Lot Essay

The Tourbograph 'Pour le Merite Homage to F.A. Lange' was introduced in 2010 to celebrate the company’s 165th anniversary and as a tribute to its founder, Ferdinand Adolph Lange.

On 7 December 2005, A. Lange & Söhne commemorated the 15th anniversary of its reinstated manufacture with an inimitable expression of micromechanical virtuosity and watchmaking ingenuity. Testing the boundaries of physics and mechanical possibilities, for the very first time in the history of horology, the manufacture united three marvels from the realm of grand complications: a fusée-and-chain transmission, a tourbillon, and a split seconds chronograph mechanism in a single wristwatch.

Echoing the Tourbillon 'Pour le Mérite' that was presented in 1994, the Tourbograph once again unites the two most complex mechanisms dedicated to enhancing long-term rate accuracy, but Lange goes the further mile by integrating a timekeeping mechanism that allows lap times to be measured, as suggested by the name Tourbograph.

Attributed 'Pour le Mérite' - an accolade recognizing the superb horological skills of Lange's master watchmakers. The name alludes to the most prestigious order of merit, inspired by Alexander von Humboldt and sponsored by King Frederick William IV in 1842, awarded for outstanding, predominantly scientific accomplishments. The hand-crafted, manually wound L903.0 calibre comprises no fewer than 1'000 individual components. The tourbillon alone consists of 84 parts yet weighs a mere 0.5 grams. The finishing process of the bridge alone takes two days to complete.

Honey Gold
In 2010, Lange specially developed its own unique colour of gold, warm and lustrous, it is reminiscent of the colour of honey and was therefore named ‘honey gold’. The secret alloy includes 75% of pure gold and 25% of copper and zinc.

silicon which is physically harder and paler than standard 18k gold. Inspired by the colour of the gold cases of Lange & Söhne’s early pocket watches, ‘honey gold’ is only ever used for special limited edition timepieces such as the present watch and is therefore highly prized by collectors
