Breguet Classique Grande Complication 5347 Double Tourbillon, in Pink Gold
Introduced in 2006, the Breguet Double Tourbillon watch houses a hand-wound movement fitted with a pair of tourbillon regulators rotating on the hour axis. An aesthetic as well as a technical masterpiece, the watch features today a pink gold case measuring 44 mm in diameter and housing over 570 components.
Working independently from one another, two tourbillons are coupled by means of differential gears and mounted on a rotating centre plate effecting a complete revolution in twelve hours. The differential device conveys the two tourbillons’ mean rate to the rotating centre plate and to the time-display mechanism.
The rate of the watch is thus the mean rate of the two tourbillons, making its movement twice as precise as a normal one. The hour is shown by the bridge connecting the tourbillon regulators doubling as a watch hand, while the minutes are indicated by a standard hand at centre.
Impeccable finish and spectacular new engraving work on the back of the movement further underscore this exceptional timepiece’s appeal. A manually engine-turned mainplate, a chapter ring inscribed with Roman numerals, pink gilt Breguet hands, a movement with decorated bridges and bars and other parts beveled and polished further testify to an exceptionally handsome design of unrivalled beauty and refinement.
