In 1997, Jaeger-LeCoultre introduced the Reverso Duetto, featuring two back-to-back dials, each with a set of hands driven by a single movement but turning in opposite directions in order to display the same time correctly on both sides – a complex mechanism that represented a technical achievement for the Manufacture’s watchmakers. For the new Reverso One Duetto Jewellery models, the hand-wound Jaeger-LeCoultre Calibre 844 – entirely developed and produced within the Manufacture – now promises 50 hours of power reserve.
The new Jaeger-LeCoultre Reverso One Duetto Jewellery presents the back-to-back dial concept in a new setting that is as rare as it is precious. With 335 grain-set diamonds that cover the entire case-back and wrap seamlessly around its curved sides to frame the dial, the case is unquestionably a piece of jewellery, emphasised by the inverted diamond set into the crown. On the front, every detail of the silvered sunray dial with its guilloché decoration is delicately finished: the golden brackets in each corner, the applied Arabic hour numerals and hour markers, the Dauphine hands – all emblematic elements of the Reverso One models.
The reverse dial offers a striking contrast – dramatic and more mysterious. Enhanced by Art Deco-style gold hour markers – also emblematic of the collection – the black dial immediately catches the eye. Sprinkled across a background of glossy black lacquer, tiny gold flakes seem to form clusters of light particles, their radiance echoing the brilliance of the diamonds that adorn the case.
The Jaeger-LeCoultre Reverso One Duetto Jewellery raises the Duetto concept to even greater heights with a diamond-set bracelet – the first time that the case, bracelet attachment and bracelet links of a Reverso One have been fully gem-set. A total of 719 diamonds adorns this High Jewellery piece, including at least 384 for the bracelet alone.
To create the case and bracelet of the new Jaeger-LeCoultre Reverso One Duetto Jewellery , the gemsetters in Jaeger-LeCoultre’s Métiers Rares workshop used the grain-setting technique, anchoring the diamonds with tiny, almost invisible gold beads that give the precious stones an unparalleled sparkle. Setting four diamonds together in perfect symmetry within the tiny dimensions of each pink gold link is testament to the gemsetters’ mastery of their craft.
The new Jaeger-LeCoultre Reverso One Duetto Jewellery reaffirms the watchmaking expertise and jewellery savoir-faire that La Grande Maison has cultivated with passion for several decades.
