CITIZEN QUARTZ Eco-Drive

A. BEFORE USING

This watch is powered not by an ordinary battery, but by converting photo energy to electrical energy.

Before using, expose to light and make sure the watch is sufficiently charged. See "F. TIME FOR CHARGING” for charging time reference.

A secondary battery is used in this watch to store electrical energy. This secondary battery is a clean battery which doesn't use any toxic substances such as mercury. Once fully charged, the watch will continue to run for about 16 months without further charging.

To use this watch comfortably, make sure that the watch is always recharged before it stops.

There is no concern for overcharging this watch (Overcharging Prevention Function is included). We recommend that you recharge the watch everyday.

Insufficient charge warning display

The second hand moves in two-second intervals. ⚠️ If insufficiently charged

Diagram shows a second hand moving in two-second intervals.

Time setting warning display

The second hand moves with a hitch. ⚠️ If insufficiently charged and time is set

Diagram shows a second hand in a 'Hitch movement'. A note indicates: "The watch will begin to operate soon after it is exposed to light due to Quick Start Function". A 'Stop' button is also indicated.

C. FUNCTIONS OF SOLAR POWERED WATCH (Continued)

Insufficient Charge Warning Function

The second hand changes to a two-second interval movement ↔️ to indicate insufficient charging. Even in such a case, the watch keeps correct time, but about 20 days after the two-second movement begins, the watch will stop. After exposing the watch to light, recharging takes place and the watch returns to one-second interval movement.

Diagram illustrating 'Two second interval movement' with label '2 sec 2 sec'.

Quick Start Function

The watch will stop if it is completely discharged. It will begin to operate soon after it is exposed to light. (However, the time to start may vary according to the brightness of the light.)

Time Setting Warning Function

If the watch stops, subsequent exposure to light allows the Quick Start Function to start again, and the second hand moves with a hitch ⚙️ to indicate that the time is incorrect.

Diagram illustrating 'Hitch movement' with label '2 sec 2 sec'.

In such a case, set the hands to the correct time.

NOTE: If the watch is insufficiently exposed to light, the second hand will soon switch to moving at two-second intervals in order to warn that the energy is running short.

E. REPLACING THE SECONDARY BATTERY

Unlike ordinary batteries, the secondary battery used in this watch doesn't have to be periodically replaced due to repeated charging and discharging.

CAUTION: Never use another battery different from the secondary battery used in this watch. The watch structure is so designed that a different kind of battery other than that specified cannot be used to operate it. In case a different kind of battery such as a silver battery is used by some chance, there is a danger that it will be overcharged to burst, causing damage to the watch and even to the human body.

F. TIME REQUIRED FOR CHARGING

The time required for charging may vary according to the caliber number, design (colour of the dial, etc.) and operating environment. The following table will serve as a rough reference.

*The recharging time is the time when the watch is continuously exposed to radiation.

Please check the caliber number on the caseback.

Caliber No. A160

Full recharging time (Empty to full)... The time for fully recharge from stopped.

One day usage... The time required for the watch to run for one day with one second interval movement.

Caliber No. A270

Full recharging time (Empty to full)... The time for fully recharge from stopped.

One day usage... The time required for the watch to run for one day with one second interval movement.

G. IN THESE CASES

If the watch warns that the energy is running short.

The second hand starts moving at two-second intervals ↔️ in order to warn that the watch will stop functioning after about 20 days. (Insufficient Charge Warning Function)

In such a case, expose your watch to light for a while to cancel the warning. (The second hand returns to moving at one-second intervals when the energy is recharged.) If the watch is left short of energy, it will stop functioning after 20 days or so.

Diagram illustrating 'Two second interval movement'.

If the watch warns you to set the time.

When the watch that has stopped is exposed to light, the second hand starts the hitch movement. (Quick Start Function)

The time elapsed before the second hand starts moving depends on the illuminance of the light. Even so, the second hand continues the hitch movement ⚙️ to tell you that the watch indicates an incorrect time because it has stopped. (Time Setting Warning function)

In such a case, set the hands to the correct time.

NOTE: If the watch is insufficiently exposed to light, the second hand will soon switch to moving at two-second intervals in order to warn that the energy is running short.

H. PRECAUTIONS

CAUTION: Water-resistance performance

There are several types of water-resistant watches, as shown in the following table. For correct use within the design limits of the watch, confirm the level of water-resistance of your watch, as indicated on the dial and case, and consult the table.

• Water-resistance for daily use (to 3 atmospheres): This type of watch is water-resistant to minor exposure to water. For example, you may wear the watch while washing your face; however, it is not designed for use underwater.
• Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is water-resistant to moderate exposure to water. You may wear the watch while swimming; however, it is not designed for use while skin diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of watch may be used for skin diving; however, it is not designed for scuba or saturated diving using helium gas.

Diagrams illustrate activities: washing face, kitchen work/swimming, skin diving, scuba diving, and operating buttons with moisture.

CAUTION

• Be sure to use the watch with the crown ? pressed in (normal position). If your watch has a screw type crown ?, be sure to tighten the crown ? completely.
• Do NOT operate the crown ? with wet fingers or when the watch is wet. Water may enter the watch and compromise water resistance.
• If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry cloth.
• If moisture has entered the watch, or the inside of the crystal has fogged up and does not become clear within a day, immediately take the watch to your dealer or Citizen Service Centre for repair. Leaving the watch in such a state will allow corrosion to form inside.
• If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown ?, buttons, etc.) may come off.

CAUTION: Keep your watch clean.

• Leaving dust and dirt deposited between the case and crown ? may result in difficulty in pulling the crown ? out. Rotate the crown ? while in its normal position, from time to time, to loosen dust and dirt and then brush it all off.
• Dust and dirt tend to be deposited in gaps in the back of the case or band. Deposited dust and dirt may cause corrosion and soil your clothing. Clean the watch occasionally.

Cleaning the Watch.

• Use a soft cloth to wipe off dirt, perspiration and water from the case and crystal.
• Use a soft, dry cloth to wipe off perspiration and dirt from the leather band.
• To clean a metal, plastic or rubber watchband, wash away the dirt with mild soap and water. Use a soft brush to remove dust and dirt jammed in the gaps in the metal band. If your watch is not water-resistant, take it to your dealer.

NOTE: Avoid using solvents (thinner, benzine, etc.) as they may mar the finish.

CAUTION: Operating environment.

• Use the watch within the operating temperature range specified in the instruction manual. Using the watch where the temperatures are outside the specified range, may result in deterioration of functions or even stoppage of the watch.
• Do NOT use the watch in places where it is exposed to high temperature, such as in a sauna. Doing so may result in a skin burn.
• Do NOT leave the watch in a place where it is exposed to high temperature, such as in the glove compartment or dashboard of a car. Doing so may result in deterioration of the watch, such as deformation of the plastic parts.

• Do NOT place the watch close to a magnet ?. Timekeeping will become inaccurate if you place the watch too close to magnetic health equipment such as a magnetic necklace or a magnetic latch of a refrigerator door or handbag clasp or the earphone of a mobile phone. If this has occurred, move the watch away from the magnet ? and reset the time.
• Do NOT place the watch close to household appliances that generate static electricity.
• Timekeeping may become inaccurate if the watch is exposed to strong static electricity, such as emitted from a TV screen.
• Do NOT subject the watch to a strong shock such as dropping it onto a hard floor.
• Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases.
• If solvents, such as thinner or benzine, or substances containing such solvents come in contact with the watch, discolouration, melting, cracking, etc. may result. If the watch comes into contact with mercury used in thermometers, the case, band or other parts may become discoloured.
