Introduced in 2006, reference 5197 is Breguet's first model using silicon for the anchor, the hairspring and the escape wheel, another major breakthrough in horological technology.
The planet's second most common substance after oxygen, silicon is resistant to magnetic attraction and influence and, even more important, highly resistant to corrosion and wear. Lighter and harder than steel, it reduces inertia, requires no lubricant and provides far greater geometric freedom, i.e. opportunities to turn out new and complex shapes.
