Operating Your Watch
Your Citizen Classic Quartz Watch is powered by a precise Japanese Quartz movement, which uses a battery to regulate timekeeping. Once the time and date are set, the watch will operate continuously until the battery needs replacement. The second hand moves in individual ticks, characteristic of a quartz movement.
Maintenance
- Cleaning: Wipe the watch case and bracelet regularly with a soft, dry cloth to remove dirt and oils. For stubborn grime, a slightly damp cloth can be used, followed by immediate drying.
- Water Resistance: This watch has a water resistance depth of 99 feet (30 meters). This rating means it is suitable for splashes, rain, and incidental contact with water. It is not suitable for showering, bathing, swimming, or diving. Avoid operating the crown when the watch is wet.
- Battery Replacement: When the watch stops or the second hand begins to skip, the battery may need replacement. It is recommended to have the battery replaced by an authorized Citizen service center or a professional jeweler to ensure proper sealing and maintain water resistance.
- Avoid Extreme Conditions: Protect your watch from extreme temperatures, strong magnetic fields, and harsh chemicals.
