About the Movement

The L121.1 is the current-generation Lange 1 movement, introduced in 2015 as a comprehensive refinement of the original L901.0. It retains the twin mainspring barrel that provides 72 hours of power reserve — allowing the watch to run through a weekend without winding — and adds a freely oscillating balance spring manufactured entirely in-house, with a patent-pending attachment system. The movement beats at 21,600 semi-oscillations per hour and features a precision beat-adjustment mechanism accessible through the caseback. The hand-engraved balance cock, a tradition maintained on every Lange movement, is individually decorated by a single craftsman and never mass-produced.
About the Family
The Lange 1 was introduced on October 24, 1994 — the day A. Lange & Söhne announced its return to watchmaking after more than four decades of silence. It was one of four watches unveiled that day and immediately established the brand’s identity: asymmetric dial layout, outsize date, subsidiary seconds, and a level of hand-finishing that had not been seen in German watchmaking for a generation. The asymmetry was deliberate — a rejection of the convention that a watch dial must be symmetrical — and it created a composition that rewards extended study. Every subsequent generation of the Lange 1 has refined the movement and dial without changing the essential character of the reference.
About this reference
The Lange 1 is the watch that announced A. Lange & Söhne’s return to watchmaking in 1994 and remains the brand’s most iconic reference. Its asymmetric dial — a deliberate break from convention — houses an outsize date at 1 o’clock, a power reserve indicator, and a subsidiary seconds dial, each element precisely positioned to create a balanced composition out of apparent imbalance. The yellow gold case pairs with a champagne dial and blued steel hands, embodying the warmth and restraint that defines Glashütte’s finest dress watches. The L121.1 calibre, entirely manufactured in-house, features a twin mainspring barrel for 72 hours of power reserve and a hand-engraved balance cock — a tradition maintained on every Lange movement.
