Maintenance - Citizen NB0 SERIES Instruction Manual

<When Luminous Paint is used for your watch>
The paint on the dial and hands helps you with reading the time in a dark place. The luminous paint
stores light (daylight or artificial light) and glows in a dark place.
It is free from any radioactive substance or any other material harmful to a human body or
environment.
• The light emission will appear bright at first and then diminish as time passes.
• The duration of the light ("glow") will vary depending on the brightness, types of and distance from
a light source, exposure time, and the amount of the paint.
• The paint may not glow and/or may dissipate quickly if exposure to light was not sufficient.

Maintenance

<Daily maintenance>
• Rotate the crown while it is pressed in fully and press the buttons periodically so they do not become
stuck due to accumulations of foreign matter.
• Wipe off dirt, perspiration, and water from the case and glass with a clean soft cloth occasionally.
• 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 a polishing type of cloth as this may damage the surface and certain treatments.
• 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 gaskets and other components need to be replaced regularly. Other parts need
to be inspected and replaced if necessary.
Always ask for genuine Citizen parts upon replacement.
