This platinum A. Lange & Söhne Datograph Up Down Ref 405.035 is rated 9.9 out of 10. It comes with box and paper dated in November 2015. The Datograph from A. Lange & Sohne is a sacred object amongst watch collectors. It is, according to some, one of, if not the chronograph of this generation. This is the newer model, on which the Roman numerals have made place for baton hour markers, the case has been enlarged from 39mm to 41mm, and it now offers 60 hours of autonomy when fully wound (that’s 24 hours more than on the previous generation.) Although the visual changes might seem almost insignificant, the new generation Datograph definitely has a more modern look. The Datograph offers an outsized date and a fly-back chronograph.
