A. Lange and Sohne 310.025E Langematik Perpetual Platinum Silver Dial

The A. Lange and Sohne Langematik Perpetual ref. 310.025E, first introduced in 2001, stands as the marque’s pioneering automatic perpetual calendar wristwatch, marrying technical innovation with classical Saxon elegance. Housed in a 950 platinum case measuring 38.5 mm in diameter and just over 10 mm thick, it features a solid silver dial with applied Roman numerals and the signature Lange outsized date at 12 o’clock. The in‑house calibre L922.1 Sax‑O‑Mat movement, complete with a 21 k gold micro‑rotor and zero‑reset seconds mechanism, delivers a 46‑hour power reserve and flawless perpetual calendar functionality, including day, month, leap‑year, moon‑phase, and day/night indications. The sapphire display back reveals the hand‑engraved balance cock and Glashütte three‑quarter plate, underscoring the brand’s artisanal pedigree. As the longest‑produced Langematik Perpetual reference, discontinued in 2017, this platinum execution remains a highly coveted collector’s piece for its technical sophistication and restrained refinement.
