Prestigious luxury watch manufacture A. Lange & Söhne presents an exclusive hand-worked version of a Perpetual Calendar Watch from its iconic 1815 line of watches. The dial and the hinged cuvette of the new 1815 RATTRAPANTE PERPETUAL CALENDAR HANDWERKSKUNST consist of blue enamelled white gold with elaborate relief engravings.
Ennobled with special decorative techniques, the movement stands out with the rare and fascinating combination of a split-seconds chronograph and a perpetual calendar with a Moonphase display.
Introduced in January 2013 at the Geneva Salon, the 1815 RATTRAPANTE PERPETUAL CALENDAR attracted considerable attention from lovers of fine luxury watches from all over the world. This watch is a technically and aesthetically convincing union of classic complications that rank among the most sophisticated mechanical ensembles in precision watchmaking. At the Grand Prix d’Horlogerie de Genève in that same year, the watch was not only the winner in the Grand Complications category but also won the Public’s Choice Award.
This remarkable timekeeping instrument was the ideal starting point for a limited 20-watch HANDWERKSKUNST edition. It is the sixth A. Lange & Söhne model with this attribute that stands for the particularly artistic decoration of the movement, dial and case.
The 1815 RATTRAPANTE PERPETUAL CALENDAR HANDWERKSKUNST confronted the finishers, engravers and enamel artists with an exciting challenge: to raise the decorative opulence for which the manufactory is known to the next level with rare and in some cases revived techniques as well as innovative ideas.
This is the first model to combine enamel art and engraving on its dial. Solid white gold is the substrate for the deep-blue enamel beneath which the sculpted contours of the relief engraved stars appear to be a visual extension of the moon-phase display. The Arabic numerals are flush with the enamel and harmonise perfectly with the rhodiumed white gold hands of the time and calendar indications as well as of the power-reserve indicator.
The colour of the enamel is echoed by the lunar disc as well as the blued-steel minute counter hand. These elements contrast exquisitely with the four recessed subsidiary dials in argenté-coloured white gold.
The chronograph hand offers an especially distinctive colour accent: it is crafted from gold-plated steel. The dial is framed by an argenté coloured flange ring with a traditional railway-track minute scale.
