In 1795, Breguet conceived the “Breget overcoil” spring, today still the reference in terms of balance springs. In 2006, Breguet introduced its first wristwatches with silicon balance spring and escapement. Today, the new Breguet silicon balance spring is featured in the Breguet Tradition 7047 model with tourbillon and fusee-and-chain transmission. Inspired by the design of the first tourbillon-equipped pocket watches devised by Breguet, a platinum version is now available fitted with a movement fashioned in an anthracite-toned metal alloy.
The fusee-and-chain transmission connected to the barrel ensures constant force for as long as the watch is running. A number of patents applications involve the large tourbillon resonator at one o’clock on the watch face, one for a titanium balance and three relating to Breguet silicon balance springs. A further patent was awarded for a power-reserve indicator positioned directly on the barrel.
