The most impressive novelty from A. Lange & Söhne this year at Watches & Wonders 2025 is the new Minute Repeater Perpetual with a black enamel dial. This horological masterpiece brilliantly marries the acoustic precision of a minute repeater with the mathematical complexity of a perpetual calendar. Either complication standing alone would represent a significant technical achievement; their integration into a single timepiece presents an extraordinary challenge.
