The A. Lange & Söhne Tourbograph "Pour le Mérite" is a landmark in German watchmaking, combining three of the most demanding complications: a one-minute tourbillon, power equalization with fusée-and-chain transmission, and split-seconds chronograph. Introduced in 2005, it was the first watch to integrate all three, showcasing Lange's technical mastery.
At its core is the hand-finished calibre L903.0, composed of over 1,065 parts. The fusée-and-chain mechanism alone includes a 15 cm chain made of 600 components, weighing just 0.12 grams yet capable of lifting 2 kg-ensuring consistent torque and precision.
Only 101 pieces were made-51 in platinum, 50 in gold-with just 12 produced annually. Its rarity and engineering excellence make it one of the most coveted timepieces in haute horology.
