A. Lange & Söhne Grand Lange 1 115.031

A. Lange & Söhne Grand Lange 1 (Ref. 115.031) is a prestigious 42mm timepiece crafted in 18k pink gold. This model is distinguished by its striking black and anthracite solid-silver dial, featuring an asymmetrical layout that follows the "golden ratio" for aesthetic balance. The dial includes an off-center hour and minute circle with pink gold Roman numerals, a subsidiary seconds sub-dial, a signature oversized "big date" display at 2 o’clock, and a power reserve indicator. Inside, the watch is powered by the manual-wind Calibre L901.2, a movement comprising 365 parts and 53 jewels that offers a substantial 72-hour power reserve.
