A Lange & Söhne’s 1815 collection is a modern day tribute to founder Ferdinand Adolph Lange who was born in 1815. It honors his exacting standards and precision quality with movements resembling pocket watches made during his time with three-quarter plate movement, blued screws and gold chatons. Lange worked diligently to consistently reproduce movements in a move toward standardization and better timekeeping. In 1879, A. Lange & Söhne was granted patent number 9349 for a device for pocket watches to indicate how much time remained before a watch was fully unwound.

The 1815 Up/Down is reminiscent of chronometers with a power reserve, which were originally featured on chronometers. First released in 1995, the white gold version with blue dial like the present watch is an elegant and classic timepiece. The clean dial with the power reserve and subsidiary seconds at the 8 and 4 positions respectively is clear and easy to read. The watch has a refined style that is quintessential A. Lange & Söhne and wears comfortably on the wrist. In excellent overall condition this is a refined watch that meets the standards of the most discriminating collector.
