www.worldwatchweb.com - After four years of service in various watch movements, Breguet can report satisfactory results with flat silicon balance springs. The next step was to turn out silicon balance springs featuring the celebrated “Breguet” terminal curve. Actually putting a curve into a sliver of silicon represented no mean exploit in the world of watchmaking.
The springs are usually cut from flat wafers and remain uniformly thin strips. Getting silicon, devoid of the malleability of metal, to form a bend rising up from the coil required a complete rethinking of the production process, a technical challenge brilliantly mastered by Breguet technicians. The Breguet silicon balance spring will now be adding its specific advantages to silicon's on all Breguet movements, whatever their basic configuration.
