YEMA RALLYGRAF MECA - QUARTZ WATCHES

POSITION A DATE SETTING
To adjust the date, pull the crown to POSITION A. Then simply turn it clockwise until the desired date
appears in the window.
IMPORTANT: Do not make date adjustments when the time on the watch reads between the hours
of 9:00pm and 3:00am. The reason is that although a date makes its changeover close to midnight,
the gears that make that change happen to engage quite a bit earlier. It takes extra time to disengage
completely in the aftermath.

POSITION B TIME SETTING
In order to adjust the time, pull out the crown to the last notch. Then turn it in either direction until the
hands indicate the correct time.
If the crown is pulled to POSITION B while the chronograph is started, the chronograph hands will
continue to move. This is not a malfunction.

CHRONOGRAPH
FUNCTIONS

PUSHER A START/STOP CHRONOGRAPH
Press button A to start the chronograph. The chronograph hands will start moving.
Press button A again to stop the chronograph. The chronograph hands stop to indicate the elapsed
time.
The center 1/5 chronograph second hand displays the elapsed seconds while the 9 O’clock sub-register
shows the elapsed minutes (maximum 60 minutes)
PUSHER B RESET CHRONOGRAPH
Press button B to reset the chronograph. All the chronograph hands will be reset to “0” position.

TACHYMETER
FUNCTION

The bezel on your watch has a tachymeter function used to measure a speed or a flow rate using the
chronograph function. Select the desired unit of measurement (metre, kilometre, mile, litre, etc.],
activate the chronograph and stop it when the desired unit is reached. The centre seconds hand
indicates the number of units per hour on the tachymeter scale.
In order to ensure the precision of the tachymeter, the unit of measurement must be exactly reached.
In addition, the time of measurement should not exceed 1 minute and should not be less than 9
seconds.
