The Amazfit Cheetah 2 Pro is a specialized sports smartwatch designed for athletes who need precise tracking and durable construction. Its build features a Grade 5 titanium frame paired with aluminum buttons and a polymer bezel, while a scratch-resistant sapphire crystal protects the 1.32-inch AMOLED display. This screen reaches a peak brightness of 3,000 nits, ensuring that your metrics remain clearly visible even under direct, harsh sunlight. Weighing only 45.6 g without the strap, the watch remains unobtrusive during intense movement, and its 5 ATM water resistance allows you to wear it while swimming. For navigation and training, the device utilizes a circularly polarized antenna and dual-band GPS supporting six satellite systems, which helps you maintain an accurate path during outdoor runs. It includes 32 GB of storage for offline maps with turn-by-turn navigation and offers over 170 sports modes. Advanced runners can monitor specific metrics like lactic threshold, ground contact time, and left-right balance, while the Zepp Coach AI provides tailored training plans. The BioTracker 6.0 PPG sensor, consisting of five photodiodes and two LEDs, works alongside a barometric altimeter and temperature sensor to provide a comprehensive view of your physiological state. Daily utility is enhanced by a built-in microphone and speaker for Bluetooth calls, the Zepp Flow voice assistant, and Zepp Pay for contactless payments. A unique dual LED flashlight with white and red light, including SOS and Boost modes, provides extra safety during night activities. You can rely on the 540 mAh battery for up to 20 days of typical use, though this extends up to 99 hours in Extended Autonomy Mode. The watch connects via Bluetooth 5.3 and Wi-Fi to the Zepp App, supporting both Android 7.0 and iOS 14.0 or newer.
