In-Depth The F. P. Journe Astronomic Souveraine

In-Depth The F. P. Journe Astronomic Souveraine

The F. P. Journe Astronomic Souverain was initially presented last July, as a unique piece for Only Watch. The unique piece, named the Astronomic Blue, has a tantalum case and blue dial, and it was a reverberating accomplishment at the sale, in the end hammering for CHF 1.8 million . There were a few articulations of shock, when F. P. Journe, not long after the sale, declared that the watch would go into creation, with an alternate dial, and in a steel case; the declaration was made on November 14th, in Tokyo. However, the underlying public statement from July 1 for the model, obviously noticed that the model would be followed by a creation model, yet one made in little numbers each year; F. P. Journe commented to a limited extent, “However the idea of model suggests there will be a completed piece. That part will have its spot among the assortment on the day following the Only Watch deal – 10 November. The Astronomic Blue will clear a path for the Astronomic.”

The essential plan of the watch, as per Journe, returns to a cosmic pocket watch, which he created for “a gatherer of logical instruments,” in 1987. That watch showed mean time and sidereal time, the equation of time, a full schedule, and the power hold. Absolutely, the two watches share a great arrangement for all intents and purpose – the pocket watch has the same double dial configuration as the Astronomic Souverain, however those familiar with F. P. Journe’s work will perceive that Journe has exploited the versatility of this plan in his reverberation watches as well.

This kind of configuration naturally fits quite a few combinations of two unique sorts of time. George Daniels utilized it to great impact in his Space Traveler watches and Daniels thus, owed an obligation to Breguet, whom he appreciated for the latter’s capacity to create complicated watches which, in spite of their mechanical complexity, and the amount of information passed on, still figured out how to achieve an extremely uncommon sort of class as well.

This specific variety of polish in complicated watches has for the vast majority of his profession, been quite possibly the most reliable characteristics of F. P. Journe watches. Exceptionally complicated watches have verifiably would in general be, precisely as you would expect, on the monstrous side – the Patek Philippe Henry Graves Supercomplication, for example, is 70mm in diameter and weighs over a pound, yet it contains chiming complications which it is hard to put on a careful nutritional plan: a grande et modest sonnerie, and minute repeater. However even on account of these two complications F. P. Journe has figured out how to fit them into an uncommonly thin and really exquisite case – the Sonnerie Souverain is at 42mm x 12.5mm somewhat huge in comparison to other complicated watches from Journe, yet it is surprisingly flat for such a chiming watch, and to get a grande et modest sonnerie with minute repeater into such a relatively little space, various technical innovations were required – there were a sum of 10 patents awarded to the watch.

A Ringing Success: The Sonnerie Souverain

The Sonnerie Souverain is quite possibly the most noteworthy complicated watches from F. P. Journe, and it has various striking technical innovations. To discover more, check out HODINKEE organizer Ben Clymer’s 2015 In Depth take a gander at the watch, and how it came about.

Journe’s affection for cosmic complications returns significantly farther than the 1987 pocket watch – perhaps the soonest project, at the age of 22, was to create a planetarium mechanism for Asprey in London, which was completed in 1979. The planetarium is regulated by a pendulum, and shows the developments of Mercury, Venus, the Earth around the Sun, just as the circle of the Moon around the Earth. 

Journe for much of his expert life has been famous for chronometrically arranged complications – he has been an excited experimenter with the tourbillon, the train remontoir (which he uses to power his deadbeat seconds complications) and obviously, his reverberation watches, which depend on the same standard as the reverberation watches made by Breguet, and in which the adjusts are mechanically coupled constantly pulling power set on the development plate by the equilibrium spring (a power so little that Breguet himself couldn’t at first accept the impact was genuine, yet which does indeed, bring about the two adjusts coming into reverberation). The new Astronomic Souveraine, however, is a re-visitation of the fascination Journe showed in his childhood, with the developments of grand bodies, and with time in accordance with the movement of such bodies.

Diagram of the dial of the Astronomic Blue; the Astronomic Souveraine has an indistinguishable configuration.

Most of the information conveyed is shown on the facade of the watch, and in fact, it is an astoundingly precise and insightfully coordinated showcase. The dial on the left shows sidereal time, or “star” time, which depends on the rotation of the Earth, relative to the fixed stars rather than to the Sun. Sidereal time gains around four minutes out of each day compared to common time; the hours of the latter is shown in the dial on the right, alongside the ideal opportunity briefly time region of the wearer’s choosing. 

The moonphase is shown in a gap on the lower right, which is adjusted by a comparative gap for the running seconds on the left. Evenness is improved by the arrangement of the power save at 6:00, and the dawn/dusk opening, which is decently precisely between eleven and one o’clock on the external edge of the principle dial – or I guess one should say five minutes before the hour, and five minutes after, as the numbers on the border of the dial are important for a minutes track (which, technically, makes this a regulator watch, at least to the extent common time is concerned).

The caseback of the Only Watch model, in tantalum.

The back of the watch, shows a few key development components, including the train remontoir, the 60 second tourbillon, the two jewels for the two origin barrels, and the equation of time. The latter is the contrast between mean sun oriented time, and real sunlight based time, the distinction can be generally give or take fifteen minutes at various focuses during the year. Knowing the equation of time was once helpful for setting tickers by a sundial, as you could essentially add or deduct the equation for the afternoon, from the time shown by the sundial. The yearly schedule shows the date, and too, the situation of the Sun in the Zodiac as it advances through them over the span of a year.

The day/night, dawn/dusk show of the Astronomic Souveraine.

The dawn/dusk complication is a somewhat surprising one. For the most part in watches with such a complication, the hour of dawn and season of nightfall are shown on two separate subdials. On uncommon events, in certain clocks and watches, the area configuration utilized by Journe in the Astronomic Souverain is utilized all things considered; it comprises of two moveable shades, which increment or diminishing the obvious circular segment which the Sun crosses, contingent upon the season. As of late, this framework was utilized by Dr. Ludwig Oechslin in the Ochs und Junior Day/Night , and Patek Philippe utilized it for the Star Caliber 2000 pocket watch (I’ve seen it utilized in old longcase tickers also). While it doesn’t disclose to you the specific season of nightfall or dawn this can generally be dictated by taking note of the time that the Sun shows up from behind the screen leaf on the left, and vanishes behind the leaf on the right, and the situation has the benefit of allowing you to see the amount of sunlight left also. You can likewise decide (once more, approximately) the hour of genuine sun oriented early afternoon, by taking note of when the Sun is at the highest point of the arc.

The caseback of the steel Astronomic Souveraine.

The view through the caseback of the Astronomic Souveraine is where, quite conceivably, there is the greatest contrast between the model and the creation watch. Where the steelwork and development plates and scaffolds in the model were left incomplete, in the creation model the full scope of completing techniques characteristic of very good quality watchmaking are available. While Journe has never been known basically for very fine completing per se, the type 1619 in 18k rose gold, is as magnificently turned out a mechanism as any Journe aficionado could trust and in its fundamental design, and the difference of cleaned steel with gold (which again, reviews the most amazing aspect English watchmaking, including the work of Dr. Daniels, and obviously the work of Breguet himself) it is a wonderful demonstration of exactly how enchanting perfectly created machinery can be.

Of course one final critical distinction between the Astronomic Blue for Only Watch, and the Astronomic Souveraine in steel, is the value; the Blue hammered for a record CHF 1.8 million , while the Astronomic Souveraine will be evaluated at CHF 889,000.
