ts stainless steel case, 44 mm across, houses a Breguet chronograph movement with silicon escapement and flat balance spring whose
frequency has been raised to 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.
An extra hand at center counts the minutes by adding together the 30-second spans. At 12 o’clock, a rectangular aperture in the dial displays a retrograding pointer that indicates whether the chronograph seconds hand is completing its first or its second 30-second revolution.
The Breguet Type XXII chronograph naturally features a flyback function, allowing the totaliser to be returned to zero and instantly restarted in one and the same operation. Furthermore, the dial includes a second time-zone indicator along with an aperture for a date calendar.
