A. Lange and Sohne 345.036 Lange 1 Perpetual Calendar Platinum Black Dial

Introduced in 2023, the A. Lange and Sohne Lange 1 Perpetual Calendar ref. 345.036E in platinum with a black dial is a striking evolution of the Lange 1 lineage, marrying its iconic asymmetric design with a full perpetual calendar. Housed in a 950 platinum case measuring 41.9 mm in diameter and 12.1 mm thick, this boutique-exclusive “Darth” edition showcases a solid‑silver black dial that elegantly frames the peripheral month ring, oversized date, retrograde weekday, leap‑year indication, and a two‑level moon‑phase with integrated day/night display. Powering the piece is the in‑house automatic calibre L021.3, a beautifully finished movement with a 50‑hour power reserve, 21,600 vph frequency, German silver bridges, hand‑engraved balance cock, and a 21‑carat gold rotor with a 950 platinum centrifugal mass. The instantaneous jumping calendar mechanism, including the peripheral month ring, underscores Lange’s technical mastery, while the platinum case and deep black dial lend a stealthy yet luxurious presence. With its technical sophistication, boutique exclusivity, and refined execution, this Lange 1 Perpetual Calendar is a modern classic for discerning collectors. Like New with A. Lange and Sohne box and papers dated 2024.
