Lange 1 Moonphase Manual Yellow Gold (109.021)

The A. Lange & Sohne Lange 1 Moonphase watch (ref. 109.021) features a mechanical manual winding movement with a 72-hour power reserve; champagne dial with Lange's patented large date display; sapphire-crystal, transparent case back; and 38.5mm, 18k yellow gold case on a hand-stitched, brown crocodile strap with an 18k yellow gold ardillon buckle.

The A. Lange & Sohne Lange 1 Moonphase presents a new highlight in precision watchmaking in a number of respects. Foremost, the Lange 1's moon imitates cosmic reality very faithfully in that it moves continuously, as opposed to in leaps and bounds, as is the case with most mechanical moonphase watches. Moreover, the Lange 1 Moonphase's mechanism is so accurate that the accrued error is less than one day per 122.6 years of lunar orbit.
