The impressive outcome of years of intensive research, Breguet’s CLASSIQUE GRANDE CO M P L I C A T I O N 5347 is equipped with twin rotating tourbillons actioned by a handwound mechanical movement to form an undisputed masterpiece of technology and design. With its caseband thinned down at the top, bottom and sides, the watch’s Ø-44 mm platinum case opens on a superbly decorated rotating dial plate featuring apertures for its pair of tourbillon carriages.
It contains the more than 570 parts and components painstakingly assembled by teams of Breguet master watchmakers. Working independently one from the other, the two tourbillons are coupled by means of differential gears and mounted on a rotating center plate effecting a complete revolution in twelve hours. The differentials transmit the mean rate of the two tourbillon regulators and the display of the time to the rotating center plate, allowing the simultaneous and tensionally equal rewinding of the twin barrels. The movement’s rate is therefore the mean rate of the two tourbillons, making its running rate twice as precise as a normal movement’s. The oscillators’ isochronism errors in the vertical positions are cancelled.
The current hour is shown via the bri dge connecting the two tourbillons, which doubles as an hour hand, while the minutes are indicated by a standard minute hand at center. The watch’s exceptionally meticulous finish includes engine -turning by hand, elegant Roman numerals, blued-steel Breguet hands, the movement’s decorated bridges and bars, circular - grained wheels and chamfered sinks, not to mention its many bevelled and polished parts.
The back of the movement holds further refinements; not least the view through the clear sapphire caseback of an engraved diagram of the solar system arrayed around the movement’s scintillating gears. Three patent applications have been filed to protect this timepiece’s unique features: original winding system, more than one regulating system and differential g earing. Its successful development stands as a salute to precision at its most exceptional. Its winding and time -setting mechanism is a two-part construction to allow proper centering of the crown on the case flank.
