Resetting the chronograph counters
If necessary, the chronograph counters (
5, 6, 7
) must be reset before starting timing. Proceed as
follows: pull the crown (
8
) out to position
II
; the chronograph seconds hand (
5
) will complete a
rotation of the dial (entering setting mode). Every time pusher (
A
) is pressed, a different hand
will be activated, and it can be returned to its start position by repeatedly pressing pusher (
B
).
When pusher (
B
) is held down, the hand rotation speed will increase.

Congratulations!
We congratulate you on choosing a chronograph from CERTINA
®
, a Swiss brand among the most highly renowned in the world. Meticulously designed, using
only the highest quality materials and components, it is protected against impacts, temperature variations, water, dust and also features the
DS
concept.
This user manual applies to CERTINA
®
quartz chronographs equipped with the PRECIDRIVE G10.962 BF GMT movement. For the settings and operation of your
PRECIDRIVE chronograph, please refer to the instructions below.
Your PRECIDRIVE chronograph allows you to time events lasting up to 12 hours, and offers you the following functions:
– Standard chronograph START–STOP function
– ADD function (partial times)
– SPLIT function (intermediate times)
To ensure that your chronograph operates with perfect precision for many years to come, we advise you to pay careful attention to the advice given in this
user manual.
The
DS
(Double Security) concept is characterised by:
– extreme impact resistance,
– an ultra-resistant sapphire crystal,
– a gasket inside the crown and a gasket around the winding stem guaranteeing the water resistance of the watch even when the crown is pulled out,
– a reinforced case back.
Settings
Models with screw-in crown
To ensure even better water resistance, some models are fitted with a screw-in crown (
8
). Before setting the time or date, you must first unscrew the crown
to position
IB
, before pulling it out to position
II
or
III
.
Important : After each operation, you must always screw the crown back in to ensure that your watch remains water-resistant.
You are advised not to operate the crown (8) underwater.
Setting the time
Pull the crown (
8
) out to position
III
; the seconds hand (
3
) will stop and the chronograph seconds hand (
5
)
will complete a rotation of the dial (entering setting mode). Turn the crown (
8
) clockwise or anticlockwise
to set the desired time, and then push it back into the rest position
I
. When the hour hand (
1
) passes the
12 o'clock position, you can see whether it is indicating midnight (the date will change) or midday (the
date will not change).
Advice for synchronising your watch
To synchronise the seconds hand (
3
) with an official time signal (radio/TV/Internet), pull the crown (
8
) out
to position
III
; the seconds hand (
3
) will stop. At the tone, push the crown (
8
) back into the rest position
I
.
Rapid date correction
Pull the crown (
8
) out to position
II
. The chronograph seconds hand (
5
) will complete a rotation of the dial (entering setting mode). Turn the crown (
8
)
anticlockwise until the desired date is displayed.
Tachymeter scale (depending on model)
The tachymeter scale enables you to measure the average speed of a moving object. Start timing by pressing pusher (
A
), and then stop by pressing pusher (
B
)
once a distance of 1 km has been reached. The chronograph seconds hand (
5
) will be pointing to the tachymeter scale, indicating the speed in km/h.
