Introduced in 2006, the Breguet Double Tourbillon 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.
Round, in 18K pink gold, with finely fluted caseband. Sapphire caseback. Diameter: 44 mm. Rounded horns welded to the case, screw pins securing the strap. Water-resistant to 30 meters.
Ring-shaped, forming a flange in 18K silvered gold. Individually numbered and signed BREGUET. Chapter ring with Roman numerals. Rose gilt open-tipped BREGUET minute hand. The hour hand is an extension of the bridge supporting the two tourbillon carriages. Manually engine-turned center plate featuring apertures for the two tourbillons and rotating in step with the hours.
Hand-wound mechanical movement with twin tourbillon regulators mounted on the manually engine-turned rotating center plate. The two regulators are coupled by a differential gear that combines the mean rate of the two movements. The tourbillons effect a complete revolution in 12 hours. Movement numbered and signed BREGUET. 50-hour power reserve. 16 ½ lines. 85 jewels. Cal. 588. BREGUET overcoil. Frequency 2.5 Hz. Monometallic BREGUET balance wheels with four gold regulating screws. Adjusted in 6 positions. The back of the movement bears a hand-engraved representation of the solar system, inspired by the 60-second rotation of the tourbillons on themselves and their rotation in tandem around a center axis over a 12-hour period.
