A. Lange & Sohne – Richard Lange Tourbillon “Pour le Mérite”
The Richard Lange collection of A. Lange & Sohne is committed to Ferdinand A. Lange’s child, an extraordinary watchmaker with a logical turn of mind who enrolled a number of licenses that promoted the development of Lange timepieces.
Already available just in platinum and pink gold, the Richard Lange Tourbillon “Pour le Mérite”, a complication watch that joins A. Lange & Söhne’s one of a kind fusée-and-chain transmission and a one-minute tourbillon with a protected stop-seconds mechanism, is being presented in a white-gold adaptation with blued steel hands and blue minutes scale markers for ideal legibility on the argenté-shaded strong silver dial. This form will be available just in A. Lange & Söhne shops, remembering those for New York and Moscow that just opened for this present month.
Since the introduction of its first new-time watch collection 20 years prior, the “Pour le Mérite” hallmark has been alloted by A. Lange and Sohne to only four exceptional timepieces, every one of them coordinating the fusée-and-chain transmission, which in this model is uncovered through the openings in the three-quarter plate.
The proprietor can see how the many-sided 636-section chain loosens up from the mainspring barrel onto the fusée while the watch is being wound.
The fusée-and-chain transmission is perhaps the most powerful complications with regards to expanding the rate exactness of a mechanical watch. Truth be told, the force created by a spring is high when it is completely tensioned and essentially more fragile as it approaches the completely loosened up state. This can cause rate-exactness changes. The fusée-and-chain transmission levels the fading power of the slowly loosening up mainspring and makes sure that the movement consistently gets a steady amount of energy.
The one-minute tourbillon for best rate dependability includes a modern stop-seconds mechanism which makes it possible to quickly hinder the equilibrium inside the tourbillon pen and consequently stop the movement simply by pulling the crown. This permits the watch to be set to one-second precision.
Moreover, the Richard Lange Tourbillon “Pour le Mérite” shocks with an inventive and furthermore protected rotating dial segment: from 6 to 12 o’clock, a small helper dial fills the hole in the hour circle, which at all different times uncovered the entrancing tourbillon.
The controller dial shows the time signs with independent shows, a format straightforwardly roused by Chronometer No. 93 made by Dresden watchmaker Johann Heinrich Seyffert (1751–1818).
The white gold instance of the new Richard Lange Tourbillon “Pour le Mérite” (ref. 760.026) has a diameter of 41.9 millimeters and a stature of 12.2 millimeters. The cost is US$ 212,900/Euro 171,900.
