- Button Tone: Enable or disable button press tones.
Operating Modes
The North Edge Apache watch features multiple modes accessible via the mode button (usually labeled 'MODE' or similar). Pressing this button cycles through the different functions.
1. Altimeter Mode

Image: The watch face showing altitude (186m) and temperature (25.7°C) in Altimeter mode. This mode is crucial for tracking vertical movement during outdoor activities.
This mode displays your current altitude and temperature. It also tracks altitude trends. For accurate readings, it is recommended to calibrate the altimeter before use, especially when starting an activity at a known altitude.
- Calibration: In Altimeter mode, press and hold the 'ADJUST' button to enter calibration. Set a known reference altitude if available.
- Altitude Range: -698m to +9164m (-2246ft to +30067ft).
2. Barometer Mode

Image: The watch face showing barometric pressure (1008.2 hPa) and current time in Barometer mode. This function helps in predicting weather changes.
The barometer measures atmospheric pressure and displays a trend chart, which can be used to forecast weather changes. A falling pressure often indicates worsening weather, while rising pressure suggests improving conditions.
- Pressure Range: 300hPa to 1100hPa (8.859inHg to 32.484inHg).
- Weather Forecast: The watch provides a basic weather forecast based on pressure trends.
3. Compass Mode

Image: The watch face showing compass direction (EME for East-Middle-East) and current time. The compass is essential for navigation in unfamiliar terrain.
The digital compass provides directional bearings. For accurate readings, ensure the watch is held horizontally and away from strong magnetic fields. Calibration is recommended periodically or when moving to a new geographical area.
- Calibration: In Compass mode, follow on-screen prompts or manual instructions to perform a figure-eight calibration.
4. Thermometer Mode
Displays the ambient temperature. For accurate temperature readings, remove the watch from your wrist for at least 15-20 minutes to allow it to equalize with the surrounding air temperature, as body heat can affect the sensor.
- Temperature Range: -10°C to +60°C (14°F to 140°F).
5. Pedometer Mode
The pedometer tracks your steps, calculates distance, and estimates calories burned. Ensure your personal stride length and weight are set correctly in the watch settings for optimal accuracy.
- Pacer Function: Helps maintain a consistent pace during activities.
6. Stopwatch Mode
Use the stopwatch to measure elapsed time. It typically includes start, stop, and reset functions, and may offer lap time recording.
- Maximum Time: 99 hours, 59 minutes, 59.99 seconds.
7. Countdown Timer Mode
Set a specific time for the watch to count down from. An alarm will sound when the countdown reaches zero.
- Maximum Time: 99 hours, 59 minutes, 59 seconds.
8. Alarm Clock Mode
The watch includes two independent alarm settings. Set the desired time for each alarm. Alarms can be set for daily repetition.
9. World Time Mode
View the current time in various major cities around the world. This mode often includes automatic daylight saving time adjustments.
10. EL Backlight
Press the backlight button (refer to watch diagram) to illuminate the display for easy reading in dark conditions. The backlight duration may be adjustable in settings.
Maintenance
Battery Replacement
The watch uses a CR2032 battery. When the low battery indicator appears, it is recommended to replace the battery promptly. Battery replacement should ideally be performed by a qualified technician to ensure water resistance is maintained.
- Battery Type: CR2032 (1 included).
Water Resistance
The watch is water-resistant up to 5 ATM (50 meters), suitable for swimming and showering. However, it is important to avoid pressing buttons underwater and exposing the watch to hot water or steam, as this can compromise the seals.
Cleaning
Clean the watch case and strap 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 harsh chemicals or abrasive materials.
Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Inaccurate Altimeter/Barometer/Thermometer Readings | Sensors may need calibration. Calibrate altimeter at a known altitude. For temperature, remove watch from wrist for 15-20 minutes. |
| Compass Inaccuracy | Magnetic interference or need for calibration. Perform compass calibration away from electronic devices or metal objects. |
| Display is Dim or Blank | Low battery. Replace the CR2032 battery. |
| Buttons Not Responding | May be stuck or watch needs a reset. Try a soft reset (refer to manual for specific model reset procedure, if available). Avoid pressing buttons underwater. |
| Water Inside Watch | Water resistance compromised. Avoid hot water/steam, ensure crown/buttons are not pressed underwater. Seek professional repair immediately. |
