A. Lange & Söhne Zeitwerk Honeygold Lumen and its new powerful movement
If A. Lange & Söhne watches often use classic design cues, then there is a sub-series that must have a more modern and technical atmosphere, and that is the so-called Lumen series limited edition. The series was born in 2010 in Zeitwerk Luminous (not yet named Lumen) and has now grown into one of the most popular and most popular watches in the brand’s product portfolio. These watches with sapphire dials are rare and unique, making them the best choice for collectors. They will be happy to know that a new watch has been launched today, it is back to its roots, based on an architectural watch with jumping instructions… But as you can see, this brand new Zeitwerk Honeygold Lumen has many new features, starting from one An unprecedented powerful movement began. Moreover, it is also the first Lumen not made of platinum…
Behind the Luminous/Lumen series, there is a very interesting story. The brand’s director of product development, Anthony de Haas, wore an early version of the platinum Zeitwerk and found it difficult to read the time in the dark. Therefore, he and his team began to explore how to make this modern-looking watch more readable at night…Once the disc had luminous numbers, it was created by adding parts-however, the colored sapphire dial is quite special , Because it allows ultraviolet rays to pass through in order to charge the digital light. This is the beginning of the Luminous/Lumen series.
2010 – Zeitwerk luminous “lumens”
At the time it was not named Lumen (it appeared with the second watch), the first watch in the series was Zeitwerk Luminous, based on the classic version launched in 2009, the GPHG champion. This watch comes with a reference. 140.035 is made of platinum with a dark sapphire dial. The disc with luminous indicators appears below and partially shows some technical parts of the movement. This is a limited edition of 100 pieces. Other aspects are the same as the classic Zeitwerk, with skipping hours on the left disc and skipping minutes on the two discs on the right. The movement is almost the same as the classic Zeitwerk model, the manual winding movement L043.3, the frequency is 2.5Hz, the power reserve is 36 hours, and it is equipped with a patented one-minute remontoire mechanism.
2013 – Grand Lange 1 Lumen
Following Zeitwerk, the brand launched the second Lumen watch based on Grand Lange 1 in 2013 to fully demonstrate the classic A. Lange & Söhne large date function, which can be seen through the window at 2 o’clock, but it can also be seen in some parts. -Colored sapphire dial. This 41 mm watch, reference number 117.035, is limited to 200 pieces and is made of platinum. All indicators are luminous (hours/minutes, all hour markers, small seconds, power reserve, and of course the big date). Inside is the manual winding movement L095.2, with a 72-hour power reserve and the same mechanical base as the classic closed dial Grand Lange 1.
2016 – Grand Lange 1 Moon Phase Lumen
This model was launched in 2016 with a reference number of 139.035 and a limited edition of 200 pieces. It is also made of platinum and has a diameter of 41 mm. This is an evolution of the concept introduced in 2013, but the star shown here is the luminous moon phase indicator integrated in the hour/minute off-centre dial. Just like the previous Grand Lange 1 Lumen, all displays including the large calendar are coated with luminous material, so some displays can be seen under the partially colored sapphire dial (mainly the date dial). The moon disk is decorated with many small luminous stars. Inside the case is the manual winding movement L095.4, which also has a 72-hour power reserve and the same base as the classic Grand Lange Moon Phase (non-lumen).
2018 – Datograph lumens rise/fall
Following the previous 3 watches, A. Lange & Söhne launched a new 200 Lumen limited edition in 2018, again made of platinum, but this time based on its most famous chronograph Datograph. Reference 405.034 The idea of using a partially colored sapphire dial again is to emphasize the two main complications of this model, by partially revealing the mechanism behind the oversized date, and by making the chronograph function highly visible in the dial in black, because the sub-dial and the tachymeter ring are coated There are luminous materials. The sapphire dial can also see the top of the movement. Finally, the Up/Down power reserve function is also highlighted with luminous materials. The platinum case diameter is still 41 mm, the movement is the same as the updated version of Datograph, and it has a 60-hour power reserve. The hands and some rod-shaped hour markers also glow.
