The 1815 MOONPHASE epitomises Lange’s unending quest for the ultimate in precision. No effort was spared to calculate an extremely accurate moon-phase train for this watch. Thanks to a suite of wheels with special transmission ratios, its error per lunar month is a nearly infinitesimal 6.61 seconds. It takes 1,058 years for this error to add up to a deviation of one day relative to the actual lunar cycle. Had such a timepiece existed in the year 952 – during the lifetime of Otto I the Great – and had it run without interruption since then, its moon-phase display would have to be corrected for the first time this year.
Among collectors, the 1999 limited edition pieces of the 1815 MOONPHASE in pink gold and platinum with a black dial rank among the most sought-after Lange timepieces. Their hallmark is an artistic rendering of the “Big Dipper”, probably the best-known constellation, on the dial. At watch auctions, well-maintained exemplars of this coveted treasure sometimes fetch more than three times the original price. The value of the 1815 MOONPHASE “Homage to F. A. Lange” could follow a similar trend: its edition is limited to 265 watches world-wide.
