Display
1.64-inch AMOLED, 280 × 456 pixels, ~326 ppi. Curved/glass is 2.5D; good sharpness and quite readable.
Sensors / Tracking
Heart rate sensor; SpO2 (blood oxygen) sensor; Sleep tracking (light / deep / REM); Stress & breathing; over 110 fitness / sport modes; GPS (built-in dual-band GNSS) for tracking without needing phone in many situations.
Water Resistance
Rated 5 ATM (so safe for swimming, etc., but not for deep-diving) .
Battery & Charging
Battery capacity ~235 mAh. Typical usage (no always-on display, moderate tracking) claimed up to ~12 days. With heavier usage (AOD on, frequent GPS, continuous tracking) this drops significantly (around 3-4 days in some tests). Full charge in around 1 hour.
