PRECIDRIVE Moon Phase Quartz Chronographs
Technical information
Winding
Quartz watches do not need to be wound.
PRECIDRIVE
PRECIDRIVE quartz chronographs, from CERTINA
®
, can boast not only the precision of quartz, but also their temperature variation compensated
(thermocompensated) rate, making them insensitive to moisture. This enables them to achieve a precision of around +/- 10 seconds per year (under normal
conditions of use).
EOL (End of Life) function
When the seconds hand 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 meticulous standards of
service and to ensure your guarantee remains in force, please 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 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.

pusher (B) to turn it anticlockwise. When one of the pushers is held down, the rotation speed will
increase (Fig. 5).
