Rugged Smart Watch for Android Users

The NAIXUES AK90 is a military-grade smart watch built for Android users who need a durable companion for outdoor work or adventure. It passes twelve military tests for ruggedness and offers a 5ATM water resistance rating. A built-in LED flashlight adds practical utility for camping or night-time emergencies. The device includes two silicone straps to suit different occasions.

Upgrade from Basic Trackers with Short Battery Life

This model replaces entry-level fitness bands that require daily charging and lack robust construction. The jump is worth it when you need up to thirty days of regular use or one hundred days of standby from the 1000 mAh battery. It also adds Bluetooth calling with SOS dial functionality and over one hundred sport modes for detailed activity tracking.

Limits of Bluetooth-Only Connectivity

The watch relies entirely on a Bluetooth link to a paired Android phone for calls, notifications and GPS positioning. It has no independent cellular or Wi-Fi capability, so range is limited by the phone connection. Onboard storage is fixed at 1 GB for watch faces and data, with no expansion slot. The 1.91 inch AMOLED display runs at 360 x 360 resolution.

Questions about this item

What wrist circumference does the 1.1 inch case with 1.91 inch AMOLED display fit?

How do I pair the AK90 for Bluetooth calls and SOS dial on Android?

Enable Bluetooth on the phone, open the companion app, select the AK90, confirm the pairing code, then grant call and contact permissions for Bluetooth calling and SOS.

When should I replace the two silicone bands on the AK90?
