Four or five leave the workshop each year. The Astronomic Souveraine is the production form of the watch Journe built for Only Watch in 2019, and it carries eighteen functions across two faces, which makes it the most complicated thing the house sells. Steel is the case metal, chosen the way Journe chooses steel for all his chiming watches, because the crystalline structure carries sound better than gold or platinum does and this watch has a minute repeater inside it. That is the whole argument for a steel grand complication, and it is the opposite of the argument most houses make about case materials. Everything else about the watch is as elaborate as watchmaking gets.
The case is steel at 44 mm across and 13.8 mm deep, polished throughout, and it is the largest thing in the collection alongside the vertical tourbillon. Size here is a consequence rather than a choice, since eighteen indications need somewhere to go. The dial is solid white gold with whitened guilloche silver let into the registers, and the layout is symmetrical in a way that eighteen functions has no right to be: hours and a second time zone at three, minutes from the center, sunrise and sunset at twelve, sidereal hours and minutes at nine, a moon phase on a sapphire disc at five and seconds on a rotating disc at seven. Blued steel and gilt 5N steel hands separate the indications by color rather than by shape, which is what keeps the face readable. The reverse is a second dial rather than a display back, carrying the equation of time from the middle and an annual calendar with a zodiac scale at ten, with the tourbillon turning below it. Both faces are covered in sapphire and the case band is broken only by the crown. Steel at this size and this thickness is heavier than it looks in photographs but lighter than the same case would be in platinum, which is part of why the watch is wearable at all. The finishing is the standard applied to the precious metal references rather than a lesser one, with polished flanks and sharply cut bevels.
Eighteen is the count, and they divide into three groups. Timekeeping proper covers the hours and minutes, a second time zone, a dead beat seconds hand and the tourbillon with its constant force device. The calendar group covers an annual calendar that knows the length of every month but February, a moon phase and a zodiac indication. The astronomical group is where the watch earns its name: sidereal time, which runs about four minutes a day ahead of civil time and is what astronomers use to find a star again, the equation of time, which is the running difference between the sun and the clock, and sunrise and sunset displays calculated for a given latitude. On top of all of that the watch strikes, sounding the hours, the quarters and the minutes on demand. Journe's constraint was that every one of these should be adjustable from the crown alone, without correctors set into the lugs or pushers on the band, and the mechanism that makes that possible is the part of the design that took the longest to resolve. The repeater is the part most owners talk about. Steel gives it a brighter and longer voice than gold would, and Journe has used the metal on every chiming watch he has made for exactly that reason rather than for any other. Hearing it is also the only way to experience most of the movement, since the striking work sits under the dial and is not visible from either side.
Journe's route to this watch runs through a pocket watch he made in 1987 for a collector of scientific instruments, which showed mean and sidereal time, the equation of time and a full calendar around a tourbillon. He treated that piece as unfinished business for thirty years. The Astronomic is not a scaled copy of it; the movement was drawn from nothing, hand wound, with two barrels to supply the energy that eighteen functions consume. Within the catalogue it sits above everything else, including the Sonnerie Souveraine, which held the position of most complicated Journe until 2019 and has fewer parts in it. It also does something the Sonnerie does not, which is to combine a striking watch with an astronomical one, two categories that historically stayed apart because each is difficult enough alone. Output is deliberately tiny and the watch is built to order rather than to stock, so the population grows by a handful a year and the earliest examples are already hard to find. It also changed what the collection looks like from outside. Before 2019 the house was understood as a maker of precise, restrained watches with one idea each, and the grand complication category belonged to other names. The Astronomic put Journe in that category without changing anything about how his watches look, which is a harder trick than adding complications to a dial.
This is not a watch bought for wearing daily, and Journe has never pretended otherwise. It is 44 mm of steel with two faces, and the second face is only useful if the watch comes off the wrist to be read. What it offers is the whole of one watchmaker's ambition in a single object, assembled at a rate of four or five a year by a house that makes fewer than a thousand watches in total. The steel case is the detail that separates a knowledgeable buyer from a casual one, since it looks like a step down and is in fact the reason the repeater sounds the way it does. Anyone considering one should expect a wait and should expect the conversation to be with the manufacture rather than with a shop. Condition and completeness matter less here than provenance and the original delivery record, because these watches are individually tracked. The other honest observation is that eighteen functions take time to learn, and an owner who never reads the instructions will use perhaps five of them. That is not an argument against the watch, but it is worth knowing before committing to it.
