Chronograph function
Press the Start/Stop push-button (12) to start the
chronograph. Press the Start/Stop push-button (12)
again to stop it. The chronograph will resume if the
Start/Stop push-button (12) is pressed again (added
times), or the three chronograph hands (9, 10 and 11)
will return to zero if push-button (13) is pressed.
Notes
The 12 hour counter (11) has an area with alternat-
ing colours (black/white) indicating every half hour,
matching the outer numerals (0 to 30 minutes) and
inner numerals (30 to 60 minutes) of the same colour
on the 30 minute counter (10).
Depending on the model you have chosen, the colours
of the 12 hour counter area (11) may vary (e.g. white/
red, black/red, white/yellow, etc.), but they always
match the numerals on the 30 minute counter.

Start the chronograph and stop it once a distance
of 1 km has been covered by pressing the Start/Stop
push-button (9). The chronograph hand will be point-
ing to a numeral on the tachymeter scale (8), indicating
the speed in km/h.
