The A. Lange & Söhne Datograph needs little presentation. Introduced in 1999 and updated in 2012, it is perhaps the most notable chronographs on the market. The Dato features a flyback chronograph with an exactly bouncing minutes counter, two sub-dials recognizable because of their unusual situating, a fast set larger than average date and a force save indicator. Overall, the architecture and the completing of its development are a feast for the eyes. Any new model in the arrangement always brings interest and fervor among A. Lange & Söhne fans (counting team MONOCHROME… ) So, when we learnt that the Datograph Up/Down was getting the “Lumen” treatment, it naturally caught our attention.
The “Lumen” touch
A. Lange & Söhne watches are particularly German, instantly recognizable for their functional and minimal plan. All that looks balanced, organized and crafted in the admiration of a durable watchmaking tradition. The Lumen arrangement reworks this classic style with a technical, present day curve. With the Lumen arrangement, parts of the dial are made of dark colored hazy sapphire. This treatment sift through the vast majority of the noticeable light yet allows the glowing shades to get charged with light energy. That causes all the displays to sparkle in the light contrasting against the black background.
The A. Lange & Söhne Datograph Lumen is the fourth watch of the Glashütte-based brand to get a Lumen treatment:
- 2010 – Zeitwerk Lumen, platinum – restricted version of 100 watches
- 2013 – Grand Lange 1 Lumen, platinum – restricted version of 200 watches
- 2016 – Grand Lange 1 Moon Phase Lumen – platinum, restricted version of 200 watches
- 2018 – Datograph Lumen Up/Down, platinum – restricted version of 200 watches
The new Datograph Lumen Up/Down
Most of the indications on the Datograph Lumen Up/Down have gotten this shining treatment. The hour and moment hands are loaded up with glowing material and the chronograph clear seconds hand is coated with the same compound. The chronograph counters, the moment scale and tachymeter are radiant as well. Last however not least, the outsize date gleams and is neat in the dark as well! The sapphire glass that covers the dial, with a light-permeable coating, allows the numerals to be charged with enough photonic energy to then radiate it in the dark.
Just like for the past Lumen releases, the case has been produced from the noblest, all things considered: platinum. The drags and bezel are finely cleaned and the mid-case is straight brushed. 41mm in diameter, it features the crown and chronograph pushers on the right-hand side. The pusher on the left-hand side is for adjusting the outsize date. Each press advances the date one day. Overall, the case is the same as the regular Datograph Up/Down .
Turning the watch over, the show caseback offers a breathtaking perspective on the hand-wound section wheel caliber L951.7. The architecture, the profundity, the amazing completing of the 454-part development are essentially heavenly. The scaffolds and plates are crafted from untreated German silver: the flat surfaces are adorned with Glashütte striping and the balance chicken is engraved by hand. Four gold chatons are each held in place by three heat blued screws. The balance is free-sprung and features 6 capricious balancing loads. Running at 18,000 vibrations each hour, the beat can be adjusted thanks to a swan-neck.
Interestingly, the development is somewhat higher (8.1mm versus 7.9mm) than the regular Datograph rendition and it has more parts (454 versus 451) because of the adaptations necessary to make the development noctilucent.
A restricted release of 200 pieces, the A. Lange & Söhne Datograph Lumen Up/Down is worn on an alligator strap with a platinum pin clasp. Cost is set at EUR 95,000 (compared to EUR 82,500 for the regular Datograph). For more information, please visit www.alange-soehne.com .
