4. Battery replacement of the professional diver's watch (Caliber 5503).
• This watch's battery needs to be replaced at the Citizen Service Center only.
• The Service Center will check water resistance and replace packings if
necessary at the time of battery replacement.
• If a dead battery is left in the watch, it may cause malfunctioning or damage
due to fluid leakage.
• If you are planning to use this watch for a long period of time in a foreign
country, we recommend that you have the battery replaced before you leave.
• Be sure to keep the battery out of reach of your children. If the battery is
accidentally swallowed by a child, take him or her immediately to a doctor.
