Fans of a moon-phase complication will be fully rewarded by the Grand Lange 1 Moon Phase. On the silver dial, the sky glows a deep blue, with the moon and stars rendered in gold. This precious metal is echoed in the applied numerals and indices. With uninterrupted running of the hand-wound movement, a correction of the moon-phase display by one day is required only after 122.6 years. The 18-karat rose-gold case measures 41 × 9.5 millimeters. The up/down power-reserve indicator shows how many of the 72 hours of power reserve have already elapsed.
