2013 Jaeger-LeCoultre Grande Reverso Ultra Thin 1931 Duoface
A Reverso with a lovely vintage-inspired white dial, a second face in black, and the JLC 854/1 hand-wound movement.
Overview
The story of the Reverso began in the late 1920s when British officers stationed in India requested a watch that could withstand the rigors of playing polo. In response, the watchmakers at Jaeger-LeCoultre ingeniously created a hinged slide mechanism that flipped the case over to safely protect the watch face during play. While it was built to withstand the rough and tumble of the game, the design of the Reverso remained elegant and simple with decorative lines, streamlined contours, and a minimalist aesthetic.
In the early 2010s, nearly 80 years after its creation, Jaeger-LeCoultre began paying homage to the design of the 1931 Reverso through a series of Tribute models that bore the same sword hands, dart indices, and simple “Reverso” branding as the original. While the initial Tribute models opted for the monoface casing, the brand eventually released this Grande Reverso Ultra Thin 1931 Duoface containing a white opaline dial for tracking the time at home, and a Clous de Paris black dial on the reverse side for tracking the local time while away. In addition to giving the wearer a choice between the two different dials, the 1931 Duoface lives up to its Ultra Thin moniker with a discreet 9.3mm case that allows it to seamlessly slide under any jetsetter’s sleeve.

The lugs are nice and strong with even contouring. The reversing chassis is clean with no imperfections to note. The brushed finish of the case back shows no scratching and the engravings remain sharp and deep.
Dial, Hands, & Crystal: Both dials and their respective handsets are in perfect condition. The Super-LumiNova within the hands on the reverse side is fully functioning and consistent. Both sapphires are squeaky clean and scratch-free.
Bracelet/Strap: The JLC navy alligator strap shows minor signs of wear including slight creasing on the backside near the first hole. Other than that, there is no major staining or fraying.
