A. Lange & Söhne Returns the Triple Split in Platinum and Rhodium

A. Lange & Söhne’s Triple Split has always sat in rare mechanical territory, even by high-complication standards.

The new platinum edition sharpens that position with a rhodium-coloured dial, darker grey registers and a 100-piece run that puts the focus back on one of Glashütte’s most technically expressive chronographs.

It’s a watch built around a deceptively simple idea taken to an extreme: a split-seconds chronograph that can compare elapsed seconds, minutes and hours for up to 12 hours.

At a glance

A platinum case for Lange’s most complex chronograph language

The new Triple Split is housed in a 43.2mm case made from 950 platinum, measuring 15.6mm thick.

Those proportions are substantial, but they’re also part of the watch’s identity, with the architecture dictated by the movement’s layered mechanics and the need to keep a dense display readable.

The case mixes polished and satin-brushed surfaces, giving the watch the familiar Lange balance of formal restraint and machine-like precision.

Three pushers manage the chronograph functions.

The 2 o’clock pusher starts and stops the chronograph, the 4 o’clock pusher controls the flyback, and the 10 o’clock pusher operates the rattrapante system.

The dial is made from 925 silver with a rhodium-coloured main surface and darker grey subdials, a combination that gives the watch a cooler, more technical character than the earlier precious-metal executions.

The layout remains disciplined despite the amount of information on display.

The elapsed-hours register sits at 12 o’clock, the jumping elapsed-minutes counter is placed at 4 o’clock, and the subsidiary seconds appear at 8 o’clock.

At 6 o’clock, Lange’s Ab/Auf power-reserve indication anchors the lower half of the dial.

Blued steel rattrapante hands introduce a clear functional distinction, while red accents appear on the hour and minute counters and the power-reserve display.

The rhodiumed hour and minute hands, along with the markers at 3, 6, 9 and 12 o’clock, are treated with luminous material.

A tachymeter scale sits on the flange, adding another layer of chronograph utility without overwhelming the main dial surface.

How the triple rattrapante changes the chronograph

A standard split-seconds chronograph lets the wearer stop one central seconds hand to read an intermediate time while the main chronograph hand continues running.

The Triple Split extends that same principle across seconds, minutes and hours.

When the chronograph is activated, the three blued rattrapante hands travel in step with their corresponding chronograph hands.

Pressing the 10 o’clock pusher stops all three rattrapante hands at once, allowing the wearer to read a comparative time up to 12 hours while the chronograph itself keeps measuring.

Press the pusher again and the stopped hands catch up with the running chronograph hands before continuing their measurement.

That ability gives the watch a practical mechanical distinction rather than a merely theoretical one.

It can compare long-duration events in a way that most rattrapante chronographs simply can’t, making it one of the clearest demonstrations of Lange’s taste for complex but legible engineering.

Calibre L132.1 through the sapphire back

The watch is powered by the manually wound manufacture calibre L132.1, a 567-component movement developed for the Triple Split.

It runs at 21,600 vibrations per hour and provides a 55-hour power reserve.

The calibre uses 46 jewels, two column wheels and a deeply layered switching architecture for the flyback chronograph and triple rattrapante functions.

Viewed through the sapphire caseback, the movement has the depth and mechanical theatre that Lange collectors expect from the brand’s high complications.

Untreated German silver plates and bridges are decorated with Glashütte ribbing, while levers and springs are straight-grained and bevelled.

Five screwed gold chatons and a hand-engraved balance cock complete the traditional Saxon finishing vocabulary.

A 100-piece edition with a formal presentation

The platinum Triple Split is fitted to a dark-brown hand-stitched alligator leather strap with grey stitching.

It is secured by a quick-release deployant buckle in platinum.

Production is limited to 100 numbered pieces, each with an engraved edition number.

The watch will be presented during the Concours of Elegance at Hampton Court Palace in early September 2026.

Pricing is listed on request, which is unsurprising for a limited Lange grand complication in platinum.

Details & Specifications

For collectors who value mechanical depth over surface novelty, this platinum Triple Split is a reminder of what Lange does unusually well: turn an extreme chronograph concept into something coherent, wearable and unmistakably Saxon.
