- With the renaissance of A. Lange & Söhne in 1990, the Saxon manufacture unveiled the Lange 1 timepiece in 1994. This iconoclast featured an asymmetric dial of peerless legibility, with an oversized date display at one o’clock and a retrograde power reserve indication spanning two to four o’clock. To herald the new millennium, A. Lange & Söhne released a series of Lange 1 models integrating various complications—culminating in the Lange 1 Tourbillon, the ne plus ultra of the Lange 1 family.

- Issued as a limited edition of 250 examples in 18K pink gold and 150 in platinum, the Lange 1 Tourbillon was crafted for a fleeting three years, discontinued in 2003. Ensconced within a traditional 38.5mm round case, its sapphire crystal caseback reveals the three-quarter plate of German silver, hand-engraved with the A. Lange & Söhne hallmark, and a balance cock lavishly engraved à la main.

- At five o’clock resides a tourbillon of breathtaking virtuosity, composed of 72 individual parts. The cage makes one full rotation every minute, improving precision by averaging out the slightest errors each part can have in different position. The tourbillon was a 19th-century innovation that continues to mesmerize; in the Lange 1 Tourbillon, it captivates anew.

- The present example, No. 61 of the pink gold edition, dates to circa 2000. Preserved in excellent condition with minimal signs of wear from the past, this early specimen of the reference represents a rare opportunity to acquire an icon of German watchmaking mastery and a pivotal moment in A. Lange & Söhne's renaissance.
