  • Always-On Display Mode: Each model supports a mode where essential information remains visible without wrist movement. This is useful during workouts and daily use when users want quick glances without activating the main screen.
  • ECG: Both devices include an ECG sensor for detecting atrial fibrillation signs. This allows users to easily record heart rhythm data and share it with healthcare providers if needed.
  • SpO2 Blood Oxygen Tracking: Both track blood oxygen levels during sleep and throughout the day. Monitoring oxygen saturation helps detect breathing irregularities and general wellness trends.
  • Skin Temperature Tracking: Each watch can measure variations in skin temperature while sleeping. These fluctuations can provide early insights into illness, stress, or menstrual cycle changes.
  • GPS + GLONASS: Both models use built-in GPS for accurate route tracking during outdoor exercise. This means users do not need to bring their phone for walking, running, or cycling sessions.
  • Heart Rate Sensor: The watches offer continuous heart-rate monitoring with zone guidance during workouts. This supports better exercise performance and daily health insights.
  • Sleep Tracking: Each model tracks sleep stages including light, deep, and REM sleep. This helps users improve rest habits and understand recovery.
  • Menstrual Cycle Tracking: Both include features for logging cycles and predicting fertile windows. This supports those who want better cycle awareness and long-term health tracking.
  • Swim-proof 50m: Both watches are safe for showering, swimming, and pool workouts thanks to 5ATM water resistance. Users can track swim sessions without worry.
