Type XXII 3880 ST – Exceptional movement 10 Hertz!2010.06.21
Breguet chronograph Type XXII with its new movement and a silicon escapement and flat balance spring reaches a fantastic frequency of 10 Hertz (i.e. 72,000 vibrations per hour), endowing the movement with exceptional regulating power, its chronograph seconds hand effecting a complete rotation in 30 seconds.
The timepiece’s start function and readout are thus twice as precise. At the heart of this technical exploit is the use of silicon, resulting in more lightweight mobile components and the avoidance of the lubrication problems generated by high frequencies.
