Setup and Initial Adjustment
Before wearing your watch, it is important to set the correct time, day, and date.
Setting the Time
- Locate the crown on the right side of the watch case.
- Gently pull the crown out to the second position (farthest out).
- Rotate the crown clockwise or counter-clockwise to move the hour and minute hands until the correct time is displayed. Ensure to account for AM/PM if setting the date later.
- Once the time is set, push the crown back in fully to the first position (normal operating position) to start the watch movement.
Setting the Day and Date
The watch features a quick-set function for the day and date. Avoid setting the date between 9:00 PM and 3:00 AM, as this can interfere with the automatic date change mechanism.
- Gently pull the crown out to the first position (one click out from fully pushed in).
- Rotate the crown clockwise to adjust the date.
- Rotate the crown counter-clockwise to adjust the day of the week.
- Once the day and date are set, push the crown back in fully to the normal operating position.

Operating Your Watch
Your Armitron watch is designed for daily wear and reliable performance.
Water Resistance
This watch is water resistant to 165 feet (50 meters). This rating means the watch is suitable for short periods of recreational swimming. It is not suitable for diving, snorkeling, or prolonged water activities. Avoid operating the crown or pushers when the watch is wet, as this can compromise the water resistance.
Luminous Features
The gold-tone hands and markers are treated with a luminous material that absorbs light and glows in the dark. For optimal glow, expose the watch face to a bright light source for a few minutes before entering a dark environment.

Maintenance and Care
Proper care will ensure the longevity and performance of your Armitron watch.
Cleaning
- Wipe the watch case and band regularly with a soft, dry cloth to remove dust and dirt.
- For the expansion band, a slightly damp cloth can be used, ensuring to dry it thoroughly afterwards.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish.
Battery Replacement
The watch is powered by a quartz movement and requires a battery. 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 maintain water resistance.
Storage
When not in use for extended periods, store your watch in a cool, dry place away from direct sunlight and extreme temperatures. Keeping it in its original box or a watch case can help protect it from dust and scratches.
