The Breguet La Tradition Grand Complication is a superlative model in the firm's repertoire. Breguet impressively showcases classic and new technologies with a 50 hour fusee and chain power reserve, and a one minute tourbillon with titanium bridge and silicon overcoil hairspring. The fusee chain is a traditional technique that has been used in pocket watches since the 19th century. When wound, the conical shape fusee barrel is wrapped with a miniature chain, which then creates a constant and smooth power output from the barrel as energy is released. The famous Breguet overcoil hairspring has also been updated with innovative silicon material. As silicon is devoid of the malleability of metal, it required a complete rethinking of the production process to form a bend rising up from the coil.
To protect and showcase this tour de force complication, the present 7047 is protected with a heavily domed sapphire crystal, case forged in yellow gold. The watch is a true combination of Breguet's commitment to both tradition and the future.
