This is the new A. Lange & Söhne 1815 Tourbillon. The tourbillon is totally visible, and the case is pretty beefy – two things I generally dislike about a complicated watch, but I don’t dislike them here. The reason is this new tourbillon, which pays obvious homage to the first Lange tourbillon pictured above, complete with giant tourbillon cage at 6 o’clock and massive horizonal bridge, set on a simple silver dial with printed numerals. It is incredibly simple looking, with a super slick technical side that many would never take the time to pay attention to, all with the focus of precision time keeping.
You see, this tourbillon features two patented systems that allow for the easiest and most precise time-setting one could ask for. The one-minute tourbillon, clearly visible at 6 o’clock, is automatically stopped when one pulls out the crown (consider this a “hacking” mechanism for all you vintage folks out there). There is a blue-steeled hand indicating subsidiary seconds, clearly connected to the tourbillon.
