Apple Watch Series 9 and Ultra 2 to Lose Blood Oxygen Monitoring Feature

New Units to be Manufactured Without the Feature Amid Patent Dispute

Apple Watch Series 9 and Ultra 2 will be sold without the blood oxygen monitoring feature due to a patent dispute with medical technology company Masimo.
The ban on the blood oxygen monitoring feature only affects new sales and imports of the Apple Watch Series 9 and Ultra 2 models.
Apple Watches that have already been sold, including those with the blood oxygen sensor, will continue to function as normal.
Apple has begun manufacturing new units without the blood oxygen monitoring feature and restocking older models will cease.
Customers outside of the United States will still have access to the feature in both old and newer models.
