After the success of Only Watch 2019, F.P.Journe presents the current collection version of the prototype that was offered at auction: the Astronomic Souveraine. It is a grand complication watch in steel, with tourbillon and minute repeater. Entirely devoted to the observation of the stars, it has 18 functions and complications.
The 18 ct rose Gold movement of the Astronomic Souveraine is totally novel. And it is, of course, very finely decorated. For example, 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 3h, there is the meantime (or civil time) dial, with a blue hand indicating a second-time zone. At 9h, 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.
