Your watch features both analog and digital time displays. Refer to the detailed instructions in the 'Operating' section for setting both displays accurately.
Operating
1. Button Functions
The watch features multiple buttons for various functions. Typically, these buttons are located on the sides of the watch case. Consult the specific module instructions (Module 3321) for precise button assignments and functions.
2. Setting Analog Time
To set the analog time, pull out the crown (usually on the right side of the watch) and rotate it to move the hour and minute hands to the desired time. Push the crown back in to start timekeeping.
3. Setting Digital Time and Date
Use the 'MODE' button to cycle through the digital display modes (Time, Date, Alarm, Stopwatch, Dual Time). Use the 'ADJUST' button to select the digit to be set and the 'H-SET' or other designated buttons to change the values. Confirm settings by pressing 'MODE' or 'ADJUST' again as per the module instructions.
4. Dual Time Function
The dual time feature allows you to display a second time zone. Access this mode via the 'MODE' button and set the desired second time zone using the adjustment buttons.

7. Hourly Time Signal
The hourly time signal can be activated or deactivated in the appropriate mode, causing the watch to emit a short beep every hour on the hour.
8. Auto Calendar
The watch features an auto calendar that automatically adjusts for different month lengths, including leap years.
9. 12/24 Hour Formats
The digital display can be toggled between 12-hour and 24-hour time formats as per user preference.
Maintenance
1. Battery Replacement
The watch uses a SR920W battery with an approximate life of 3 years. When the display dims or functions become erratic, it may be time for a battery replacement. It is recommended to have battery replacement performed by a qualified watch technician to ensure proper sealing and water resistance.
2. Water Resistance
This watch is 50M water resistant. This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water. It is not recommended for swimming, diving, or prolonged water activities. Avoid operating buttons while the watch is wet.
3. Cleaning
To clean your watch, wipe it with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners or abrasive materials, as these can damage the watch's finish.
Troubleshooting
1. Time Inaccuracy
The watch has an accuracy of +/-30 seconds per month. If you experience significant deviation, ensure the time is set correctly. Extreme temperatures or strong magnetic fields can affect accuracy.
2. Digital Display Issues
If the digital display is blank, dim, or showing incorrect characters, the battery may be low or require replacement. If the issue persists after battery replacement, consult a service center.
3. Buttons Not Responding
Ensure the buttons are not jammed or obstructed. If the watch has been exposed to water, ensure it is completely dry before attempting to operate the buttons. If buttons remain unresponsive, professional inspection may be required.
