SIHH 2017: A. Lange & Söhne Introduces the Tourbograph Perpetual Pour le MériteThe flagship complication from Lange boasts a split-seconds, tourbillon, perpetual calendar, as well as chain and fusee.
The A. Lange & Söhne line-up at SIHH 2017 is half a dozen strong, and right at the very top sits the Tourbograph Perpetual “Pour le Mérite”, which builds on the first Tourbograph that was introduced in 2005.
The new Tourbograph adds a perpetual calendar to the original combination of split-seconds chronograph, tourbillon regulator as well as a chain and fusee constant force mechanism. This quartet of complications makes it the most complicated watch in the Lange catalogue, save for the gargantuan Grand Complication.
Comprised of 684 parts, the L133.1 movement inside the new Tourbograph has some 50% more components than the original. Consequently the watch expectedly larger than the original, with the case is sizeable 43mm in diameter and 16.6mm high.
Visually, however, the movement is nearly identical from the back, with majority of the changes taking place under the dial, where the perpetual calendar mechanism had to be installed in a narrow space.
And like most of the other Pour le Mérite equipped with a chain and fusee – there are now five of them – the new Tourbograph has a shortish 36-hour power reserve, because the chain and fusee mechanism takes up a significant amount of real estate.
Price and availability
Available at Lange boutiques and retailers in the last quarter of 2017, the Tourbograph Perpetual “Pour le Mérite” (ref. 706.025F) is priced at €480,000.
