Setup
Setting the Time and Date
- Pull the Crown: Gently pull the crown (the small knob on the side of the watch) out to position 2.
- Set the Date: Rotate the crown clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
- Set the Day: Pull the crown out further to position 3. Rotate the crown to adjust the day.
- Set the Time: Continue rotating the crown to set the correct time. Ensure you distinguish between AM and PM when setting the time, especially for the day/date change.
- Push the Crown Back: Once the time, day, and date are set, push the crown back into position 1 (flush with the watch case) to start the watch and ensure water resistance.

Operating the Watch
Your Armitron watch is designed for straightforward operation. Once the time, day, and date are set, the Japanese quartz movement ensures accurate timekeeping. The day and date will automatically advance at midnight.
- Time Display: The watch displays hours, minutes, and seconds using silver-tone luminous hands.
- Day/Date Window: The window at the 3 o'clock position shows the current day of the week and the numerical date.
- Outer Minute Track: The white printed outer minute track assists in precise time reading.
Maintenance
Cleaning
To maintain the appearance of your watch, wipe it regularly with a soft, dry cloth. For the metal bracelet, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
Water Resistance
This watch is water resistant to 165 feet (50 meters). This rating means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Always ensure the crown is fully pushed in to maintain water resistance. Avoid operating the crown while the watch is wet or submerged.
