The Saxony brand A. Lange & Söhne, introduced its latest version of grand complication models that brings together the Rattrapante and Perpetual Calendar features under the same roof. Every year since 2011, A. Lange & Sohne has a very special tradition the brand creates an exclusive, limited-edition Handwerkskunst translates as “craftsmanship”. Handwerkskunst timepieces as they are quite rare and known as the crème de la crème product line of the famous German brand.
And now A. Lange & Sohne introduces the sixth 1815 Rattrapante Perpetual Calendar Handwerkskunst grand art watch and it is a beauty thanks to the stunning blue enamel dial in full-blown starry night motif. The 6th edition is no exception to the rule. Indeed, it is based on the complex 1815 Rattrapante Perpetual Calendar, which as indicated by its name, combined a split-seconds chronograph and a perpetual calendar, so-to-say a sort of holy grail for collectors. As complex as it is mechanically-speaking, the habillage remained very much Lange: pink gold or platinum case, a silver dial and blued hands.
The night sky illustration that we see on the moon phase indicator’s disk seems to be used as a background for the dial itself sporting translucent vitreous enamel star figures made by using the Champlevé technique. The hand-wound caliber L101.1 features German-silver bridges finished in a granular texture with additional engraved star details. The hands for the time-keeping, calendar indicators and power reserve display are in 18K white gold while the minute counter hand is in flame blued steel. Both split-seconds hands are also steel, but one is gilded for easy reading.
Aside from this decoration, the L101.1 remains unchanged compared to its siblings and still uses a pair of column wheels to control its split-seconds chronograph. Its perpetual calendar mechanism is set to compensate for the duration of months—and upcoming leap years until 2100—and its moon-phase indication is said to be accurate for the next 122.6 years. This new release will be limited to 20 pieces worldwide, priced at 290,000 Euros.
