There is an important difference in meaning between the words \u201ceternal\u201d and \u201cperpetual\u201d. The first, which derives from the Latin aevum<\/em> \u2013 i.e. time \u2013 indicates something that has always been, still is and will be forever. The second, from the Latin per + petere<\/em> \u2013 i.e. to proceed relentlessly in one direction \u2013 indicates something with a beginning and that keeps happening. Like the days in the journey of humankind, those counted with a perpetual calendar on the wrist. Maybe with the new Quanti\u00e8me Perp\u00e9tuel by F.P. Journe<\/strong>.<\/p>\n\n\n\n

\"F.P.<\/a><\/figure>\n\n\n\n

The Quanti\u00e8me Perp\u00e9tuel has replaced the Octa Calendrier with annual calendar<\/strong> after entering the brand’s catalog as the tenth creation of the Octa collection. An industrial choice due to the manufacture\u2019s limited production capacity, which thus preserves the quality of its watches.<\/p>\n\n\n\n

FEW WORDS ON THE PERPETUAL CALENDAR<\/strong><\/strong><\/h4>\n\n\n\n

Both enthusiasts and, above all, watchmakers such as Fran\u00e7ois-Paul Journe love the perpetual calendar complication, which allows the latter to demonstrate all their genius. But it is also a complication that comes from far back in time, from the eighteenth century, when astronomical clocks gradually gave way to those that displayed the date and often also the moon phases, a legacy from their astronomical vocation.<\/p>\n\n\n\n

These watches had a calendar which required manual adjustment in months lasting less than 31 days. The challenge for the artisans of the time was first to devise a mechanism that would overcome this problem by automatically selecting the correct date, then to do the same with February 29th. That is, to create a system that recognized leap years, correctly marking February 29th and then moving on to March 1st. The basis of the perpetual calendar<\/strong>.<\/p>\n\n\n\n

The complication makes it possible to display the exact date automatically, taking into account the length of the months and the leap years cycle<\/strong>. It also displays the day, month and sometimes the moon phases. As recalled by F.P. Journe\u2019s team, this functionality requires the watch to have what they call a “mechanical memory” equal to 1461 days, the four years of the leap cycle<\/strong>.<\/p>\n\n\n\n

\"F.P.<\/a><\/figure>\n\n\n\n

This “memory” uses a small toothed planet wheel connected to the month\u2019s mechanism to<\/strong> perform a complete rotation over four years; during the fourth year, the mechanism displays February 29th before directly moving on to March 1st<\/strong>. Just as the moon moves around the earth, this planet wheel rotates on its own axis resting on a swivel wheel.<\/p>\n\n\n\n

And that’s not quite enough. Since the Gregorian calendar, on which the measurement of our time is conventionally based, rules that the year 2100 \u2013 as three centennials out of four \u2013 will not be a leap year, current perpetual calendars will need manual correction to move from February 28th to March 1st, 2100, skipping the 29th. Not bad: it’s a problem for posterity.<\/p>\n\n\n\n

QUANTI\u00c8ME PERP\u00c9TUEL \u2013 F.P. JOURNE\u2019S ANSWER<\/strong><\/strong><\/h4>\n\n\n\n

F.P. Journe could not resist the charm of such a complication, which he experienced not as a challenge but as an opportunity to test and further improve his watchmaking art. Opportunity that he fully grasped, if you look at the level of accuracy reached by the Quanti\u00e8me Perp\u00e9tuel, as you can see in our pictures, made possible thanks to the collaboration of GMT \u201cGreat Masters of Time\u201d<\/a>; partner of F.P. Journe since 2007. In 2014 it has been the first retailer in Europe to open an Espace F.P. Journe, a place dedicated to collectors and enthusiasts where you can see and touch the complete watch collection<\/strong>.<\/p>\n\n\n\n

\"F.P.<\/a><\/figure>\n\n\n\n

Compared to other perpetual calendars, albeit refined, F.P. Journe added two features to his Quanti\u00e8me Perp\u00e9tuel, the expression of two commandments for him: clarity and legibility. Thanks to a dial that makes all the information needed by the wearer immediately visible.<\/p>\n\n\n\n

THE DIAL\u2019S LEGIBILITY<\/strong><\/strong><\/h4>\n\n\n\n

The dial of the F.P. Journe Quanti\u00e8me Perp\u00e9tuel<\/strong> is rational and orderly, with large apertures to display the perpetual calendar\u2019s information: one window for the day of the week, one for the month, two for the tens and units of the large date<\/strong>, a feature common to the other F.P. Journe watches displaying the date.<\/p>\n\n\n\n

