The hand-wound 1815 Moonphase 212.050 arrives in a signature “honey gold” color courtesy of a particularly hard-to-scratch 18-karat gold alloy. Developed by A. Lange & Sohne, the gorgeous alloy sports a Vickers hardness rating between 300 and 320HV (on average, that is twice as high as that of white gold, which is usually considered to be the hardest among “standard” gold alloys.) The new member of the 1815 Collection features a beautifully executed moon-phase complication, which is not only pleasant to look at, but is also so accurate that it takes whole 1058 years for the calendar to miss a day from the lunar month.
