For the Golden Complications chapter, Jaeger-LeCoultre presented the Reverso Tribute Tourbillon, with an ultrathin calibre, a fully flying tourbillon visible on both sides of the case. The watch has a night and day indication, the calibre is 3.9mm thick (or thin, actually) and is hand-decorated in the Atelier des Metiers Rares. The ”guilloche clou de Paris” pattern necessitated 1392 lines, drawn by hand. There is also a second timezone on the back. The watch will retail for 43,000 euros.

For the Reverso Tribute Chronograph, Jaeger-LeCoultre had to completely reinvent the chronograph, which normally works in a round case, to make it fit into a rectangular one. The watch has a retrograde 30-minute chronograph counter, an openworked verso, a dial reduced to a minimum. The watch is available in steel (20,000 euros) and gold (30,000 euros). The Reverso Tribute Small Seconds sports an ultrathin case, 1mm thinner than the current one. We loved the burgundy lacquer dial.

We must mention the chef d’oeuvre – the Reverso Hybris Artistica Calibre 179 – a fully flying gyrotourbillon. Ten pieces will be made, at 500,000 euros per piece.

And we end on a very high note, with the charming Reverso One Precious Colours – two small masterpieces by a ”maître emailleur” handpainted Grand Feu miniature enamel in a mosaic pattern. These are lovely Art Deco watches in five different shades of green or blue, with 277 diamonds each.
