The Jaeger-LeCoultre Manufacture brings together some 180 different watchmaking specialities necessary for the complete design and manufacture of watches: from the most recent technologies to the oldest and rarest crafts. The enamel miniature painting studio is home to skills that have all but vanished. It adjoins the engraving studio, where artisans delicately hollow out the metal to embellish the most prestigious watches and movements. In the purest Art Nouveau style, this pendant watch being auctioned by Artcurial has a polychrome engraved, chased and enamelled 18-carat yellow-gold case. The grand feu enamel dial is marked with metallic markers integrated into the enamel and painted Arabic numerals. With its cylinder escapement, the LeCoultre 9HN calibre barely reaches 2 cm in diameter. Its half-hidden “LeCoultre” winding system was protected by a patent filed in 1894.
