Maintenance; Information - Citizen E650 User Manual

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.

Information

The radio signal
The radio signal is broadcast almost continuously 24-hours a day, but may occasionally be
interrupted due to maintenance. The broadcasting conditions of the radio signal can be checked on
the station web site.
The radio signal has no effect on the human body or medical equipment.
Luminous Feature
Your watch may feature luminous treatment to the dial and hands to aid you in reading the watch
in dimly lit environments. This luminous treatment stores light from both natural and artificial
sources. It is free from any radioactive substance or any other material that may be harmful to the
environment or human body.
• The light emission of the luminous material gradually decreases as time passes.
• The duration and amount of light emitted will vary depending on the brightness, type of and
distance from the light source, exposure time and amount/size of luminous treatment.
• When not exposed to a light source, light emission from the luminous treatment will start off
bright and gradually diminish over a period of hours. The duration of visible light emission will
vary with type of and duration of light exposure as well as size of luminous features of your watch.
