A. Lange & Söhne Double Split Chronograph Ref. 404.035 – 950 Platinum – Box & Papers –  2005 – One of the Most Important Chronographs Ever Made

We are delighted to present this extraordinary A. Lange & Söhne Double Split Chronograph Ref. 404.035 in 950 platinum, offered as a set including the original presentation box, outer box, cardboard sleeve, leather holder for the instruction manua and the “Book for the Watch” called warranty booklet. Originally retailed in Italy in 2005, this remarkable timepiece represents one of the most significant milestones in modern haute horlogerie.

Introduced in 2004, the Double Split was nothing short of a revolution in mechanical chronograph construction. While traditional rattrapante chronographs allow the measurement of intermediate times for up to 60 seconds, A. Lange & Söhne elevated the concept to an entirely new level by inventing the world's first double rattrapante wristwatch. The Double Split not only features two split-seconds hands but also two split-minute counters, extending the timing of comparative and intermediate events from one minute to an unprecedented thirty minutes.

This groundbreaking achievement remains one of the most sophisticated and intellectually impressive chronograph complications ever serially produced. Even today, more than two decades after its introduction, the Double Split is regarded by collectors and watchmakers alike as one of the greatest technical accomplishments in modern watchmaking.

The imposing 43.2 mm platinum case perfectly complements the complexity housed within. The beautifully balanced dial combines exceptional legibility with unmistakable Lange aesthetics, featuring the signature outsize date, flyback chronograph display, and the unique split-minute indication that immediately distinguishes the Double Split from any other chronograph ever created.

Powering the watch is the magnificent manually wound Lange Manufacture Calibre L001.1, a movement that is widely considered one of the finest chronograph calibres ever constructed. Comprising over 460 individual components, the movement is visible through the sapphire crystal caseback and offers an almost endless level of visual fascination.

The true beauty of the L001.1 reveals itself under magnification. Viewed through a loupe, one can spend hours discovering new details: the hand-engraved balance cock, polished chronograph components, mirror-finished steel levers, gold chatons secured by blued screws, untreated German silver bridges, and the breathtaking three-dimensional architecture of the split-seconds and split-minute mechanism. Every angle, every bevel, every surface demonstrates the uncompromising pursuit of perfection for which A. Lange & Söhne is renowned.

Few watches offer such a rewarding ownership experience. The Double Split is not merely a chronograph—it is a mechanical masterpiece that invites continual exploration and appreciation, revealing new layers of craftsmanship each time the movement is examined.

Today, the Double Split stands among the most collectible creations of the modern Lange era. Produced in very limited numbers and representing a landmark innovation that has never lost its relevance, it occupies a special place within the history of high-end watchmaking.
