To mark the date of the creation of the Tourbillon by Abraham-Louis Breguet, the brand unveiled its latest model from the Tradition collection, a timepiece featuring strong colours highlighting what has remained, from past to present, – one of the most fascinating horological complications of all times.
The fusée-chain tourbillon mechanism appears sprinkled with touches of blue. Various treatments have been used on all the components in order to achieve visual uniformity: the tourbillon carriage and the dial are covered with blue coatings, while the chain links are thermally blued. This new feature reflects the aesthetics of the Tradition Quantième Rétrograde 7597 launched in May and elegantly plays with blue and slate grey contrasts.
The Tourbillon stemmed from a necessity keenly felt in the 18th century: namely, to overcome the lack of accuracy caused by the vertical position of pocket watches placed in gentlemen’s waistcoats or jackets. The challenge was taken up by Abraham-Louis Breguet, who on 26 June 1801 filed a patent for the creation of the first tourbillon. Ever since, this complication has remained one of the most greatly appreciated by devotees of fine watchmaking, since it reveals the heart of the watch.
The fusée-chain tourbillon transmission device housed in the new Tourbillon 7047 serves to optimise the regularity of the watch's operation by guaranteeing its constant torque, whatever its winding level is.
At the heart of its 41 mm platinum case beats Calibre 569, a rhodium-plated hand-wound movement housing 542 components. It is equipped with an inverted in-line lever escapement featuring horns made of silicon, as too is the Breguet balance-spring. This material has many properties, since in addition to being resistant to corrosion and wear, it is insensitive to the influence of magnetic fields and improves the chronometry (timekeeping precision) of the timepiece. Finally, the balance of the Tradition Tourbillon 7047 oscillates at a frequency of 2.5 Hz and has a 50-hour power reserve. Watch the video here :
