A. Lange & S\u00f6hne has unveiled a new Lange 1 Tourbillon Perpetual Calendar, this time given the \u201cLumen\u201d treatment, featuring a smoked sapphire dial that allows UV light to charge the luminous compound on the underlying displays.
\nThis new Lange 1 integrates a tourbillon with a patented stop-seconds mechanism and a perpetual calendar featuring instantaneously switching displays, as well as the brand\u2019s first luminous moon-phase with a day\/night indication.
\nLimited to only 50 pieces, the watch is powered by the 685-part manufacture calibre L225.1 and is housed in a 41.9 mm 950 platinum case with extensive hand-finished, artisanal details.<\/p>\n

If you took the time to read my recent piece introducing A. Lange & S\u00f6hne\u2019s newly revealed, and painfully gorgeous Saxonia Annual Calendar<\/a>, you\u2019ll know that I mentioned that one of the brand\u2019s most consistent strengths is balance. It\u2019s a challenging task to bring together several complications into a watch that is not only sensibly sized but also has unique, often genre-defining aspects. And while the Annual Calendar is a lesson in restrained, complicated elegance, Lange has another surprise in store for Watches and Wonders 2026. The Lange 1 is one of the brand\u2019s most iconic models, and this year it receives a similar luminescent upgrade that we saw given to the Datograph Lumen a couple of years back<\/a>; a smoked, sapphire dial that allows the fully lumed components to glow brilliantly, all while exposing the tourbillon-regulated perpetual calendar movement inside.<\/p>\n

\"a<\/p>\n

The case is typically Lange 1, albeit slightly on the larger side, but this is a complicated piece, so it can be forgiven. The 950 platinum case measures 41.9mm in diameter and, at 13mm thick, certainly has wrist presence. Both sides of the case are sealed with sapphire crystals, and the flanks are subtly interrupted firstly by the crown that takes care of winding and setting the time, but then by a main corrector for jointly advancing the calendar indications, then a corrector for changing the days, month, and moon phase.<\/p>\n

\"a<\/p>\n

Importantly, there\u2019s no surface finish on the dial to froth over, because it\u2019s crafted from a single piece of smoked sapphire, with two apertures near the top for the signature outsized date windows. This smoked sapphire is there to allow the date wheel, moonphase, and date indicator, which are all covered in luminescent compound, to be charged in daylight, and of course, to shine through the sapphire, illuminating the entire dial when the lights go out. This is accentuated by luminous hands and several other markers across the dial, creating the most striking effect possible.<\/p>\n

\"a<\/p>\n

Visible through the dial and the sapphire exhibition caseback is the calibre L225.1 self-winding perpetual calendar movement. It comprises 74 jewels and 684 components, which, when working together, offer a 50-hour power reserve and oscillate at 21,600 Vph, regulated by a beautifully finished tourbillon. As you would expect, the fabulous finishing extends everywhere else, to the German silver bridges, hand-engraved tourbillon cock, and winding rotor which features a centrifugal mass crafted from 950 platinum.\u00a0<\/p>\n

\"a<\/p>\n

Completing the Lange 1 Tourbillon Perpetual Calendar is a black, hand-stitched alligator leather strap, complete with Lange\u2019s beautiful deployant quick-lock buckle, also crafted in case-matching 950 platinum. The biggest problem with this Lange 1 will, sadly, be getting one, assuming you can already afford it. There will only ever be 50 watches, so it\u2019s going to be pretty rare, although there is no doubt that you will be able to spot one in the dark.<\/p>\n
