The watch’s manufacture movement, manual-wind Caliber L051.1, bears all the hallmarks of the classical Glashütte horological style, including the three-quarter plate made of untreated German silver, a hand-engraved balance cock, classical screw balance, whiplash spring, gold chatons to secure the bearing jewels, and thermally blued screws. The three-quarter plate, in particular, is a living symbol of F.A. Lange’s contributions to German watchmaking, invented in its current form in 1864 for the purpose of better stabilizing the overall movement.
The A. Lange & Sohne 1815 “200th Anniversary F.A. Lange” is delivered on a had-stitched black alligator leather strap with a platinum pronged buckle. Each watch bears an engraved series number (001 through 200) on the caseback. It will be priced at $33,500. Scroll down for more specs on the watch.
