http://www.thewatchbox.com/watches/jaeger-lecoultre/#watches The Jaeger-LeCoultre Reverso is a watch that requires no introduction. Launched in 1931, the Reverso has become the quintessential Art Deco watch design, an icon of its era, and the flagship line of Jaeger-LeCoultre. More than a watch, the Reverso is a virtual institution, a cult watch, and a cultural phenomenon. Launched in 2009, the Jaeger-LeCoultre Grand Reverseo 976 translates the classic Reverso proportions to a scale that suits modern tastes and modern wrists. The Reverso "XGT" case debuted as a platform for complications in 2002 on the Reverso Septantieme anniversary edition, but it wasn't long before collectors clamored for the larger case in an aesthetically pure time-only format. Jaeger-LeCoultre complied. The Grande Reverso ups the ante from the Grande Taille case's 42mm and 26 lug-to-lug and width measurements, respectively. This XGT case in 18-karat rose gold measures a satisfying 46.5mm lug-to-lug and 28mm in width. Combined with the heft of rose gold, the difference in wrist presence is substantial. All of the original model's styling hallmarks are retained; witness the deep horizontal gardrons, the rich silver guilloche dial, the stark Arabic numerals with vertical emphasis, and the gorgeous cobalt blue broadsword hands. But rotate the hinged case, and the Grande Reverso 976 reveals a modern innovation: the caliber 976 movement. Based on the 21st-century "auto tractor" movement, the Caliber 976 adopts that automatic system's most rugged design elements while shedding the bulk of the automatic winding system. The manually wound cal. 976 features a robust full balance bridge, a freesprung balance, a laser-welded hairspring (at stud and collet), and 48 hours of power reserve. Because JLC is a true manufacture, the caliber 976 has been designed to fill the display case back of the Grande Reverso from top to bottom. With classical style and modern dimensions, the 18-karat rose gold Jaeger-LeCoultre Grande Reverso is a timeless design that's ready to tackle our times.
