It’s 1 metropolis of a movement, really like a small town of gears and plates. A complicated Lange, and especially a chronograph, will forever be among the most splendid-looking calibers in all of watchmaking history.As we have seen together with the Lange Double Split, there’s not just one, but 2 column wheels at the movement. As you can see on the picture above, this column wheel is directly linked to the two arms which control the splitting (or rattrapante) purpose: some extremely finicky geometrics come to play to prevent and let go of the wheel linked to one of both central chronograph seconds hands. Another column across the motion (the one to the left to the image below) serves as a regular chronograph function’s column wheel, responsible for stopping and starting the chronograph itself.There are easy moves that amaze with their finishing and you will find not-so-amazingly finished complicated movements that amaze with their overpowering design. The Tourbograph combines both and produces a watch that’s a sensual overload using a window onto a world where stunning surface treatments and decorations match with some of the hard geometrics and interactions of elements.
The latest from A. Lange & Söhne is almost a black and white rendition of its popular 1815 Chronograph – a dial in black and silver combined with a white gold case. It’s not a novel look, but it is a good one.
Palette aside the 1815 Chronograph in black is identical to the earlier versions of the watch. The dial is solid silver, just like nearly all Lange dials, with a pulse rate scale on the periphery of the dial. Graduated for 30 heartbeats, the pulsometer was originally designed for a doctor or nurse to measure a patient’s heart rate conveniently.
The white gold case is 39.5mm in diameter with the L951.5 movement inside. That’s the second generation Lange chronograph calibre featuring an extended 60-hour power reserve (compared to just 36 on the first generation) as well as a free-sprung, adjustable mass balance wheel.
Unlike the flagship Datograph, the 1815 Chronograph lacks a date function, which is why it is a relatively slim 11mm high.
Price and availability
The 1815 Chronograph in black (ref. 414.028) is priced at €49,000 or S$67,700. Unlike the blue and white version of the same, the black dial model is not a boutique-only watch. It is already available at retailers and boutiques.
