Setup
Initial Inspection:
Upon receiving your watch, carefully inspect it for any signs of damage. Ensure all components are present and the watch is functioning correctly.
Setting Time and Date:
- Pull out the crown: Gently pull the crown (the knob on the side of the watch) to the first click position.
- Set the date: Rotate the crown clockwise or counter-clockwise to adjust the date. Adjust the date to the day before the current date.
- Pull out the crown further: Pull the crown out to the second click position. The second hand will stop.
- Set the time: Rotate the crown to advance the hour and minute hands. Continue rotating until the date changes to the current date, indicating it is midnight (AM). Then, set the watch to the current time. Ensure you set the correct AM/PM.
- Push in the crown: Once the time and date are set, push the crown back into its normal position. The second hand will resume movement.
Operating
Day-Date Function:
Your Armitron watch features a day and date display. The day and date will automatically advance at midnight. If the watch stops or the date needs adjustment due to months with fewer than 31 days, refer to the "Setting Time and Date" section.
Note: Avoid adjusting the date between 9:00 PM and 3:00 AM, as this can interfere with the automatic date change mechanism and potentially damage the movement.
Maintenance
Cleaning Your Watch:
To maintain the appearance of your watch, wipe the case and band 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, as these can damage the watch's finish.
Water Resistance:
This watch is water resistant to 50 meters (165 feet). This rating means it is generally suitable for short periods of recreational swimming, but it is not designed for diving or snorkeling. Avoid operating the crown or pushers while the watch is wet or submerged, as this can compromise the water resistance.
Exposure to hot water, steam, or sudden temperature changes (e.g., hot shower followed by cold water) can also affect the watch's water resistance over time. Always ensure the crown is fully pushed in before exposing the watch to water.
Battery Replacement:
Your watch is powered by a quartz movement and requires a product-specific battery (included). When the battery needs replacement, it is recommended to take your watch to a qualified watchmaker or an authorized service center. Attempting to replace the battery yourself may void the warranty and could damage the watch.
Troubleshooting
If you encounter issues with your watch, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently. | Low battery or internal movement issue. | Replace battery (professional service recommended) or consult a watchmaker. |
| Date/Day does not change at midnight. | Time set incorrectly (AM/PM) or date adjusted during restricted hours. | Reset the time and date following the instructions in the "Setup" section, ensuring correct AM/PM. |
| Condensation inside the crystal. | Exposure to extreme temperature changes or compromised water resistance. | Immediately take the watch to a professional watchmaker for inspection and repair to prevent damage. |
If the problem persists after attempting these solutions, please contact Armitron customer support or an authorized service center.
