Lange & Sohne 1815 Moonphase Homage to F.A. Lange 212050. This extremely rare and complicated watch is only 9.5mm thick. The dial is solid silver with a fine sunburst guilloche texture in the center, with black Arabic numerals and blued hands that compliment the metallic, indigo moonphase subdial with silver stars, located at 8 o'clock. A small seconds indicator is located at 4 o'clock. The caliber L943.2 manual winding movement has 26 jewels, 220 parts, and oscillates at 21,600 vibrations per hour. The Balance Cock is made of the same 18K honey gold as the case and has intricate hand engraving. The caseback is a transparent sapphire crystal for viewing the mechanism and there is a 45-hour power reserve, water resistant to 30m. The crocodile leather strap has an 18K honey gold tang buckle, and the case, dial, and movement are signed.

Lange & Sohne is one of only a small handful of watch companies in the world are technologically advanced and experienced enough to produce their own balance springs, which is one of the most difficult processes in watchmaking. The precision is breathtaking, for the mechanical forming and the thermal treatment, with springs being rolled to an accuracy of 100 nanometers, or the diameter of 1/100 of a human hair.

The moon-phase complication on this watch is rather incredible all on its own. The indication only needs to be adjusted by one day every 1058 years as long as the power isn't interrupted and the watch remains set to the correct time. The Lange & Sohne engineers invented a moonphase train that supersedes the traditional approximation of a 29.5-day lunar month, using a far more accurate, synodic month of 29 days, 12 hours, 44 minutes, and 3 seconds.

The case material for this watch and only two other models is made of a special gold alloy developed exclusively for Lange called 18K "Honey Gold. It's a subtle tone between yellow and white gold, but with a hardness on the Vickers scale of over 300, making it twice as durable and scratch resistant as other gold alloys. This is a superb timepiece in every way. It exists in a limited edition of only 265 examples. Walter Lange introduced this watch in 2010 in honor of his great grandfather, Ferdinand Adolph Lange, who founded the company in 1845. 2010 marked the 165th anniversary of the company; the homage year of 1815 was the year of Adolph Lange's birth.
