The sporty new Datograph Up/Down Lumen from A. Lange & Söhne, Germany’s most prestigious watchmaker, is getting glowing reviews—literally. Thanks to a semi-transparent dial bathed in a luminous display that causes it to glow with a green hue in darkness, the wristwatch is a reliable timekeeper at all hours of the day and night.
The fourth model in the Lumen series, which kicked off in 2010, the Up/Down Datograph is sought after by collectors for its combination of good looks and powerful mechanics.
Blessed with a flyback function, a precisely jumping minute counter and a power-reserve indicator, the timepiece is fronted by a dense but elegantly designed dial that bears the Lange signature: an outsize date display in the framed double aperture, noticeably aglow in green.
The coloration is achieved by a special coating on the semitransparent sapphire crystal dial that filters out most of the visible light, leaving only that part of the UV spectrum which is needed to charge the luminous pigments with light energy.
Befitting its prestige status, the watch comes in a 41 mm platinum case on a black alligator strap with a platinum pin buckle and is available in a limited edition of 200 watches. Glow for it!
