Lange 31 Platinum (130.025)
The A. Lange & Sohne Lange 31 watch (ref. 130.025) features a mechanical manual movement wound with a winding key; rhodiumed silver dial with Lange's patented large date display; power reserve display; small seconds subdial; sapphire-crystal, transparent case back; and 45.9mm, platinum case on a hand-stitched, black crocodile strap with a solid, platinum deployant clasp.
With its unprecedented 31-day power reserve, the Lange 31 again demonstrates A. Lange & Sohne's ability to redefine benchmarks in precision watchmaking. In order to keep the Lange 31 running accurately for such a long period of time, A. Lange & Sohne invented a constant-force escapement that powers the going train with consistent torque delivery.
