Congratulations!
We congratulate you on choosing a PRECIDRIVE chronograph from CERTINA
®
, one of the most highly renowned Swiss brands in the world. Meticulously
designed, using only the highest quality materials and components, your chronograph is protected against shock loads, temperature variations, water, dust
and also benefits from the DS concept.
This user manual applies to CERTINA
®
quartz chronographs equipped with the PRECIDRIVE 251.294 KP movement. For the settings and operation of your
PRECIDRIVE chronograph, please refer to the instructions below.
Your PRECIDRIVE chronograph enables 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 SECOND function (split times)
– FLYBACK function (restart the chrono without resetting)
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:
– an extreme shock resistance to scratches and impact,
– 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 (
9
). Before setting the time or date, you must first unscrew the crown (
9
)
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 (9) underwater.
Setting the time
Pull the crown (
9
) out to position
III
; the seconds hand (
3
) will stop, and the chronograph counter hands
(
5, 6, 7
and
8
) will complete a rotation of the dial (entering setting mode). Turn the crown (
9
) 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 (
4
) will change) or
midday (the date (
4
) will not change).
Note: STOP SECONDS
with
crown
(
9
) in position
III
.
Advice for synchronising your watch
To synchronise the seconds hand (
3
) with an official time signal (radio/TV/Internet), pull the crown (
9
) out
to position
III
; the seconds hand (
3
) will stop. At the tone, push the crown (
9
) back into the rest position
I
.
Changing time zone or switching between summer time / winter time
Pull the crown (
9
) out to position
II
; the chronograph counter hands (
5, 6, 7
and
8
) will complete a rotation of the dial (entering setting mode).
Turn the crown (
9
) clockwise or anticlockwise to set the desired time.
Rapid date correction
Pull the crown (
9
) out to position
II
. The chronograph counter hands (
5, 6, 7
and
8
) will complete a rotation of the dial (entering setting mode).
Turn the crown (
9
) clockwise or anticlockwise until the desired date is displayed. During this operation, only the hour hand rotates.
When the hands pass midnight, the date (
4
) will change. To finish, push the crown (
9
) back into the rest position
I
.
Tachymeter (depending on model)
The tachymeter enables you to measure the average speed of a moving object. Start timing by pressing pusher (
A
), and then stop by pressing pusher (
A
) once
a distance of 1 km has been reached. The superimposed chronograph seconds hands (
7
) and (
8
) will be pointing to the tachymeter scale (
D
), indicating the
speed in km/h.
