Blood oxygen: new sensor, new insights

• Take on-demand readings of your blood oxygen as well as background readings, day and night; your blood oxygen level is a key indicator of your overall wellness, and can help you understand how well your body is absorbing oxygen and the amount of oxygen delivered to your body
• Blood oxygen sensor is made up of four LED clusters and four photodiodes; incorporated into the completely redesigned back crystal, this new sensor works with the Blood Oxygen app to determine your blood oxygen level
• Green, red, and infrared LEDs shine light onto the blood vessels in your wrist, and photodiodes measure the amount of light reflected back; advanced algorithms then calculate the color of your blood, which indicates the amount of oxygen present

ECG and sleep tracking

• With the ECG app, Apple Watch Series 6 is capable of generating an ECG similar to a single-lead electrocardiogram, which can provide critical data for doctors and peace of mind for you
• Electrodes built into the Digital Crown and the back crystal work together with the ECG app to read your heart's electrical signals; it can indicate whether your heart rhythm shows signs of atrial fibrillation (a serious form of irregular heart rhythm) or sinus rhythm, which means your heart is beating in a normal pattern
• Getting the right amount of sleep is important for good health, so the new Sleep app helps you establish a regular bedtime routine and keep track of your sleep trends night after night

Always-on access

• Always-On Retina LTPO OLED display is easy to read at a glance
• The Always-On Retina display is now 2.5 times brighter outdoors when your wrist is down, so even while exercising in bright sun, you can easily see your metrics without raising your wrist or breaking your stride
