A. Lange & Söhne 310.025 Langematik Perpetual Platinum Silver Dial WELLENDORFF

Introduced in 2001, the A. Lange and Sohne Langematik Perpetual ref. 310.025 in platinum embodies the brand’s mastery of understated complexity. Its 38.5 mm platinum case, just 10.2 mm thick, houses the automatic caliber L922.1 with a micro‑rotor, delivering a 46‑hour power reserve and the zero‑reset seconds function for precision time setting. The solid silver dial, adorned with applied Roman numerals, presents a perpetual calendar with moon‑phase, day, date, month, leap‑year, and 24‑hour indications in a layout that balances clarity and elegance. Though not a limited edition, this platinum version remains rare, especially when paired with a Wellendorff platinum bracelet, a combination seldom seen and highly prized by collectors. The movement’s finishing, the Sax‑O‑Mat architecture, and the perpetual calendar’s longevity—requiring no adjustment until 2100—underscore the technical and horological significance of this piece. It stands as a refined testament to Lange’s tradition of precision, discreet luxury, and mechanical sophistication. Like New with A. Lange and Sohne box and papers dated 2009.
