2.5 Setting the Time
Once the clock is mounted and the battery is installed, gently turn the minute hand clockwise until the desired time is displayed. The hour hand will automatically adjust. Avoid moving the hour hand directly, as this may damage the mechanism.

4. Maintenance
4.1 Battery Replacement
To ensure continuous and accurate operation, replace the AA battery approximately once a year. Promptly replace depleted batteries to prevent potential leakage and damage to the clock mechanism.
4.2 Cleaning
To clean the clock, gently wipe the metal frame, Roman numerals, and hands with a soft, dry, lint-free cloth. Avoid using abrasive cleaners, chemical sprays, or solvents, as these can damage the finish and materials.
5. Troubleshooting
5.1 Clock Not Running
- Check Battery: Ensure the AA battery is correctly installed with the proper polarity and has sufficient charge. Replace with a new alkaline battery if necessary.
- Hand Obstruction: Verify that the clock hands are not bent, touching each other, or obstructed by the clock face or frame. Gently adjust them if needed, taking care not to apply excessive force.
5.2 Inaccurate Time
- Replace Battery: A weak battery can cause the clock to run slowly or stop intermittently. Replace the battery with a fresh AA alkaline battery.
