Maintenance

Daily maintenance

• Rotate the crown while it is pressed in (position  ) and press the buttons periodically 

so that they will not be rusty.

• Wipe off dirt, perspiration, and water from the case and glass with a soft cloth.
• To clean a metal, plastic, or rubber watchband, wash away dirt with water. Use a soft 

brush to remove dust and dirt stuck in the gaps in a metal band.

• Do not use solvents (thinner, benzine, etc.), as they may damage the finish.

Periodical inspections

Your watch needs an inspection once every two or three years for safety and longer usage. 
To keep your watch water-resistant, the packing needs to be replaced regularly.
Other parts need to be inspected and replaced if necessary.
Ask for genuine Citizen parts upon replacement.
