Setup Instructions
Setting Analog Time
To set the analog time, gently pull out the crown located on the right side of the watch case. Rotate the crown to move the hour and minute hands to the desired time. Once set, push the crown back in to secure the time and activate the watch movement.
Setting Digital Time and Date
The digital display functions are controlled by the buttons on the sides of the watch. Refer to the button labels (MODE, RESET, ST/STP, EL) for specific functions. Typically, pressing the 'MODE' button cycles through different display modes (Time, Chronograph, Alarm, Dual Time). When in the time setting mode, use 'RESET' to select the digit to adjust and 'ST/STP' to change the value. Press 'MODE' again to confirm and exit setting mode.

Operating Instructions
Chronograph Function
To use the chronograph (stopwatch), press the 'MODE' button until the chronograph display appears. Press 'ST/STP' to start and stop the timer. Press 'RESET' to clear the timer back to zero. The chronograph can measure elapsed time, split times, and lap times.
Alarm Setting
Navigate to the alarm mode using the 'MODE' button. Use 'RESET' and 'ST/STP' buttons to set the desired alarm time. Activate or deactivate the alarm by pressing a specific button combination, usually indicated on the watch or in a more detailed diagram (not provided here).
Dual Time
The dual time feature allows you to display a second time zone. Access this mode via the 'MODE' button and set the time similarly to the main digital time, using 'RESET' and 'ST/STP'.
Backlight Activation
To illuminate the digital display in low-light conditions, press the 'EL' (Electroluminescent) button. The backlight will typically stay on for a few seconds.
Maintenance and Care
Water Resistance
Your Armitron Sport watch is water resistant to 330 feet (100M). This means it is suitable for recreational swimming and showering. Important: Do not press any buttons while the watch is submerged in water, as this can compromise the water resistance and lead to internal damage. Avoid exposing the watch to hot water or steam, which can also affect its seals.
Cleaning
Clean your watch regularly with a soft, damp cloth. For the resin strap, a mild soap solution can be used, followed by rinsing with clean water and drying thoroughly. Avoid using harsh chemicals or abrasive materials, which can damage the watch's finish.
Battery Replacement
When the battery needs replacement, it is recommended to take your watch to a qualified jeweler or watch repair facility. They have the necessary tools and expertise to replace the battery correctly and ensure the water resistance is maintained.
Troubleshooting
- Analog Time Not Moving: Check if the crown is fully pushed in. If it is, the battery may be low or depleted.
- Digital Display Blank or Faint: This typically indicates a low battery.
- Buttons Unresponsive: Ensure the watch is not in a locked mode (if applicable). If the issue persists, a battery replacement or professional inspection may be required.
- Water Inside Watch: If condensation or water appears inside the watch, immediately take it to a professional for inspection and repair to prevent further damage.
