Product description

This military-grade GPS smartwatch is built for outdoor adventurers, sports enthusiasts, and anyone who demands serious durability and functionality from their wearable. With IP69K and 10ATM waterproofing — rated to 100 metres depth — it handles swimming, diving, rain, and dust without hesitation. The 1.39-inch AMOLED display delivers a crisp 360 × 360 HD resolution, and the sapphire crystal glass screen resists scratches in the most demanding environments.

Packed with over 100 sports modes, dual-frequency GPS positioning, compass, altimeter, and barometer, it's a full outdoor navigation and fitness tool on your wrist. Health monitoring covers heart rate, blood oxygen, stress levels, sleep tracking, and 24-hour continuous health data — all accessible via the DAFIT app on Android and iOS. HD Bluetooth calls, an AI voice assistant with ChatGPT integration, and a built-in high-brightness flashlight round out an impressive feature set.

The 530mAh polymer battery delivers 7 to 10 days of regular use and up to 30 days on standby, charging fully in approximately 2 hours via the included wireless charger. The detachable 22mm silicone band and customisable watch faces make it as versatile in style as it is in function.
