F.P.Journe has created a warm-coloured dial that perfectly matches the 40 mm Platinum and 18K 6N Gold cases as well as the caramel alligator strap of the Chronomètre Souverain. THIS MODEL IS ALSO AVAILABLE WITH PLATINUM AND 18K 6N GOLD BRACELETS.
The dial colour is unique to F.P.Journe, a result of the company's well-tended independence, which ensures its creative freedom. It was developed by Journe's own dial makers, Les Cadraniers de Genève, in a process lasting several months. In essence, it is a combination of gold and ruthenium. But to get the colour just right required many adjustments to the formula.
The Chronomètre Souverain is a precision chronometer that was inspired by the Marine chronometers of the early 19th century. Constructed in the purest chronometric tradition, it has an extraflat movement that is 4 mm thick; its base plate and bridges are in 18K rose Gold. The two barrels of the homogeneous movement deliver a highly linear force to the escapement for over fifty-six hours. The escapement beats at a frequency of 21,600 vibrations per hour.
With its traditional yet unexpected look, the Chronomètre Souverain has become a model of reference. It is particularly slim, at only 8 mm thick. The small seconds subdial is at left at 7 o'clock, while the 56-hour power reserve indication is located on the right at 3 o'clock. Owning a Chronomètre Souverain is the ultimate luxury for those who are mindful of the time still to come, and intend to enjoy it thoroughly.
The Chronomètre Souverain received the Best Men's Watch Prize at the Geneva Grand Prix d'Horlogerie in 2005.
What is chronometry?
Consistency in the indication of time.
In the field of mechanical watches, the precision of a chronometer depends on numerous factors. It cannot hope to rival quartz, yet its worth undoubtedly lies in innovation, in horological mechanical poetry, and in research into mechanical subtleties, representing humble bricks that will find their place in the historical wall of horological science.
"Chronometry was invented by the 18th century English and French watchmakers, when their respective governments organised a competition that would reward the first watchmaker capable of making a timekeeper that could be carried on board a ship. Endowed with great precision, it was designed to calculate longitude. The conquest of the world's great oceans and vast uncharted territories was at stake!
In this quest for precision, a portable timekeeper is subject to several natural phenomena liable to be detrimental to its initial rating.
- Thermal variations: the balance and spring assembly is sensitive to changes in temperature, leading to gains when it is cold and losses when it is warm.
- Movements: especially those of the wrist for wristwatches, resulting in abrupt accelerations or decelerations of the balance.
- Geographical situation: two factors are perceptible: first of all latitude, and secondly altitude. In both cases, the gravitational force changes with the friction of the balance pivots, causing losses when moving away from the centre of the earth or gains when drawing closer to it.
- Deterioration of the lubricants: the oils lubricating the escapement harden with age, which in time will cause the watch to gain.
In these four cases, the real precision is not affected; it is only the gauging that has changed! As fas far as F.P.Journe chronometers are concerned, they are adjusted in our workshops in Geneva before being sold throughout the world. Depending on the geographical location of the purchasers, a difference of several seconds may be observed. In each part of the globe, a difference in rating compared with that of Geneva is normal: the gauging of the chronometers changes, but not its precision. Witness the fact that when a timepiece gains two seconds per days and maintains the same gain every day, this actually confirms its extreme precision.
When navigating in the past, captains used to take account of the deviation of their chronometer and integrate it into their calculations to determine the ship's position. If the chronometer showed a deviation corresponding to a one-second gain per day, all that was needed after 30 days was to subtract 30 seconds in order to know the exact time, and so on for each day…"
