A. Lange & Söhne Zeitwerk 140.029

A. Lange & Söhne Zeitwerk 140.029 is a bold reinterpretation of timekeeping, combining avant-garde digital display with traditional Saxon craftsmanship. Crafted in 18k white gold, this 41.9mm timepiece features a striking black dial made of solid silver, punctuated by two oversized windows that display jumping hours and minutes—an ingenious mechanical execution that ensures instantaneous and precise legibility. At the top of the dial, a power reserve indicator marked “AUF” (wound) and “AB” (run down) adds functional depth, while a small seconds subdial anchors the composition at 6 o’clock. Beneath the surface lies the manually wound caliber L043.1, equipped with a constant-force escapement that regulates energy delivery to the jumping numerals, ensuring consistent accuracy and performance. With a 36-hour power reserve and a sapphire crystal case back revealing the movement’s intricate architecture.
