Entirely openworked and decorated by hand, the mechanical movement of the Grande Reverso Ultra Thin SQ reveals ist wheel-trains fascinatingly interwoven according to a purposefully created design that leaves nothing to chance.

Blue. Infinitely blue. The Grande Reverso Blue Enamel draws the gaze towards the ocean depths of its Grand Feu enamel dial. It reveals a pure and timeless face entirely in line with the spirit of a now legendary collection. Crafted in the finest traditions of enamelling, an art with ancient roots, its enamelled white gold dial has undergone around 20 firings in the oven at 800°C in order to achieve this electric blue shade vying with the azure hue of the heavens. The last layer of translucent enamel endows it with exceptional purity and brilliance destined to serenely stand the test of time.
The traditional type of gem-setting allows the craftsman to add a personal touch to the motif. He decides on the exact placing and the number of stones to be set, and the design of the motif, on the creation entrusted to him. Blued screws are dotted across this delicate lacework, while the jewels are there as a reminder that this is a first-rate mechanical manually-wound movement, Jaeger-LeCoultre Calibre 849RSQ.
The latter has become a legend because of its exceptional qualities including a frequency of 21,600 vibrations per hour and an ultra-thin 1.85 mm thickness comprising 128 parts. Its extremely slender architecture calls for exceptional machining precision, while its openworking adds to the complexity of the task and represents an impressive accomplishment. In order to honour this exquisitely meticulous work, the white gold dial is framed by finely engraved arabesques, accompanied on the front by a blue-tinted translucent enamel coating echoing the traditional colour of the blued hands.
Issued in a 50-piece limited edition, the Grande Reverso Ultra Thin SQ radiates emblematic Art Deco lines and peerless finesse highlighted by rare forms of craftsmanship inherited from the past and handed down from generation to generation within the Manufacture. [Jaeger-LeCoultre]
