The A. Lange & Söhne Datograph Perpetual Tourbillon lives up to its name. It has a date, a chronograph, a perpetual calendar, and a tourbillon. But it has more: this watch has character. Assigning human traits to a cold machine is a – romantic – fool’s errand, but it’s also irresistible in the presence of a masterpiece. A. Lange & Söhne’s warmest watch is more than a machine with a heartbeat. It has soul.
