Breguet’s first and only series-made mechanical chronograph with a frequency of 72,000 vibrations per hour
Breguet is introducing a contemporary, technically updated
reinterpretation of that legendary chronograph supplied to the French
Naval air arm, the Type XXII design. Its stainless steel case, 44 mm
across, houses a Breguet chronograph movement with silicon escapement
and flat balance spring whose frequency has been raised to 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. An extra hand at
centre counts the minutes by adding together the 30-second spans. The
minutes graduation in the form of dashes – one red and the other white –
situated on the flange, combined with the numbered seconds graduation
also appearing in red and white, serves to establish whether the
chronograph counter is in its first (red sectors) or second (white
sectors) 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. A two-position crown resets the second
time-zone indicator by moving the hour hand at centre without affecting
the minute hand. With the crown in that position, the date calendar
obeys the time of the main time-zone displayed at centre. A 24-hour
night-and-day indicator at 3 o’clock tells the wearer whether it is
daytime or nighttime in the area covered by the second time-zone. At
nine o’clock, a subdial showing the running seconds making full
rotations in 30 seconds completes this truly exceptional timepiece. The
chronograph’s black dial contrasts crisply with the flyback indications
in red. The model comes fitted with an integrated veal strap.see more replica Breitling orologi and replica Burberry
