2.1 Watch Components
- Crown: Used for setting time and date.
- Push Buttons: Located on the side of the case, these may be used for specific sub-dial adjustments.
- Main Dial: Displays hours, minutes, and seconds.
- Sub-dials:
- Day Sub-dial: Indicates the day of the week.
- Date Sub-dial: Indicates the day of the month.
- 24-Hour Sub-dial: Displays time in a 24-hour format, synchronized with the main hour hand.
- Bracelet: Black textured adjustable link bracelet with a fold-over push-button clasp.
3. Setup and Operation
3.1 Setting the Time
- Pull the crown out to the second click position. The second hand will stop.
- Rotate the crown to move the hour and minute hands to the desired time. Ensure the 24-hour sub-dial also reflects the correct AM/PM period.
- Once the correct time is set, push the crown back into the normal position. The second hand will resume movement.
3.2 Setting the Date and Day
- Pull the crown out to the first click position.
- Rotate the crown in one direction (e.g., clockwise) to adjust the date sub-dial.
- Rotate the crown in the opposite direction (e.g., counter-clockwise) to adjust the day sub-dial.
- Avoid setting the date or day between 9:00 PM and 3:00 AM, as this may interfere with the automatic date change mechanism. If adjustment is needed during this period, first set the time outside this range, adjust the date/day, then reset the time.
- Once the correct date and day are set, push the crown back into the normal position.
3.3 Using the Multi-Function Dials
The day, date, and 24-hour sub-dials operate in conjunction with the main time setting. The 24-hour sub-dial automatically synchronizes with the main hour hand, indicating whether the main time is AM or PM.
4. Maintenance and Care
4.1 Water Resistance
Your Armitron 20/5198BKTI watch is water resistant to 50 meters (165 feet). This rating means the watch is suitable for short periods of recreational swimming. It is not suitable for diving, snorkeling, or prolonged water immersion. Always ensure the crown is fully pushed in before any contact with water.
4.2 Cleaning
To maintain the appearance of your watch, wipe the case and bracelet regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
4.3 Battery Replacement
This watch is powered by a Japanese-quartz movement and requires one product-specific battery (included). When the watch stops or the second hand begins to skip, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
5. Troubleshooting
- Watch not running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
- Date/Day not changing: Ensure the time is set correctly, passing midnight. If the issue persists, the date/day mechanism may require inspection by a technician.
- Condensation under crystal: This may indicate a loss of water resistance. Avoid further contact with water and seek professional service immediately.
