A. Lange & Söhne 1815 “200th Anniversary F. A. Lange” in honey gold

Prestigious German watch manufacture A. Lange & Söhne pays tribute to Ferdinand Adolph Lange, who was born 200 years ago, with a second exclusive anniversary edition. The limited special 1815 model features a case in honey gold as well as a solid-silver argenté- grainé dial.
In 2015, A. Lange & Söhne is celebrating the 200th birthday of Ferdinand Adolph Lange. In his honour, the commemorative 1815 “200th Anniversary F. A. Lange” edition in platinum with a black dial was launched last February. Now, with the introduction of a second version, A. Lange & Söhne pays tribute to the founder of Saxon precision watchmaking yet again – with another exceptional timepiece. Its characteristic features: a dial with a special surface finish and a case crafted from an innovative gold alloy.
The solid-silver dial of the new 1815 “200th Anniversary F. A. Lange” is endowed with a finely textured argenté- grainé surface. With this artisanal decoration, reminiscent of the silvery dials of historic observation watches and marine chronometers, the Saxon manufactory showcases a rare and traditional finishing technique.
Composed of 188 parts, the manually wound calibre L051.1 has a power reserve of 55hours. In every detail, it represents Saxon watchmaking artistry as taken to a new level of perfection by A. Lange & Söhne. Its key hallmarks include the three-quarter plate made of untreated German silver, the hand-engraved balance cock, the classic screw balance, the precision beat-adjustment system with lateral set screw and whiplash spring, and five gold chatons that are secured with thermally blued steel screws.
The 40-millimetre case in honey gold is engraved with a serial number between 001/200 and 200/200, which identifies each 1815 “200th Anniversary F.A. Lange” as part of a limited edition.
