If you think aIn the Health app on your iPhone, you can view a record of all your measurements and see graphs of your blood oxygen level readings for the day, week, month, or year. It also shows your range and daily average, and you can filter the data to show just your SpO2 level in high-elevation environments or while sleeping. Requires Apple Watch Series 7, SE, Ultra, or later. For a list of supported countries and regions, see apple.com/watchos/feature-availability. Apple defines its restrictions on harmful substances, including definitions for what Apple considers to be “free of”, in the Apple Regulated Substances Specification.

In the box with the watch, Apple includes a charging cable, but you don't get a USB power adapter. Apple says it made this decision to help the environment, and it will have the same impact as eliminating 50,000 cars from the roads. Design The standout feature here is a new sensor that can measure the oxygen saturation of your blood, also known as SpO2. This metric indicates how well your circulatory and respiratory systems are delivering oxygenated blood to your body. Your SpO2 reading alone can't diagnose COVID-19, but as the Yale School of Medicine advises, a reading below 90 percent may warrant a trip to the emergency room. The watch offers information about this metric to help you interpret your data. It says that most people have a blood oxygen level between 95 and 100 percent. The first time I used this feature, the Series 6 said my blood oxygen saturation level was 99 percent. The second time I took a reading, it was after a three-mile beach run, and I was happy to see my SpO2 level was 100 percent. Apple Watch Series 9 has a water resistance rating of 50 meters under ISO standard 22810:2010. This means that it may be used for shallow-water activities like swimming in a pool or ocean. However, Apple Watch Series 9 should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth. Water resistance is not a permanent condition and can diminish over time. For additional information see support.apple.com/en-us/HT205000.
