Using the chronograph to measure time
Your watch comes with a chronograph function (stop function). this enables you to
measure and record periods of up to 11 hours, 59 minutes and 59 seconds. the central
stop-second indicator and the small hour and minute hands are used for measuring
time with the chronograph function. tthe chronograph is operated by means of buttons a
and b. the measurement starts when button a is pressed once. Pressing this button again
stops the measurement. the measurement is resumed by pressing button a once more.
this allows you to add up and record the cumulative time. button b resets the hands of the
chronograph to zero. Please see the diagram for an example of stopped time readings:
1 hour, 37 minutes, 36 seconds.
