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.

BCorrect the hand position:

Short press: step-by-step

Long press: rapid continuous rotation

Resetting the chronograph counters

If necessary, the chronograph counters (5, 6, 7 and 8) must be reset before starting timing. Proceed as follows: pull the crown (9) out to position II; the

counter hands (5, 6, 7 and 8) will complete a rotation of the dial (entering setting mode). Every time pusher (A) is pressed, a hand will complete a rotation

of the dial (active hand), and can be returned to its start point by repeatedly pressing pusher (B).

Simple timing

The "simple timing" function enables you to measure individual events.

The SPLIT SECOND function enables you to stop the

hand(8) to read a split time without interrupting the timing.

When you restart, the chronograph hands "catch up" to the

ongoing elapsed time.

Technical information

Winding

Quartz watches do not need to be wound.

PRECIDRIVE

PRECIDRIVE quartz chronographs, from CERTINA®, can boast not only the incomparable precision of quartz, but also their temperature variation compensated

(thermo-compensated) rate, making them insensitive to moisture. This enables them to achieve a precision of around +/-10 seconds per year (under normal

conditions of use).

Automatic calibration

The POWERDRIVE motors used to drive the hands ensure extremely precise and rapid movements. To ensure that they are working correctly, an automatic

calibration is performed once an hour on both the central counter hands (7and 8):

– One-step forward / backward movement

– A complete dial rotation (alternating between the two hands)

These visible movements are part of the normal operation of the chronograph.

EOL (End of Life) function

When the seconds hand (3) is jumping every 4 seconds, your chronograph is telling you that the battery has reached its end of life, and will soon need to be

replaced.

Care and maintenance

We would advise you to clean your chronograph regularly (except for the leather strap) using a soft cloth and lukewarm soapy water. After immersion in salt

water, rinse it in fresh water and leave it to dry completely.

Do not leave it anywhere subjected to high variations in temperature or humidity, direct sunlight or strong magnetic ﬁelds.

We would advise you to have your watch inspected every 3 to 4 years by an approved CERTINA®representative or retailer. To enjoy impeccable maintenance

service and ensure the guarantee remains valid, always consult an approved CERTINA®representative or retailer.

If you plan not to wear your chronograph for several weeks or months, we would advise you to store it with the crown (9) pulled out to position III. This cuts

the electrical power supply to the motor, thereby extending battery life considerably.

Replacing the battery

The autonomy of a PRECIDRIVE chronograph from CERTINA®is generally more than 2 years in continuous use. Once the battery has been drained, it must be

replaced without delay by an approved CERTINA®representative or retailer.

Battery type: silver oxide and zinc button cell, 1.55 V, No. 394, SR 936 SW.
