A. Lange & Sohne Datograph Perpetual Manual Platinum (410.025)

The A. Lange & Sohne Datograph Perpetual (ref. 410.025) features a mechanical manual winding movement with a 36-hour power reserve; chronograph with flyback and precisely jumping minute counter; rhodiumed silver dial with Lange's patented large date display; moon-phase display; sapphire-crystal, transparent case back; and 41mm, platinum case on a black crocodile strap with a platinum deployant clasp.

The A. Lange & Sohne Datograph Perpetual is an extremely interesting horological masterpiece in that it was designed to be able to measure both extraordinarily short, as well as extremely lengthy periods of time. The Datograph Perpetual combines two classic complications- the chronograph (to measure short time periods down to the millisecond) and the perpetual calendar (to keep time through the years).
