2. Setup
2.1 Initial Time and Date Setting
To set the time and date on your Armitron Sport watch, follow these general steps. Specific button labels (e.g., MODE, RESET, ST/STP, EL) are typically found on the watch case.
- Press the MODE button repeatedly until the time setting mode is activated. Digits to be set will usually flash.
- Use the RESET or ST/STP buttons to adjust the flashing digits (hours, minutes, seconds, month, day, year).
- Press the MODE button to move to the next setting field.
- Once all settings are adjusted, press the MODE button to exit the setting mode and return to normal time display.
2.2 Battery Information
The watch comes with 1 product-specific battery included. When the display dims or functions become erratic, it may indicate a low battery. Battery replacement should ideally be performed by a qualified technician to ensure water resistance is maintained.
3. Operating Instructions
Your Armitron Sport watch offers several useful functions. Familiarize yourself with the buttons and their corresponding actions.
- Chronograph (Stopwatch):
To use the chronograph, press the MODE button repeatedly until the chronograph display appears (usually showing 00:00:00). Press ST/STP to start and stop the timer. Press RESET to clear the timer to zero.
- Lap Time:
While the chronograph is running, press RESET to record a lap time. The display will momentarily show the lap time before returning to the running total. Press ST/STP to stop the chronograph, then RESET to clear.
- Alarm:
Navigate to the alarm setting mode using the MODE button. Use RESET or ST/STP to set the desired alarm time. Once set, ensure the alarm icon is visible on the display to confirm it is active. The alarm will sound at the set time daily until deactivated.
- Dual Time:
This function allows you to set and display a second time zone. Access the dual time mode via the MODE button and adjust the time using the RESET or ST/STP buttons.
- Military Time (24-Hour Format):
The watch supports both 12-hour (AM/PM) and 24-hour (military) time formats. This setting is usually toggled within the main time setting mode by pressing a specific button (often ST/STP) while setting the hour.
- Backlight (EL):
To illuminate the display in low-light conditions, press the EL button. The backlight will typically stay on for a few seconds.
4. Maintenance
4.1 Water Resistance
Your Armitron Sport watch is water resistant to 330 feet (100M). This means it is generally suitable for swimming and snorkeling, but not for scuba diving. Avoid pressing buttons underwater to prevent water ingress.

4.2 Cleaning and Care
To maintain your watch's appearance and functionality:
- Wipe the watch case and strap regularly with a soft, damp cloth.
- For the nylon strap, mild soap and water can be used, ensuring it is thoroughly rinsed and air-dried.
- Avoid exposing the watch to extreme temperatures or direct sunlight for prolonged periods.
- Do not use harsh chemicals or abrasive cleaners on the watch.
5. Troubleshooting
If you encounter issues with your watch, refer to the following common problems and solutions:
- Display is blank or dim:
The battery may be low or depleted. Replace the battery. If the issue persists after battery replacement, contact customer support.
- Time is incorrect:
Re-enter the time setting mode and adjust the time and date as described in Section 2.1. Ensure you are exiting the setting mode correctly.
- Alarm is not sounding:
Check if the alarm function is activated (look for the alarm icon on the display). Ensure the alarm volume is not set to zero if applicable (though most digital watches have fixed alarm sounds).
- Buttons are unresponsive:
Ensure the watch is not in a locked mode (if applicable). If the watch has been exposed to water, ensure it is completely dry. If the problem persists, the internal mechanism may require professional inspection.
