A Lange & Söhne’s 1815 Rattrapante Perpetual Calendar Handwerkskunst Is A Mark Of True Craftsmanship
And it's a multi-winner too.
First seen at the Geneva Salon in 2013, the initial iteration of the 1815 Rattrapante Perpetual Calendar garnered considerable attention in the horology community and was seen as a technically and aesthetically sophisticated complication. At the Grand Prix d’Horlogerie de Genève in that same year, the watch not only won in the Grand Complications category, but also walked away with the Public’s Choice Award.
This year, the Handwerkskunst edition, the sixth model of the 1815, challenged the finishers, the engravers and the enamel artists to raise the opulence and the technical sophistication to a whole new level. Ennobled with special decorative techniques, the movement stands out with a unique combination of a split-seconds chronograph and a perpetual calendar with a moon-phase display.
This is the first model to combine enamel art and engraving on its dial. Solid white gold is layered beneath the deep-blue enamel showing off the stars on the moon-phase display. The Arabic numerals are flush with the enamel and complements the rhodiumed white-gold hands of the time, the calendar and the power-reserve indicators.
These elements contrast exquisitely with the four recessed subsidiary dials in argenté-coloured white gold. The chronograph hand offers an especially distinctive colour accent crafted from gold-plated steel. The dial is framed by an argenté-coloured flange ring with a traditional railway-track minute scale.
With only 20 pieces available, the 1815 Rattrapante Perpetual Calendar Handwerkskunst is one of A Lange & Söhne’s standout creations.