The date jump \u2013 a function that requires a lot of energy<\/strong>, consequently subtracted from the movement \u2013 is instantaneous. To overcome this problem, F.P. Journe has devised an ingenious system designed to accumulate energy and release it instantaneously when the date<\/strong>, day or month changes; and then slow it down at the end of its course.<\/p>\n\n\n\n

\"F.P.<\/a><\/figure>\n\n\n\n

In addition to the apertures for the date, months and days of the week, the perpetual calendar is completed by the four years indication placed in the center of the dial, under the hour and minute hands; the leap year is indicated by a red L<\/strong>, the other three years by the numbers 1, 2, 3 made of silver. The retrograde power reserve indication is located at 9 o’clock<\/strong>.<\/p>\n\n\n\n

The blue shade of the silver dial is stunning, enhanced by the guilloch\u00e9 work of the central part which contrasts with the smooth hour ring and the power reserve counter, with its concentric circles finish<\/strong>. The white chemin-de-fer<\/em> minute track recalls the background of the date windows, while the apertures and applied numerical indexes in white gold<\/strong> match the rhodium-plated steel hands<\/strong>.<\/p>\n\n\n\n

\"F.P.<\/a><\/figure>\n\n\n\n

CHILD\u2019S PLAY<\/strong><\/strong><\/h4>\n\n\n\n

We talked about F.P. Journe\u2019s two commandments featured on the dial of the Quanti\u00e8me Perp\u00e9tuel. Let\u2019s add a third one, which characterizes the whole watch: ease of use. Unlike many perpetual calendars, usually difficult to adjust, almost all corrections in the Quanti\u00e8me Perp\u00e9tuel by F.P. Journe can be made using the three-position crown<\/strong>.<\/p>\n\n\n\n

\"F.P.<\/a><\/figure>\n\n\n\n

To set the day and date, or just the date, click the crown into position 1 by rotating it in one direction or the other, depending on the setting you want. A further click in position 2 allows you to adjust the time. In position 0 it is possible to manually wind the Quanti\u00e8me Perp\u00e9tuel. A hidden corrector beneath the lug at 1 o\u2019clock is needed only for the rapid correction of the months<\/strong>.<\/p>\n\n\n\n

THE CASE AND THE MOVEMENT<\/strong><\/strong><\/h4>\n\n\n\n

The case, 40 or 42 mm depending on the wearer\u2019s preference, is in platinum<\/strong> and alternates a satin finish on the side and a polished finish on the lugs and bezel. Only 10.85 mm, its thinness and short lugs make the timepiece pleasantly wearable even on wrists that are not particularly large. And the case holds this watch\u2019s star feature: the automatic movement (whose development was based on the caliber 1300.3) in 18K rose gold, like that of all the precision chronometers produced by the brand<\/strong>.<\/p>\n\n\n\n

\"F.P.<\/a><\/figure>\n\n\n\n

Visible through the sapphire crystal caseback<\/strong>, the movement beats at 21,600 vibrations \/ hour and is only 5.90 mm thick. More than for the incredible technical solutions that animate the perpetual calendar, the caliber of the Quanti\u00e8me Perp\u00e9tuel by F.P. Journe catches the eye for its finishes, as excellent as the mechanics. The off-center rotor in 22K 5N gold<\/strong> (with its considerable specific weight which helps the movement to recharge faster) is decorated with a circular guilloch\u00e9 motif while the bridges, in 18K red gold, have a circular C\u00f4tes-de-Gen\u00e8ve finish<\/strong>.<\/p>\n\n\n\n

\"F.P.<\/a><\/figure>\n\n\n\n

Even the smallest parts of the caliber have been carefully refinished by F.P. Journe: the screw heads are polished and have chamfered slots, just as the steel components are hand-polished and chamfered. Automatic winding takes place through the unidirectional movement of the rotor, made possible by an autoblocant ball bearing system<\/strong>. <\/p>\n\n\n\n

NOT ONLY BLUE<\/strong><\/h4>\n\n\n\n

The blue Quanti\u00e8me Perp\u00e9tuel belongs to the Boutique Collection <\/strong>and, in addition to our shooting\u2019s star reference, it is also available with a five-row platinum bracelet or with a gold case and alligator strap, or a five-row gold bracelet. The reference with a whitened silver dial is part of the Classique Collection<\/strong>.<\/p>\n\n\n\n

In short, once you understand the difference between \u201ceternal\u201d and \u201cperpetual\u201d, wearing the Quanti\u00e8me Perp\u00e9tuel by F.P. Journe is a nice way to enjoy the passing of time. Of course, there would also be the adjective \u201cperennial\u201d but, as you can guess from the sound of the word, we will talk about this when talking about an annual calendar.
