Chronograph function
Your watch comes with a chronograph function (stop function). This enables you to mea-
sure 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. The chronograph is operated by means of buttons “A” and
“B”. Shortterm measurements start when button “A” is pressed once. Pressing this button
again stops the measurement. The shortterm measurement is resumed by pressing but-
ton “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, 37 seconds.
