GT4 PRO Bluetooth Call, GPS, NFC Waterproof Sports Smartwatch

The GT4 PRO RD Fit elevates your wrist game with a 1.6″ ultra-clear IPS touchscreen and gesture controls—plus an always-on analog watch face for classic flair. Choose from multiple preloaded faces or customize your own in the companion app. A precision 8763EW chipset powers smooth performance, while the robust stainless-steel case and comfortable strap (fits 140–210 mm wrists) stand up to daily wear.

Track every move with the RD Fit health suite: continuous heart-rate and SpO₂ monitoring, full sleep staging with quality scoring, plus a built-in barometer altitude gauge. Multi-satellite GPS locks on to your route in challenging terrain, and dedicated sports modes give you real-time metrics for running, cycling, hiking, swimming, and more.

Stay connected without pulling out your phone—Bluetooth 5.0 lets you make and receive calls right from your wrist, with a built-in speaker and mic for crystal-clear audio. Multi-function NFC handles door-lock card emulation, one-tap health codes and offline Alipay payments. Receive notifications, control your camera remotely, check weather and calendar events or set hydration alerts—all at a glance.

Power through your week and beyond: the IP68 waterproof design means you can swim or shower without worry. A 300 mAh battery and smart power-saving algorithms deliver up to 30 days of standby, 5–7 days of typical use, and a full wireless recharge in just 3 hours—so you’re always ready to go.
