette to one of its classic dress-watch designs.
Triple Split: A Chronograph with Three Independent Split Functions
The A. Lange & Söhne Triple Split takes the traditional rattrapante chronograph considerably further. While a conventional split-seconds chronograph allows two events to be timed independently, its additional hand operates only on the seconds scale. The Triple Split extends this capability to the chronograph minutes and hours, making it possible to compare elapsed times across three separate scales.

In practical terms, the chronograph can measure two events simultaneously, even when their durations differ, with the hour counter allowing intervals of up to 12 hours. The additional functionality is controlled through the chronograph’s dedicated pushers, while the central hands and subdials provide the necessary information.
The Triple Split first appeared in 2018, followed by a pink-gold edition in 2021. Both were limited to 100 pieces and sold out, making the new platinum version a return to production after an absence of almost five years.
The new edition measures 43.20 mm in diameter and 15.60 mm thick. Its platinum case is paired with a silver-coloured dial featuring grey elements, a combination that gives the watch a restrained appearance despite its considerable technical complexity.

The caseback reveals the manual-winding L132.1 calibre, which provides 55 hours of power reserve. Comprising 567 components, the movement is assembled by hand and finished in the traditional Saxon style associated with A. Lange & Söhne.
The untreated German silver plates feature Glashütte stripes, while the openworked construction exposes much of the movement’s architecture. The result is a chronograph whose mechanical content is as important as its external design.
A. Lange & Söhne Triple Split, 424.025F. Rhodié-coloured dial, 950 platinum case, 43.20 mm diameter, 15.60 thickness, sapphire crystal. Brown alligator leather strap with platinum deployant buckle. Calibre L132.1, hand-wound movement, hour, minutes, seconds, flyback chronograph, split-seconds, power reserve, 21,600 Vph, 55 hours of power reserve. Price: Upon request limited to 100 pieces.
1815 Up/Down: A Classic Design in Blue
The 1815 Up/Down takes its name from its power reserve indication, which uses the German words “Auf” and “Ab” to indicate the remaining energy in the movement. Unlike the standard 1815, the small-seconds subdial is positioned at 4 o’clock, while the power reserve display occupies the 8 o’clock position.

For 2026, A. Lange & Söhne introduces a blue dial with bright silver subdials, a colour combination that has become increasingly recognisable within the manufacture’s collections. The new dial is offered in both white gold and pink gold, creating two distinct interpretations of the same design.
The blue surface provides a contemporary contrast to the classical layout, while the applied Roman numerals and balanced subdial arrangement retain the traditional character of the 1815 family.
Measuring 37.50 mm in diameter and 8.70 mm thick, the 1815 Up/Down remains a relatively compact dress watch. Inside, the manual-winding L051.2 calibre provides a 72-hour power reserve.

The power reserve display is particularly appropriate for a hand-wound movement, as it gives the wearer a practical indication of when the watch needs to be wound again. The movement is visible through the exhibition caseback, offering a view of the manufacture’s finishing and mechanical construction.
Each of the new blue-dial versions is limited to 300 pieces.
A. Lange & Söhne 1815 Up/Down, 244.037 (pink gold), 244.028 (white gold). Blue dial, 18k white/pink gold case, 37.50 mm diameter, 8.70 thickness, sapphire crystal. Reddish-brown (pink gold) or blue (white gold) alligator leather strap with gold prong buckle. Calibre L051.2, hand-wound movement, hour, minutes, small seconds, power reserve, 21,600 Vph, 72 hours of power reserve. Price: Upon request limited to 300 pieces each.
Two Different Expressions of A. Lange & Söhne
The return of the Triple Split and the expansion of the 1815 Up/Down collection highlight two complementary aspects of A. Lange & Söhne. The former is a highly specialised chronograph built around an unusual timing function, while the latter focuses on proportion, legibility and the refinement of a traditional dress-watch design.
Together, they demonstrate how the manufacture can explore both technical complexity and subtle changes in colour without moving away from its established approach to mechanical watchmaking.
