F.P.Journe Astronomic Souveraine Grand Complication Watch

After the success of the prototype’s sale at the Only Watch auction, F.P.Journe presents the final version: Astronomic Souveraine. It is a grand complication watch in a steel case, housing 18 complications including tourbillon and minute repeater. This exceptional creation was unveiled on 14 November in Tokyo at first flagship boutique of the brand.

The Astronomic Blue, the prototype of this grand complication, developed specifically for Only Watch 2019 Charity auction, was sold for the amount of CHF 1’800’000.-, a new world record for an F.P.Journe watch.

The 18 carat rose Gold movement of the Astronomic Souveraine is totally novel and very finely decorated. The white Gold dial, whose sub-dials are embellished with clou de Paris decoration, and the moon phases, with a hyper realistic moon that was traced from a NASA photograph.

At 3, there is the mean time (or civil time) dial, with a blue hand indicating a second time zone. At 9, there is the sidereal time dial, which allows the observation of the stars. Next to it, the mean time seconds are shown on a disc. Between the two are the central minutes and the power reserve indication, which remains optimal up to 40 h. Above all this is a blue aperture showing the sunrise and sunset. Here, metal shutters lengthen or shorten the days.

On the reverse there is the equation of time and a full annual calendar encircled by the signs of the zodiac. It is on this side that the dance of the tourbillon may be admired. In all, this watch, which also strikes the hours, the quarters and the minutes, possesses 18 functions and complications.

It is made up of 758 components, in addition to the case. However, the case is no larger than 44 mm in diameter and 13.80 mm thick. Only a very few pieces of the Astronomic Souveraine will be produced each year.
