A. Lange & Söhne, Glashütte i/SA, "TOURBOGRAPH Pour le Mérite", Movement No. 40044, Case No. 150107, limited edition serial number 7/50, Ref. 712.050, Cal. L903.0, 41 mm, circa 2010
An important and extremely rare Glashuette wristwatch in mint condition, with visible one-minute tourbillon and split seconds chronograph. It is the first one-minute tourbillon in a wristwatch format with a fusée-and-chain transmission as well as an additional rattrapante chronograph - produced in a special series limited to only 50 pieces in 18k honey gold - with original box, loup and cleaning cloth, A. Lange & Söhne Proof of Origin, operating instructions, Lange-booklet and Lange-guarantee seal dated July 5, 2010
Case: 18k honey gold, sapphire glass screwed on back, limited edition serial number on the caseback, "Lange" 18k honey gold buckle. Dial: solid silver, argenté, engine-turned centre, blued steel hands and rhodium-plated split seconds gold hand.
On occasion of the company’s 165th anniversary in 2010, A. Lange & Söhne commemorated the spiritual legacy of company founder Ferdinand Adolph Lange with a trilogy of timepieces with exceptional complications and named it "165 Years - Homage to F. A. Lange". The individual limited models were available independently and only 21 sets consisting of the three timepieces "1815 MONDPHASE", "TOURBOGRAPH 'Pour le Mérite'" and "LANGE 1 TOURBILLON" were available in total -one of them was presented during our autumn auction in November 2019. All timepieces of this special edition come in 18K honey gold; this new type of gold alloy is significantly harder than any other gold alloys and was developed exclusively for A. Lange & Söhne.
The "TOURBOGRAPH 'Pour le Mérite'" is especially remarkable because of its technical sophistication. It features a minute tourbillon powered by an unusual mechanism using chain/fusee, which is considered particularly difficult to implement in a wristwatch. This complicated timepiece is also fitted with a rattrapante chronograph function visible through the crystal caseback. The delicate tourbillon cage can be observed from the front as well as through the sapphire crystal back. The watch is fitted with Lange’s proprietary manual wind calibre L903.0.
