The A. Lange & Söhne Datograph Perpetual is arguably one of the most fascinating chronograph perpetual calendar wristwatches produced by a modern manufacture. With a beautiful combination of traditional watchmaking and fine aesthetics, the Datograph Perpetual displays a well-balanced dial layout on the front, and when flipped to the movement side, it displays its in-house manual movement, expertly finished throughout with Glashütte stripes and signature hand-engraved balance cock. The elegant display includes a 60-second counter and a 30-minute counter, as well as indications for the day of the week, month, leap year, and day/night. Additionally, the chronograph integrates a useful flyback function, which is activated with the top chronograph pusher. This white gold A. Lange & Söhne Datograph Perpetual was the first to bear a German silver dial in this dark grey color, a hint of coolness against the subtle warmth of white gold.
