In 2014, A. Lange & Söhne introduced the 1815 Tourbillon, an exceptional execution of classic German engineering presented in a platinum case. Visible through the sapphire crystal caseback, the movement displays signature Lange finishing, including Glashütte stripes, gold chatons secured by blued screws, red rubies and a hand-engraved balance cock. In homage to historic Saxon watchmaking tradition, the tourbillon features a diamond endstone. The untreated German silver mainplate has aged gracefully to a warm, golden-yellow hue, lending the watch a distinct and charming character.
With the 1815 Tourbillon, Lange elevated the complication’s foundational purpose—chronometric precision—by integrating a hacking mechanism paired with a zero-reset function. Pulling the crown stops the tourbillon cage and instantly snaps the small seconds hand to zero, allowing for exact time setting down to the second.
To the best of our knowledge, only four examples (numbers 32, 52, 67, and 92) of reference 730.025 have ever appeared at public auction. Numbered 8 from the limited edition, the present lot is potentially the earliest example to surface on the market. Offered fresh to the market in exceptionally well-preserved condition with minimal wear, it is complete with its full suite of original accessories, including an additional platinum deployant clasp and a matching presentation box stamped with the limited edition number 8.
A. Lange & Söhne
German | 1845Originally founded in 1845 by Ferdinand Adolph Lange in Glashütte, Dresden, Germany, the firm established an entire watchmaking culture and industry in Glashütte. The brand quickly became Germany's finest watchmaker, first creating dependable, easy-to-repair watches before going on to produce some of the world's finest complicated pocket watches, including Grande Sonnerie watches, tourbillon watches and Grande Complications.
On the final day of World War II, their factories were destroyed by Russian bombers, and in 1948 the brand was confiscated by the Soviet Union. Following the fall of the Berlin Wall in 1990, Ferdinand's great grandson Walter Lange re-established the brand with the objective to once again produce top-quality luxury watches. Now part of the Richemont Group, its original vintage and modern creations are highly coveted by collectors. Key models from the modern era include the Lange 1, Pour Le Mérite Tourbillon and the Zeitwerk.
