The A. Lange & Sohne Langematik Perpetual Calendar Ref. 310.025 is a masterclass in Saxon watchmaking a seamless blend of traditional craftsmanship and technical sophistication. Introduced in the early 2000s, the Langematik Perpetual was the first automatic perpetual calendar with an outsize date display, a hallmark of the brand. Housed in a solid platinum case, the watch features a beautifully balanced silver dial that displays day, date, month, leap year, and moon phase with unmistakable Lange clarity. The caliber L922.1 Sax-O-Mat movement powers these complications with a three-quarter plate, hand-engraved balance cock, and zero-reset seconds function a detail that speaks to both mechanical innovation and thoughtful precision. This example is in excellent condition, showing no notable signs of wear. The platinum case retains its crisp edges and original finish, while the silver dial is perfectly clean, displaying the moonphase, calendar indications, and large date window in pristine form. The sapphire crystal is flawless, and the black alligator strap is fitted with the original Lange platinum buckle. The watch is accompanied by its original box and papers, underscoring its completeness and careful preservation. Elegant, technically brilliant, and deeply emblematic of A. Lange & Sohnes modern renaissance, the Ref. 310.025 stands as one of the most refined perpetual calendars of its era a watch that captures both the intellect and artistry of contemporary German horology.
