A. Lange & Söhne once again redefines the boundaries of modern mechanical horology with the debut of the new TRIPLE SPLIT in 950 platinum. Engineered to measure and compare intermediate times up to 12 hours, this flyback split-seconds chronograph —the only one of its kind in watchmaking— debuts a sophisticated colorway featuring a rhodium-dusted dial with contrasting dark gray subdials, strictly limited to 100 pieces worldwide.
Two Additional Dimensions in Short-Time Measurement
Since its groundbreaking launch in 2018, the TRIPLE SPLIT has held an unmatched technical milestone in fine watchmaking: it remains the only mechanical chronograph capable of measuring lap times and comparative intervals up to a full 12-hour limit. Unlike a conventional rattrapante —which is restricted to 60-second intervals— this masterpiece incorporates three pairs of synchronized hands (seconds, minutes, and hours) that allow intermediate time measurement with split-second precision without stopping the main timekeeping run.
Its 950 platinum case measures 43.2 mm in diameter and 15.6 mm in thickness. Set against the rhodium-dusted 925 solid-silver dial are blued steel split-seconds hands, a peripheral tachymeter scale, and the iconic AUF/AB power reserve indicator at 6 o’clock, which tracks the movement’s maximum 55 hours of autonomy.
⚙️ Patented Innovation
The Disengagement Mechanism of Calibre L132.1
To prevent friction losses and amplitude drops when the split-seconds hands are stopped, Lange integrated a patented disengagement mechanism (developed in 2005). This system decouples friction-inducing processes from the central seconds and minute arbors, ensuring consistent rate stability across the regulating system.
In-House Calibre L132.1: Architectural Depth and Finely Finished Components
At the core of this timepiece is the In-house Calibre L132.1, a mechanical marvel composed of 567 individual hand-finished parts. Through the sapphire crystal caseback, the movement reveals extraordinary visual depth: untreated German silver plates finished with Glashütte ribbing, five gold chatons secured by thermally blued screws, and a hand-engraved balance cock with a whiplash precision index assembly.
Pros and Cons
Pros:
- The world’s only mechanical chronograph capable of triple split-seconds timing up to 12 hours.
- 567-part Calibre L132.1 featuring a patented disengagement system to optimize power distribution.
- Striking visual presence with a 950 platinum case paired with a contrasting rhodium and dark gray dial.
Cons:
- Case thickness of 15.6 mm resulting from the complex multi-layer split-seconds mechanism.
- Strictly limited production run of only 100 numbered pieces globally.
