A Lange Sohne Lange 1 Perpetual Calendar Platinum 41.9mm Black Dial 345.036 E - BRAND NEW

The A. Lange & Söhne Lange 1 Perpetual Calendar in platinum, reference 345.036 E, represents the apex of the storied Lange 1 lineage — a family of watches that single-handedly re-established Glashütte as a world watchmaking capital when A. Lange & Söhne relaunched in 1994. The original Lange 1 introduced an asymmetric dial architecture that broke every convention of the era, and the Perpetual Calendar variant layers one of horology's most demanding complications onto that iconic canvas without sacrificing the design's characteristic clarity and balance.

At 41.9mm, the platinum case commands genuine wrist presence while remaining elegantly proportioned for formal or business wear. Platinum is the most prestigious of all watch case metals — denser than gold, naturally white without requiring rhodium plating, and extraordinarily resistant to wear and tarnish. The weight of a platinum Lange 1 on the wrist is a constant, tactile reminder of the exceptional materials at work, and the cool, muted luster of the metal perfectly frames the sophistication of the movement architecture beneath.

The black dial of reference 345.036 E — finished with a combination of index and Roman numeral hour markers — provides dramatic contrast and exceptional legibility. A. Lange & Söhne's signature outsize date, displayed in the oversized double aperture that defines every Lange 1, anchors the asymmetric layout alongside the perpetual calendar subdials. The perpetual calendar mechanism tracks the day, date, month, and leap year, requiring no manual correction until the year 2100, and the dial integrates these subdials with the Lange 1's characteristic hierarchical legibility so that every complication reads instantly.

The movement powering this reference is a finely finished German mechanical caliber that exemplifies A. Lange & Söhne's relentless pursuit of in-house excellence. Every movement produced in Glashütte is assembled twice — once to verify all functions, then disassembled, individually decorated, and reassembled to the finished standard — a practice that guarantees both performance and the extraordinary visual quality visible through the display caseback. The three-quarter plate in German silver, hand-engraved balance cock, and blued steel screws are hallmarks of authentic Lange craftsmanship.

The leather strap completes the ensemble with quiet refinement, pairing naturally with the cool tone of the platinum case and the depth of the black dial. This combination makes the Lange 1 Perpetual Calendar 345.036 E equally at home at a formal occasion or a serious collector's winding box. Given the scarcity of platinum references and the perpetual calendar complication together in brand-new condition, this watch represents a genuinely rare opportunity in the secondary and new-supply market.
