The Double-face flying tourbillon offers world time with indexable second-time zone, moon phase, and five days’ power reserve
July 8, 2020: Watchmaking excellence is ingrained into the makers of Bovet. Its new new Récital 26 Brainstorm Chapter Two sticks to the DNA, and in fact, surpasses in offering collectors with a piece that is so magnificent that it is staggering.
The Brainstorm Chapter Two is the second timepiece in the Bovet collection to be fitted with a sapphire crystal case in the emblematic writing case with an asymmetrical profile. The slope of its bezel allows the collector to explore new display mechanisms that guarantee intuitive and increased readability. Concentric rollers, rotating domes, and three-dimensional needles were used to express time in new ways. The protected design of the writing case opens up new horizons in terms of the very architecture of the movements, by optimizing the volume which simultaneously increases the functionalities offered, the chronometry, the reliability, and the readability.
The middle and the glass form only one single element, 47.80 in diameter, which meticulously respects the original design of the cases in the collection. The back is made up of a bezel and four horns machined from grade 5 titanium. The sapphire crystal case opens generously to display the movement which has many secrets to reveal. To optimize transparency and ergonomics, the watchmakers decided to fix the movement at the bottom rather than inside the middle, as is usually the case.
The caliber for Brainstorm Chapter Two is entirely manufactured in the Bovet workshops. Absolute control of energy guarantees an autonomy greater than five days of power reserve by the use of a single barrel, which maintains the oscillations of the regulating structure at a frequency which has been increased to the frequency of 21,600 v/h for spectacular chronometry enhanced by the patented double-sided flying tourbillon.
A dome dial, available in a choice of blue or green translucent quartz or blue aventurine glass, displays the hours and minutes of local time in the upper part of the case. The seconds are read by an index fixed on the tourbillon itself, placed at 6 o'clock which makes a complete revolution, in 60 seconds. The dome, located at 3 o'clock, displays a second time zone, according to the construction, specifically developed for this timepiece and subject to a patent. The names of 24 cities representing the 24 time zones are printed on the rotating part of the dome which makes a complete revolution, by scanning the 24-hour graduation of the base ring. A three-dimensional V-shaped needle allows the collector to select the displayed time zone.
In addition to a second time zone display, this new display also offers the world time function, which allows the time in each of the 24 time zones to be read simultaneously.
In perfect symmetry, the moon phase indicator is positioned at 9 o'clock and is also displayed by a rotating dome. The surface of the lunar ground is hand-engraved before a luminescent material is applied, also, by hand. The two circular windows which overhang the dome make it possible to read the age of the moon according to the specific orientation of its crescent, whether one is in the northern hemisphere or the southern hemisphere of the earth. The precision mechanism that drives this dome gives it an accuracy that requires a correction of one day every 127 years!
The domes of the second time zone and the moon phase rotate by the patented mechanism of the radial guidance system. Three rollers, in rubies adjustable by a micrometric screw, are arranged on the circumference of each dome. They ensure centering and the rotation minimizes friction and therefore, freeing the interior volume of the globes, which increases the chronometry and the power reserve of the timepiece.
Polished pillars, translucent gems, and delicately satin steels contrast with dazzling elegance. At the back of the timepiece, the bridges are perforated and engraved with a delicacy.
This masterpiece, available for approximately $379,000, is limited to 60 movements only. They will be distributed among the 47.8mm-diameter sapphire case, limited to 30 timepieces, with a choice of blue quartz, green quartz, or blue aventurine glass dial, by respective limited editions of 10 timepieces. As usual, collectors may bespoke their timepieces and thereby acquire unique pieces. Regardless, no more than 10 of any single style made from these 60 movements will be crafted.
