First launched in 1999, A. Lange & Söhne’s Datograph is widely regarded as one of the finest crafted and most beautiful chronograph wristwatches produced by a modern manufacture. The reference 403.035 in a platinum 39mm diameter case had perfect harmony with black dial, Roman numerals, and sunken subsidiary dials. A. Lange & Söhne evolved the model, and in 2012 introduced the Datograph Up/Down reference 405.035 with a larger 41mm case diameter case featuring the caliber L951.6 with 60 hour power reserve and up/down indicator prominent on the dial.
The Datograph Up/Down “Lumen” was launched in 2018 as a limited edition series of 200 pieces. With a complex construction of the main dial in tinted sapphire crystal, the translucency allows the main plate below to be exhibited, proudly displaying its precise perlage finish to the wearer. Although many may think that the implementation of the tinted sapphire was purely for aesthetics, it serves an important purpose. The tinted sapphire dial allows the luminous material to absorb UV rays from daylight to be luminous at night. This feature applies to all luminous components on the dial including the tachymeter scale, subsidiary dials, date, and power reserve indicator.
The present example, numbered 139, is offered by the original owner in excellent condition and complete with its original accessories.
A. Lange & Söhne
German | 1845Originally founded in 1845 by Ferdinand Adolph Lange in Glashütte, Dresden, Germany, the firm established an entire watchmaking culture and industry in Glashütte. The brand quickly became Germany's finest watchmaker, first creating dependable, easy-to-repair watches before going on to produce some of the world's finest complicated pocket watches, including Grande Sonnerie watches, tourbillon watches and Grande Complications.
On the final day of World War II, their factories were destroyed by Russian bombers, and in 1948 the brand was confiscated by the Soviet Union. Following the fall of the Berlin Wall in 1990, Ferdinand's great grandson Walter Lange re-established the brand with the objective to once again produce top-quality luxury watches. Now part of the Richemont Group, its original vintage and modern creations are highly coveted by collectors. Key models from the modern era include the Lange 1, Pour Le Mérite Tourbillon and the Zeitwerk.
