A. Lange & Söhne Lange 1 Moon Phase 192.032

About This Watch

The A. Lange & Söhne Lange 1 Moon Phase adds a poetic lunar complication to the iconic asymmetric dial, with the moon phase and day/night indicator occupying the space that small seconds holds in the standard model. The caliber L121.3 drives a moon phase display of exceptional precision: the lunar disc only deviates from the actual lunar cycle by one day every 122.6 years, achieved through a gear train with 2,923 teeth. The moon itself is rendered in solid gold against a deep blue sky dotted with laser-cut stars, each just fractions of a millimeter in diameter. A day/night indicator at 12 o'clock on the subsidiary dial tracks the sun's position, distinguishing AM from PM for quick reference. The champagne dial in 18k rose gold creates a warm, classical presentation. The 38.5mm case maintains the Lange 1's original proportions, keeping the overall character intimate and elegant. The 72-hour power reserve and outsize date carry over unchanged. Through the sapphire caseback, the three-quarter plate movement displays the unmistakable fingerprint of Glashütte craftsmanship.
