A. Lange & Söhne launches limited 1815 Up/Down models

A. Lange & Söhne has released new limited edition versions of its 1815 Up/Down model. These new references feature a reduced case size of 37.5mm, positioned between the original 35.9mm debut size and the current 39mm standard.

The watches are available in either 18k white gold or 18k pink gold and maintain a slim profile with a case height of 8.7mm. The dials feature a desaturated blue color with silver subdials for the power reserve and running seconds, a design inspired by late 19th-century German pocket watches.

Both versions are powered by the manually wound L051.2 caliber, which is visible through an exhibition caseback. The movement is constructed from German silver and features high-end finishing, including gold chatons and engraved components.
