Since its launch in 2012, the Datograph is one of the favorite timepieces among collectors and fans of the Saxony-based brand. First of all, for its technical qualities, including the flyback function serving to perform several successive timing operations simply by pressing the pusher ; as well as its jumping chronograph minutes advancing in one-notch increments as soon as the central hand passes the 60th second, a token of great precision. Other notable and much sought-after features include its large date and its power-reserve indicator (ab/auf – up/down). Finally, these indications are beautifully arranged on an extremely legible dial, a style signature of A. Lange & Söhne. The new “Lumen” version now brings the Datograph another type of clarity radiating a subtly enigmatic aura. While the three large hands bear a traditional luminescent coating, the halo of green light suffusing the counters, the external dial ring, the tip of the power-reserve pointer, and above all the large date, stems from “Lumen” technology. A semi-transparent treated sapphire dial filters the light, while allowing through the ultra-violet rays required to recharge the luminous pigments with phosphorescent energy during the daytime hours. The watch thus glows with a diffuse light in the dark, almost resembling that of a screen. Another of the sapphire dial’s assets lies in its manner of revealing the beautiful circular-grained mainplate and the date disks.
