3. Setup Instructions
3.1 Setting the Time
- Pull the crown (the knob on the side of the watch) out to the second click position.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the desired time.
- Push the crown back in to the normal position to start the watch.
3.2 Setting the Day and Date
The watch features separate subdials for day and date. These are typically adjusted using the pushers located on the side of the watch case, adjacent to the crown. Refer to the specific markings on your watch for precise pusher functions.
- Date Subdial: Use the upper pusher to advance the date.
- Day Subdial: Use the lower pusher to advance the day of the week.
- 24-Hour Subdial: This subdial typically synchronizes with the main hour hand and does not require separate adjustment.
Note: Avoid adjusting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
3.3 Adjusting the Bracelet
The silver-tone adjustable link bracelet can be sized for a comfortable fit. For precise adjustment, it is recommended to visit a professional jeweler or watch repair service to add or remove links. The bracelet features a fold-over clasp with a safety mechanism for secure wearing.
4. Operating Instructions
4.1 Water Resistance
Your Armitron watch is water resistant to 50 meters (165 feet). This rating indicates that the watch is generally suitable for short periods of recreational swimming. It is not suitable for diving or snorkeling. Avoid operating the crown or pushers while the watch is wet or submerged.

5. Maintenance
5.1 Cleaning Your Watch
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, as these can damage the finish.
5.2 Battery Replacement
The watch is powered by a Japanese-quartz movement, which requires a battery. When the watch stops or the timekeeping becomes erratic, it indicates that the battery needs replacement. It is highly recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
5.3 Storage
When not wearing your watch, store it in a cool, dry place, away from direct sunlight and extreme temperatures. The original watch box provides excellent protection for storage.
6. Troubleshooting
If you encounter issues with your Armitron watch, please refer to the following common problems and solutions:
- Watch Not Running: This is most commonly due to a depleted battery. Refer to section 5.2 for battery replacement.
- Incorrect Time/Date: Ensure the crown is fully pushed in after setting. If the time or date frequently resets, check if the crown or pushers are accidentally being engaged.
- Condensation Under Crystal: If condensation appears under the crystal, it may indicate a breach in the water resistance. Avoid further exposure to water and seek professional service immediately.
