A. Lange & Söhne, renowned for its meticulous German watchmaking, is set to captivate enthusiasts with a dazzling new addition to its esteemed Lumen series. The new Lange 1 Tourbillon Perpetual Calendar Lumen, slated for release at Watches and Wonders 2026, promises an extraordinary blend of complex horology and innovative luminescence. This exclusive timepiece redefines legibility in low-light environments, showcasing the brand's commitment to both tradition and avant-garde design. With only a limited number available, this watch is poised to become a prized possession for a select few discerning collectors.

This remarkable creation builds upon the already impressive foundation of the standard Lange 1 Tourbillon Perpetual Calendar. It seamlessly integrates a perpetual calendar, a tourbillon, and a luminous display into a cohesive and visually striking design. The use of a smoked sapphire crystal dial allows ambient light to energize the generously applied luminous elements, ensuring that every detail, from the hands and hour markers to the intricate calendar functions, glows brilliantly after dark. The sophisticated Calibre L225.1 movement, a testament to German engineering, powers this horological marvel, offering precision and a substantial power reserve.

Illuminating Horological Excellence

The A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar Lumen stands as a testament to the brand's innovative spirit, offering a sophisticated blend of high-complication watchmaking and striking aesthetic appeal. This new release, part of the coveted Lumen series, transforms the classic Lange 1 design with a fully luminous display, ensuring readability and visual drama in all lighting conditions. The watch maintains the iconic offset time display and large date aperture while integrating a perpetual calendar with a peripheral month ring and a retrograde day indicator. The ingenious inclusion of a day/night display within the moon phase subdial adds another layer of functionality, with its rotating disc revealing stars or light against a luminous backdrop, all powered by the meticulously refined Calibre L225.1.

The creation of the Lumen model necessitated a meticulous re-engineering of the existing 685-component movement, culminating in the advanced Calibre L225.1. This movement vibrates at 21,600 semi-oscillations per hour and features 74 jewels, along with a stop-seconds mechanism, which is a rarity in tourbillon timepieces. The watch's automatic winding is facilitated by a white-gold rotor with a platinum counterweight, providing a generous power reserve of up to 50 hours. The perpetual calendar is engineered for remarkable accuracy, requiring no manual correction until March 1, 2100. Furthermore, the movement's rear side reveals exquisite craftsmanship, with the tourbillon and intermediate-wheel cocks adorned with delicate star and shooting star motifs, adding a whimsical yet refined touch to this high-precision instrument.

The Luminous Dial and Exclusive Craftsmanship

The most distinctive feature of the Lange 1 Tourbillon Perpetual Calendar Lumen is its innovative luminous dial, achieved through the application of a smoked sapphire crystal. This translucent dial acts as a window to the movement beneath, allowing collectors an unprecedented view of the intricate mechanical dance that powers the watch. Beyond mere aesthetics, this design ensures that all indications, including the date, leap-year disc, moon phase, month, and day, are coated with luminous paint, glowing brightly in the dark. This transformation elevates the watch from a mere time-telling device to a nocturnal spectacle, where every complication remains perfectly visible, embodying a harmonious blend of technical prowess and artistic expression.

Encased in a robust 41.9mm platinum body, the watch boasts a substantial presence on the wrist, complemented by a luxurious black alligator strap. While the tourbillon, a hallmark of high-end horology, is subtly positioned on the movement's reverse side, it offers an unexpected delight upon inspection, revealing the depth of Lange's artisanal skill. This limited edition of only 50 pieces underscores its exclusivity and desirability among collectors. The watch, reference 720.035FE, is priced at €550,000, reflecting its exceptional craftsmanship, complex mechanics, and innovative luminous design. It represents a rare opportunity to own a piece of horological art that shines both day and night, offering a unique and captivating experience for the fortunate few who acquire it.
