A. Lange & Söhne Goes Green With Its New Lange 1 “Lumen”

As a brand with a non-anglophone name that makes just 5,000 watches each year, A. Lange & Söhne’s latest creations might not spark as many headlines as Rolex or Audemars Piguet, but that’s just as its many die-hard aficionados would have it. To paraphrase the brand’s colourful longtime director of product development, Anthony de Haas, “A. Lange & Söhne is for the nerds and the geeks.” Fortunately for them, the brand unveiled two extremely alluring editions of two of their most coveted models.

Lange 1 Tourbillon Perpetual Calendar “Lumen”

This new release combines two of A. Lange & Söhne’s most distinctive calling cards: the Lange 1 and the Lumen series. The former, which combines an oversized date window with an hour and minute subdial, is the brand’s signature watch design. Meanwhile, the latter denotes the addition of a transparent luminous disc in place of a conventional dial. Add to that the irresistible appeal of a perpetual calendar and tourbillon powered by a newly developed movement, and you’ve got a recipe for enthusiast catnip. One could spend a lot of time detailing everything that makes this watch and its movement such a masterpiece of modern horology, but — as the kids say — if you know, you know. Suffice to say that the Lumen dial is cool for two main reasons. First, it’s transparent and luminous. And second, it further emphasizes the movement, which is the star of the show.

Saxonia Annual Calendar

One of the stars of Watches & Wonders 2025 was the new A. Lange & Söhne 1815, whose 34mm-wide-by-6mm-thick case tickled the fancy of just about every watch snob in the building. The new Saxonia Annual Calendar takes a page from the same playbook, with similarly enticing results. Measuring 36mm across the case and just a hair under 10mm thick, this new release offers one of the watch world’s favourite complications in a scaled-down — and extremely enthusiast-friendly — size. Of course, Lange being Lange, that’s not all. Powering the hours, minutes, seconds, day, date, month, and moon phase is a new automatic movement that allows all calendar indications to be adjusted individually with separate correctors or advanced collectively with a convenient pusher at 10 o’clock. Subtle? Yes. Esoteric? Most definitely. But that won’t stop this right-sized stunner from appearing on just as many Best of Show lists as last year’s 1815.
