RDSChicago initiates a compelling discussion on the A. Lange & Söhne Lange 31, a timepiece renowned for its extraordinary 31-day power reserve. This article delves into the community's perspective on its practicality, wearability, and the horological significance of its ambitious engineering. Collectors weigh in on whether its groundbreaking mechanics outweigh its substantial wrist presence.

You need to buy two. One for each wrist. You won’t need to do any delt work at the gym. Of course a gym membership is less expensive.
A bold and audacious concept (as with the Double / Triple Split, the Zeitwerk...), including the ratchet-key wind. An amazing feat of German engineering - stacking two 6-foot long mainsprings and funnelling all that energy through a remontoire. But mostly, another great example of the then still young reborn Lange "learning by doing". That double-stacked mainspring architecture (though not 6-foot long!) is now on the current generation Zeitwerk, as is a remontoire of course. I was fortunate to b
Great description Aviya. I’ve always loved the clean look, but probably too impractical and a bit expensive.
And as others said, that R&D eventually led to the zeitwerk. I think it will be fascinating if one day Lange revisits the complication in an wearable format.
Apart from that it is a monumental (pun intended) collector's piece, that I would love to own!
As you likely know, the winding key is actually a miniature torque wrench with a planetary-geared slip that prevents you from over-winding the watch. Really quite ingenious.
