Water Resistance (5ATM)
The NORTH EDGE Fortress watch is rated for 5ATM (50 meters / 164 feet) water resistance. This means it is suitable for:
- Daily use and exposure to water splashes.
- Rain.
- Hand washing.
It is not recommended for showering, swimming, diving, or any activities involving prolonged submersion or high-pressure water exposure. Do not operate buttons while the watch is wet or submerged.

Battery Information
The NORTH EDGE Fortress watch uses a CR2016 battery. The battery is included and pre-installed. Battery life can vary depending on usage, especially frequent use of the backlight and alarm functions.
When the digital display becomes dim or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.

Maintenance and Care
- Cleaning: Wipe the watch regularly with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth and mild soap, then rinse and dry thoroughly.
- Avoid Chemicals: Do not expose the watch to solvents, detergents, perfumes, or cosmetics, as these can damage the case, strap, or seals.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect its accuracy and water resistance.
- Impact: While durable, avoid strong impacts or dropping the watch.
Troubleshooting
Analog Hands Not Matching Digital Time
If the analog hands do not align with the digital time after setting, ensure you have completed the digital time setting process correctly. The analog hands should automatically synchronize. If not, try resetting the watch (refer to the full manual if available for specific reset procedures, or remove and reinsert the battery if comfortable doing so, which will require re-setting all functions).
Digital Display Not Visible or Dim
This usually indicates a low battery. Replace the CR2016 battery. If the issue persists after battery replacement, contact customer support.
Backlight Not Working
Check the battery. If the battery is low, the backlight may not function or may be very dim. If the battery is new and the backlight still doesn't work, there may be an internal issue requiring professional service.
