Getting Pulse Oximeter Reading

You can manually begin a pulse oximeter reading by viewing the pulse oximeter glance. The glance displays your most recent blood oxygen saturation percentage.

  1. While you are sitting or inactive, press UP or DOWN to view the pulse oximeter glance.
  2. Press GPS to view glance details and begin a pulse oximeter reading.
  3. Remain motionless for up to 30 seconds.
    NOTE: If you are too active for the watch to get a pulse oximeter reading, a message appears instead of a percentage. You can check again after several minutes of inactivity. For best results, hold the arm wearing the watch at heart level while the watch reads your blood oxygen saturation.
