Getting Started
Button Functions:
The watch typically features four main buttons for navigation and function control. While specific labels might vary, common functions are:
- LIGHT button (Top Left): Activates the EL backlight for visibility in low light conditions.
- MODE button (Bottom Left): Cycles through different watch modes (Time, Altimeter, Barometer, Compass, Pedometer, Stopwatch, Countdown, Alarm, Second Time).
- BARO button (Top Right): Often used for adjusting settings within a mode or accessing barometer/temperature readings directly.
- ALTI button (Bottom Right): Often used for adjusting settings within a mode or accessing altimeter readings directly.
Refer to the on-screen prompts and the watch's display for specific button interactions within each mode.
Initial Setup:
- Power On: The watch should be powered on out of the box. If the display is blank, check the battery.
- Time Setting:
- Press the MODE button until you reach the Time mode.
- Press and hold a designated button (often BARO or ALTI) to enter setting mode.
- Use the LIGHT and MODE buttons to adjust hours, minutes, seconds, year, month, and date.
- Press the setting button again to confirm and exit.
- Unit Settings: You may need to set units for altitude (meters/feet), temperature (Celsius/Fahrenheit), and pressure (hPa/inHg) in the settings menu.
Operating Modes
1. Altimeter Mode
The altimeter measures your current altitude and tracks altitude trends. It also displays the current temperature.


To access Altimeter mode, press the MODE button until "ALTI" is displayed. The watch will show the current altitude and temperature. You can often calibrate the altimeter by setting a known reference altitude.
2. Barometer Mode
The barometer measures atmospheric pressure and provides a weather forecast based on pressure trends. It also displays the current temperature.


To access Barometer mode, press the MODE button until "BARO" is displayed. The watch will show the current air pressure and a trend chart. This can help predict weather changes.
3. Compass Mode
The digital compass provides directional readings, indicating North and your current azimuth.

To access Compass mode, press the MODE button until "COMP" is displayed. It may require calibration before first use or after significant magnetic interference. Follow the on-screen instructions for calibration (e.g., rotating the watch in a figure-eight pattern).
4. Other Functions
- Pedometer: Tracks steps, calories burned, and distance. Activate in Pedometer mode.
- Stopwatch: For timing events. Start, stop, and reset using designated buttons.
- Countdown Timer: Set a specific time to count down from.
- Alarm: Set up to two alarms.
- Second Time: Displays time for a different time zone.
- Backlight: Press the LIGHT button to illuminate the display in the dark.
Maintenance
Water Resistance (50M / 5ATM):
The APACHE-46 is water-resistant up to 50 meters, making it suitable for swimming, showering, and other water-related activities. However, it is not recommended for diving or high-pressure water activities. Do not press any buttons while the watch is submerged in water.
General Care:
- Clean the watch regularly with a soft, damp cloth.
- Avoid exposing the watch to extreme temperatures or direct sunlight for prolonged periods.
- Keep the watch away from strong magnetic fields to prevent interference with the compass function.
- The watch is shock-resistant, but excessive impact should still be avoided.
Battery Replacement:
The watch uses a CR2032 battery. When the battery life reminder appears, it's time to replace it. It is recommended to have the battery replaced by a professional to ensure the water resistance seal is maintained.
Troubleshooting
- Display is blank: Check if the battery needs replacement.
- Incorrect time/date: Re-enter the time setting mode and adjust.
- Inaccurate compass readings: Perform a compass calibration. Ensure you are away from strong magnetic fields.
- Inaccurate altimeter/barometer readings: Calibrate the altimeter with a known reference altitude. Ensure the sensor is clean and unobstructed.
- Water inside the watch: Immediately stop using the watch and seek professional repair to prevent further damage.
User Tips
- For accurate altimeter and barometer readings, calibrate the watch regularly, especially when changing locations significantly.
- The EL backlight ensures visibility in the dark, making it suitable for night activities.
- Utilize the pedometer function to track your fitness goals during running, cycling, or climbing.
- The watch's durable construction is designed for tough conditions, but proper care will extend its lifespan.
