Since its debut in 1994 after A. Lange & Söhne's reestablishment, the Lange 1 has embodied the maison's quest for horological perfection. In the decades since, few timepieces have garnered more acclaim than this foundational icon. The original four Lange 1 models encapsulated a courageous new beginning, while upholding Lange's distinguished German watchmaking heritage. Its bold asymmetric dial layout with outsized date and off-center time display marked a contemporary stylistic code that later influenced watch design industry-wide.

In 2020, Lange released two new Lange 1 Perpetual Calendar references, including this exclusive limited edition of 150 pieces in white gold with a sublime 18K pink gold dial, or as some may call it the highly desirable “Salmon” dial. Rather than utilizing an existing movement minus the tourbillon, the Lange 1 Perpetual Calendar is powered by the new cal. L021.3. The dial exquisitely showcases the perpetual calendar, with the month indicated via a ring along the periphery and read by a gold pointer at 6 o'clock. Though similar to its predecessor, refinements include integrating the day/night indicator into the moonphase and redesigning the time subdial to match the Lange 1 Moon Phase.

Numbered 125 of 150 and accompanied by its full set of accessories, the present example remains within its original guarantee period. Offered in virtually unworn condition, collectors are treated to Lange's exemplary perpetual calendar watchmaking artistry with this exclusive timepiece.
