Breguet 5837 Instrucciones De Uso página 10

The chronograph mechanism has its
roots in the "chronomètre à doubles
secondes" or observation chronome-
ter, which our founder developed in
1820. This historic instrument
anticipated the modern chrono-
graph.
The introduction of silicon
With the introduction of various
critical mechanical movement parts
in silicon, Montres Breguet has once
again achieved a major break-
through in horological technology.
The planet's second most common
substance after oxygen, silicon is
impervious to magnetic attraction
and influence and, more important
still, 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. opportuni-
ties to turn out new and complex
shapes.
