The A. Lange & Söhne Datograph is one of the icons of modern watchmaking. And it has only been on the market since 1999.
It now offers 60 hours of autonomy when fully wound. This watch has magnificent three-dimensional "landscape” of bridges, levers, cams, jewels and a column-wheel.
The chronograph features a fly-back function, a precisely-jumping minute counter, a quick-set oversized date and two subdials that are very recognizable because of their positioning on the dial. Between these two subdials is a power reserve that indicates how much of the 60 hours of power remains in the single main spring.
The baton hour markers stand out beautifully against the matte black dial, and so does the tachometer scale, printed in white, that surrounds the dial. The two sub dials, displaying the continuous running seconds and the 30-minute chronograph register, are in a matte silver colour. The hands in both sub dials are in heat blued steel; just one of the many beautiful details.
The Datograph’s movement is calibre L951.6 that comprises 451 parts in total. All bridges and the main plate are crafted from untreated German silver, which over time, gets a bit of patina that adds a warm yellowish. The entire movement is lavishly finished by hand. Bridges are angled and the angles are polished, the flat surfaces are adorned with Glashütte striping (the German equivalent of côte de Genève striping) and jewels are set in gold chatons that are fixed by three heat blued screws.
