Congratulations

We congratulate you on choosing a CERTINA

®

 watch. Meticulously 

designed, using only high-quality materials and components, your watch 
is protected against shocks and impacts, variations in temperature, water 
and dust and also benefits from the 

DS

 concept.

To ensure the operating precision of your watch for many years to come, 
we advise you to pay very careful attention to the advice provided 
hereafter.
This user’s manual applies to 

all CERTINA

®

 quartz, quartz solar 

or autoquartz watches

. Please refer to the explanations relating 

specifically to your watch model.
The 

DS

 (Double Security) concept is characterised by:

– its scratch and impact resistance,

– its tough sapphire crystal,

– a gasket inside the crown and a gasket around the winding stem guar-

anteeing the water resistance of the watch even when the crown is 

pulled out,

– a reinforced case back.

Recharging the accumulator

Models with screwed crown

To ensure even better water resistance, certain models are fitted with 
a screwed crown. Before setting the time, date* or day*, you must first 
unscrew the crown into position 

IB

 before you can pull it out to position 

II

 

or 

III

.

Important: After every operation, the crown must be screwed back in to 
maintain the water-resistance of the watch.

Quartz watches

Quartz watches are battery powered, and cannot be recharged.

Autoquartz watches

To wind an Autoquartz watch, turn the crown through a few dozen 
(~50) revolutions in position 

I

 (or IB for models with screwed crown).  

The automatic winding system will then ensure that the watch is fully 
wound by means of your wrist movements alone. The watch needs to be 
worn for several weeks to reach maximum charge, and thereby achieve 
its theoretical power reserve of 100 days. 

Quartz solar watches

These watches do not have a winding crown. To recharge the accumulator, 
expose the dial of your watch either to the sun or to artificial light.

Settings

NB: Please take account of the information above if your watch is 
fitted with a screwed crown.
Setting the time

Pull the crown out to position 

III

 and turn it in either direction until the 

desired time is displayed.
On certain models with a seconds hand, you can synchronize it with an 
official time signal (radio/TV/Internet). When the crown is pulled out to 
position

 III

, the seconds hand is stopped. Once the time is synchronised, 

push the crown back into position 

I

 (and screw it back in on models with 

a screwed crown). 

Rapid correction of the date* and day*
NB: Do not perform a rapid date correction between 22:00 and 
02:00.

Pull the crown out to position 

II

 and turn it clockwise until the desired date 

is displayed, or counterclockwise to correct the day. During this operation, 
your watch will keep operating, so you will not need to adjust the time.

Technical information

CERTINA

®

 quartz watches

Boasting the precision of quartz, they generally have a power reserve 
of more than 2 years in continuous use, though this varies slightly 
depending on the habits of the wearer and the ambient temperature. 
Similarly, the ambient temperature may affect the accuracy of quartz 
movements, causing variations of around -0.5 to +0.7 seconds per day. 
All you have to do is to set the time, and possibly the date if your watch 
is equipped with a display of this kind (see the “Settings” section).

EOL Function – (End of Life) 

The battery end of life is indicated by the seconds hand making 4-second 
jumps. The watch will keep operating for a few more days, but the battery 
should be removed and replaced by an approved CERTINA

®

 service centre 

as soon as possible.

CERTINA

®

 Autoquartz watches

As accurate as a quartz watch yet operating without a battery, these 
watches are equipped with an accumulator which automatically recharges 
its energy by means your wrist movements. The oscillation movements of 
your wrist turn an oscillating weight, each rotation of which activates 
a micro-generator which in turn charges an accumulator with electrical 
energy. 

Power supply

The lithium accumulator has an average service life of more than 
10 years. Never replace it with a conventional silver oxide battery, since 
this would irrevocably destroy the movement.

EOE Function – (End of Energy)

Your CERTINA

®

 Autoquartz watch is equipped with an EOE (End of Energy) 

energy requirement indicator. If you observe the seconds hand jump 
every 4 seconds, it means that your watch needs to be wound (see the 
“Winding” section). 

Water-resistance

CERTINA

®

 watches are designed to withstand a pressure of up to 3 

bar (30 m / 100 ft), 5 bar (50 m / 165 ft), 10 bar (100 m / 330 ft), 20 bar 

(200 m / 660 ft) or 30 bar (300 m / 1000 ft), depending on the information 

shown on the case-back.
A watch cannot be permanently guaranteed absolutely water-resistant. 

It may be affected by ageing of the gaskets or by an accidental impact on 

the watch. We recommend that you have your watch’s water resistance 

checked once a year by an approved CERTINA

®

 service centre.

Care and maintenance

Temperature

Do not expose your watch to sudden temperature changes (exposure to 

sunlight followed by immersion in cold water) or extreme temperatures 

(over 60°C (140°F) or below 0°C (32°F).

Magnetic fields

Do not expose your watch to intense magnetic fields such as those 

generated by loudspeakers, mobile phones, computers, refrigerators or 

other electromagnetic appliances.

Shocks and impacts

Avoid thermal shocks or impacts, since they may harm your watch.  

In the event of a violent impact please have your watch checked by an 

approved CERTINA

®

 service centre.
