Setup
Initial Charging
Your watch is powered by solar energy. Before initial use, or if the watch has stopped, expose the dial to bright light (natural sunlight is ideal) for several hours to ensure it is sufficiently charged. Avoid covering the watch with clothing for extended periods.
Time Setting and Radio Reception
The watch automatically receives time signals to maintain accurate time. Ensure the watch is placed in an area with good radio signal reception, typically near a window, especially during nighttime hours when signals are strongest. The watch will attempt to receive a signal automatically. If manual adjustment is needed, refer to the detailed instructions for your specific module (Caliber No. UP08) on the official CITIZEN website.
Time Zone Adjustment
While radio-controlled, you may need to manually set your home city or time zone. Consult the full instruction manual for Caliber UP08 for specific steps on adjusting the time zone.
Operating the Watch
Time Display
The watch features both analog (three-hand: hour, minute, second) and digital displays. The digital display can show time (hour, minute, day of week) or date (month, day, day of week).
- 12/24 Hour Display: The digital display supports switching between 12-hour and 24-hour formats.
Calendar
The digital display includes a full auto calendar, which automatically adjusts for different month lengths and leap years until 2099. The display shows Month, Day, and Day of Week.
Chronograph
The chronograph function allows for precise measurement of elapsed time. Refer to the detailed operating guide for Caliber UP08 for instructions on starting, stopping, and resetting the chronograph.
Alarm
The watch is equipped with one alarm, which sounds for approximately 15 seconds on the digital display. It includes an on/off switching function.
Hourly Chime
An hourly chime function is available, sounding every hour on the digital display. This feature also has an on/off switching function.
Dual Time
The dual time function allows you to display a second time zone, settable in 15-minute increments on the digital display.
LED Light
The watch features an LED light for illumination in low-light conditions. A single activation lasts approximately 2 seconds.
Maintenance
Solar Charging Guidelines
To ensure continuous operation, regularly expose your watch to light. When fully charged, the watch can operate for approximately 12 months without further charging, or up to 18 months when stored in power-saving mode. Insufficient charging may lead to the watch stopping or functions not operating correctly.
Care and Cleaning
Clean the watch case and band regularly with a soft, dry cloth. For stainless steel parts, a slightly damp cloth can be used, followed by drying. Avoid using harsh chemicals or abrasive materials.
Troubleshooting
Inaccurate Time
If the time is inaccurate and radio wave reception has not been successful, the watch's accuracy defaults to an average monthly difference of ±30 seconds. Ensure the watch is in a location conducive to signal reception. If issues persist, manual time adjustment may be necessary.
Watch Not Functioning
If the watch stops or functions are not working, it may be due to insufficient charge. Expose the watch to bright light for an extended period. If the problem continues, contact customer support.
