FUNCTIONS
J12 Chronograph
The Chronograph can be used to measure time or record several periods of time, thanks to the
central arrow shaped second hand H and the counters I and J, which display the elapsed
minutes and hours respectively. The CHANEL Chronograph movement has a COSC certificate
(Swiss Official Chronometer Control). The COSC certificate is specific to each watch and is
attached to theguaranteecard.
a)To start the Chronograph, press the button F: The 1st press triggers the time measurement. A 2nd
stops it and a 3rd restartsit.Thismakes it possible to record several timeintervalsat different times.
b) To reset theChronograph, press thebuttonG. Thecentral arrow shaped second hand H
returnsto itsinitialposition (numeral12)as do thesmall hands on counters I and J.

Chronograph Function
a)To start the Chronograph, unscrew then press button F: this first press starts the measurement of
time.Pressing again stops it and pressing a thirdtime,restartsthemeasurement.Thisallows several
measurementsto be accumulated at differentintervals.
b) ToresettheChronograph to zero, unscrew thenpress buttonG. Thecentralsecond hand H
willreturnto itsstartingposition (numeral12), as willdo thehand on counter I.
Tachymetric Function
The Tachymetric function enables to measure the speed of an object moving over a known
distance. The base length is indicated on the scale J.The speed per hour readings, indicated by
thescale, are based on an observational distance of 1,000 metres.
Theuser starts thechronograph (buttonF) when thevehicle crosses thestarting markerand
stops itwhen itpasses theend marker(butttonF).The position of thechronograph second hand
on thetachymetricscale corresponds to theaverage speed inkm/h.
E.g.Ifittakes 40 seconds to cover 1,000 m,theaverage speed is 90 km/h.
