SIHH: The Lange 1815 Moonphase Returns

Lange  1815 Moonphase FA Lange Edition

2010 is Lange’s 165th anniversary, and to mark the occasion they are creating new versions of 3 well-known models in a new metal called honey gold, which is not only a unique color, but it is also nearly twice as hard as regular gold. Together, the new models are known as the F. A. Lange Homage Collection. Among the new releases is an 1815 Moonphase.

The original 1815 Moonphase limited edition from 1999 was a hit with collectors, selling at auction for nearly triple the original selling price. This newest version will certainly carry on that tradition. Limited to 265 pieces and with a European MSRP of 18,500 euro, the new 1815 Moonphase case and balance cock are formed from Lange’s new and proprietary honey gold. Like the other pieces in the Homage to F.A. Lange Collection, the 1815 Moonphase also features three-quarter plate with hand-engraved traditional decoration. Of course the moon phase display is accurate to an amazing 1 day in 1058 years.
