The A. Lange & Söhne Tourbograph Perpetual “Pour le Mérite” knows a couple things about bringing complicated watches to fruition. Their latest is one of their most complex yet and has a movement that features a staggering 684 components. All those pieces come together to seamlessly drive five complications that include a perpetual calendar, chronograph, rattrapante function, a one-minute tourbillon, and a fusée-and-chain transmission.
The dial design is an immaculate arrangement of classic details, from the Arabic numerals to the railway-track minute scale. You'll also find thermally blued screws, six screwed gold chatons, and silver bridges and plates with Glashütte ribbing and perlage. The 43-mm watch will come in platinum and will be limited to just 50 pieces.
