WARNING: 

Water-resistance performance 

• 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. 

CAUTION 

• Be sure to use the watch with the crown pressed in (normal position). If your watch has a

screw-lock type crown, be sure to tighten the crown completely. 

• Do NOT operate the crown  or button 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 if the inside of the crystal is fogged up and does not

become clear within a day, immediately take the watch to your dealer or Citizen Service
Center 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 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 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 damage the finish.
