Chronograph function
The timepiece features a chronograph mechanism that allows measurement of intervals from 1/1000th of a second
to 15 minutes. For this purpose, it uses a 1/1000th counter hand (G), 1/100th chronograph direct-drive seconds
hand (D), a seconds-counter hand (E) and a minutes-counter hand (F). It is a monopusher chronograph, i.e. the start,
stop and zero-reset functions are activated as you repeatedly press the monopusher (P1).
P1: a) Starting the chronograph
Check that the chronograph function has sufficient autonomy via the power reserve display (H).
Press the monopusher to set the chronograph function in motion. The direct-drive seconds hand (D), seconds-
counter hand (E), minutes-counter hand (F) and power-reserve counter hand (H) are working. The 1/1000th
counter hand (G) remains neutral until the chronograph is definitively stopped, at which point it will be
possible to read the 1/1000th of a second.
b) Stopping the chronograph
Press the monopusher (P1) again to stop the chronograph function. The time elapsed can be read. Begin by
first reading the minutes-counter hand (F), then the seconds-counter hand (E) and the 1/100th hand (D), and
finally the 1/1000th counter hand (G).
c) Resetting the chronograph to zero
After you have completed the measurement, press the monopusher (P1) a third time to reset the 1/1000th
counter hand (G), the chronograph direct-drive seconds hand (D), the seconds-counter hand (E) and the
minutes-counter hand (F) to zero.
