Blood oxygen monitoring is returning to the Apple Watch — sort of. Apple’s announcement states that US customs has ruled that the company will be able to import watches with this redesigned feature. This redesign only covers Apple Watches sold after January 17th, 2024, once the ITC import ban took full effect. It doesn’t impact models sold before that date or watches sold outside the US, all of which still have the original blood oxygen feature. Apple has also lodged suits against Masimo over its smartwatches, which it claims are Apple Watch clones.
