The Amazfit Cheetah Pro in Run Track Black is a specialized smartwatch designed for athletes who need precise tracking and durable build quality. Its 1.45-inch AMOLED display with a resolution of 480 x 480 pixels provides clear visibility, protected by Corning Gorilla Glass 3 featuring an anti-fingerprint coating to keep the screen clean during intense activity. The structure is built for resilience, combining a titanium alloy bezel with a fiber-reinforced polymer middle frame, while the nylon strap in Run Track Black ensures a comfortable fit for wrists between 150 mm and 215 mm. For navigation, it utilizes a circularly-polarized GPS antenna and dual-band positioning across six satellite systems, allowing you to map your routes accurately for up to 54 hours in power saving mode. The BioTracker PPG sensor monitors blood oxygen levels alongside heart rate tracking, while the integrated microphone and speaker enable Bluetooth calling directly from your wrist. These capabilities are powered by a 440 mAh battery that lasts up to 14 days under typical use and can be fully recharged via the magnetic base in about two hours. Running Zepp OS, this watch supports 156 sports modes and is compatible with Android 7.0 or iOS 12.0 and above. Its 5 ATM water resistance means you can wear it during swims or rainy runs without worry. Weighing only 43 g with the strap, it remains unobtrusive during long-distance training sessions where every gram counts.
