The Tradition 7057 puts the fusée-and-chain transmission on the dial side, so you watch constant torque being maintained in real time. Breguet revived this 18th-century regulating device not as a heritage gesture but as a genuine engineering choice, and the 7057 in white gold is the clearest expression of that intent. At 40.8mm it wears larger than it looks on paper because most of the dial is movement.
Breguet introduced the Tradition line in 2005 as a deliberate inversion of conventional watchmaking: rather than hiding the movement behind a dial, the caliber is mounted on the front plate and displayed openly. The 7057 variant added the fusée-and-chain complication, which Abraham-Louis Breguet himself used to counter the uneven torque output of a mainspring as it winds down. Manufacture Breguet revived the technique in modern production as a credible mechanical argument, not decoration.
The white gold 7057BB/G9/9W6 has been in continuous production since 2012, which is a longer run than most complicated pieces at this price level, and it reflects genuine collector demand rather than a limited-edition marketing cycle.
The fusée-and-chain is the single most fragile element in this watch. The chain is made of roughly 550 individual parts and requires a specialist trained specifically on this complication for any service touching the remontoir side. Generic independent watchmakers should not attempt it.
The skeletonized architecture also means the movement accumulates dust and debris faster than a closed-caliber watch, so service intervals should be treated as a ceiling, not a suggestion. The white gold case shows contact marks around the crown and lugs more readily than a steel or yellow gold piece, and Breguet polishing is expensive. Finally, the 569 manual-wind has no power reserve indicator, so you will occasionally let it run down without realizing it, which on a fusée movement is a poor habit.
