A. Lange and Sohne 310.026 Langematik Perpetual 18K White Gold Black Dial

The A. Lange and Sohne Langematik Perpetual reference 310.026 in 18K white gold with black dial represents a pinnacle of Saxon watchmaking, first introduced in 2014 as the brand’s inaugural automatic perpetual calendar with outsized date. Its compact 38.5 mm diameter and slender 10.2 mm profile house the in‑house calibre L922.1 SAX‑0‑MAT, featuring a 21‑carat gold rotor with platinum centrifugal mass, three‑quarter German silver plate, hand‑engraved balance cock, and the ingenious zero‑reset mechanism for precise time setting. The perpetual calendar is elegantly arranged with day, month, leap‑year, moon‑phase, and a day/night indicator, while the outsized date at 12 o’clock ensures instant legibility. A power reserve of approximately 46 hours and a moon‑phase accuracy that deviates only one day every 122.6 years underscore the technical refinement of this movement. The black solid‑silver dial with rhodiumed gold hands and applied Roman numerals creates a striking contrast that enhances readability and visual depth. Though no longer part of the current collection, this reference remains highly sought after by collectors for its combination of mechanical sophistication, restrained elegance, and historical significance as a milestone in Lange’s perpetual calendar lineage.
