A. LANGE & SÖHNE - LANGE 1 - Reference 101.021 - 18K Yellow Gold -  Lange Service 2026 - Excellent

The A. Lange & Söhne Lange 1 is not merely a timepiece—it is a cornerstone of modern haute horlogerie and a symbol of German watchmaking’s triumphant return to the world stage. Offered here is a particularly elegant example: Reference 101.021 in 18k yellow gold, featuring the highly sought-after light champagne dial, paired with a refined brown crocodile leather strap and the original 18k yellow gold pin buckle.

The dial layout of the Lange 1 is instantly recognizable and entirely unique. Its asymmetric design, governed by the golden ratio, achieves a perfect visual balance while displaying hours, minutes, small seconds, power reserve indicator, and the iconic outsize date—a signature complication inspired by the historic five-minute clock of the Semper Opera House in Dresden. The warm champagne tone of this dial harmonizes beautifully with the yellow gold case, giving the watch a timeless, understated elegance that works effortlessly in both formal and casual settings.

At the heart of this timepiece beats the renowned Lange manufacture caliber L901.0, a manually wound movement that exemplifies the brand’s uncompromising approach to craftsmanship. Comprising over 350 individual components, the movement features untreated German silver three-quarter plates, gold chatons secured by thermally blued screws, and a hand-engraved balance cock—each one unique to the watchmaker who crafted it. The caliber offers a power reserve of approximately 72 hours and incorporates a precise stop-seconds mechanism for accurate time setting. Its architecture and finishing are widely regarded as among the finest in the world.

All of this mechanical artistry can be admired through the sapphire crystal caseback, which reveals the movement in full detail. The transparent back transforms the watch into a visual experience, allowing the wearer to appreciate the depth, texture, and hand-finishing techniques that define A. Lange & Söhne. From the Glashütte ribbing to the polished bevels and intricate engraving, every element underscores the maison’s dedication to traditional watchmaking at the highest level.

This example is presented in excellent condition and has just undergone a full factory service by A. Lange & Söhne in March 2026. It comes complete with its official service box and service report, ensuring both authenticity and peace of mind for the next owner. The movement performs to the highest standards, as expected from one of the finest manufactures in the world.

First introduced in 1994, the Lange 1 marked the rebirth of A. Lange & Söhne after the reunification of Germany. Alongside three other inaugural models, it re-established the brand as a leader in high-end watchmaking. The Lange 1 quickly became the flagship model thanks to its bold design, technical excellence, and unmistakable identity.

"A watch of enduring value, heritage, and unmistakable character—this is A. Lange & Söhne at its very best."
