In 1994, A. Lange & Söhne signalled its return to the forefront of the watchmaking stage by presenting four watches including the surprising Lange 1 model characterised by offset displays and an innovative large date. Having become the brand’s flagship model, it now incorporates a perpetual calendar while losing nothing of its personality. The date retains its large aperture, while the day of the week is shown by a retrograding hand and the month by a tiny arrow pointing to a peripheral rotating disc at 6 o’clock, topped by the leap-year indication. Meanwhile, the moon phase is integrated within the small seconds subdial and the overall aesthetic result is harmonious, extremely understated and yet nonetheless highly readable. The movement with its patented construction also comprises a tourbillon with stop seconds device that is visible through the caseback. The ingenious Lange 1 Tourbillon Perpetual Calendar, the most complicated Lange 1 watch to date, is available in an unlimited edition with a rose gold case, and in a 100-piece platinum limited edition.
