On 26th June 1801, Abraham-Louis Breguet filed a patent for the creation of the first tourbillon. To mark this date, Swiss luxury watch brand Breguet unveils a special timepiece from the Tradition collection.
Tourbillon is one of the most greatly appreciated horological mechanisms as it reveals the heart of the watch. The new Breguet Tradition Tourbillon 7047 watch in platinum houses the fusée-chain tourbillon transmission mechanism for optimising the regularity of the watch’s operation by guaranteeing its constant torque, whatever its winding level is.
When the barrel is fully wound, it delivers its maximum force. The chain then acts on the top of the fusée and therefore on its smallest circumference. As the chain unwinds, its torque decreases yet acts in parallel on the widest part of the fusée – its base – thus ensuring the constant force of the energy is delivered.
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 new Tourbillon 7047 boasts the “Clous de Paris” guilloché pattern on its off-centre gold dial, the traditional Roman numerals and the open-tipped hands. Like the watches that inspired it, its dial is secured by three screws.
This 41 mm platinum watch houses the 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.
The balance of the Tradition Tourbillon 7047 oscillates at a frequency of 2.5 Hz. This movement provides a 50-hour power reserve.
The new Tradition Tourbillon 7047 watch is fitted with a midnight blue alligator leather strap secured by a triple-blade platinum folding clasp.
