Jaeger-LeCoultre Reverso Tribute Nonantième
If we wind back all the way to March 4, 1931 that was the date on which René-Alfred patented the invention of a “wristwatch that can slide on its base and flip over on itself” at the INPI (National Industrial Property Institute) in Paris. Hence from that moment on the “Jaeger-LeCoultre Reverso'' came into being and is currently celebrating its 90th anniversary. Along these nine decades we’ve seen various iterations, but the latest “Jaeger-LeCoultre Reverso Tribute Nonantième” has managed to introduce a complication that had never been featured in a Reverso until now.The 29.9mm rectangular case is made of 18k pink gold with its iconic reversible portion capable of smoothly swiveling out to allow the front or the back to be visible.
On this model the flip-side reveals its complications in a different configuration (as we further detail below), which can become the user's main display with a simple swivel flip, thanks to its patented design. 
Unlike slimmer Reverso’s that tend to measure in at only 8.5mm, this version has a slightly thicker 11.72mm casing. All topped by a sapphire crystal that assists with water-resistance on this watch reaching up to 30 meters (96 feet).
Time is exhibited on a silvered grey dial with a sunray-brushed finish. It features 18k pink gold applied hour index markers, followed by smaller black printed railroad-motif minute index markers that adhere and reinforce its rectangular shape. 
There is also a sub-seconds dial that spreads out, taking up much of the dials lower-half. 
Within this small seconds sub-dial is a very detailed moonphase, adored with golden stars.
It comes equipped with central pink gold dauphine style hands. All these index markers and the sub-seconds have been meticulously applied by hand. The upper-half of the dial includes the full “Jaeger-LeCoultre” logo, underneath a two-window big date aperture outlined in a gold frame.
As we swivel over on the flip-side we encounter a tribute to the 1930's in the form of a digital display. A few functions disappear, but we're left with a truly original example of artistic ingenuity.
Among a background of mostly pink gold at the center is a round shape that draws our full attention. This digital hour and minute display is further embellished by a beautiful Night & Day indication. 
As described by the official Jaeger-LeCoultre press-release: "Polished golden stars shimmer against a blue sky lacquered with a sun-ray brushed satin finish." And at the center where the sun and the moon drift by the JL logo is engraved on a guilloché background.
