Instant-jump time-zone watch with mechanical memory.

An exclusive mechanical complication with an instant-jump time-zone display. This technical feat is accomplished via the pusher and the crown. Having selected the first city’s time and date, the owner of the watch needs only to set the second city. The watch mechanism then calculates the time and date by means of a clever system of cams, hammers and an integrated differential. At that point, simply pressing the pusher is enough to travel from one end of the planet to the other, all without disturbing the accurate running of the watch.

Another key feature of the Hora Mundi is the dial: this one offers a fascinating interpretation of the world on the wrist by a play on materials and superimposed plates which gives depth to the dial. The first gold base is composed by hand-guilloché waves. An additional sapphire plate displays the luminescent gold hour-markers along with the engraved and varnished navy blue continents. For this special edition, and as a reminder that the planet never sleeps, multiple bright rose gold dots stand out on Earth. Finally, an external flange holds the various elements present on the dial.
