Will Apple Watch 9 have blood pressure monitor?

As of the search results provided, the Apple Watch Series 9 (released before 2024) does not have a built-in blood pressure monitor. Users can pair compatible external blood pressure monitors with their Apple Watch Series 9 to collect and track data utilizing third-party apps and Apple Health integrations.

However, rumored plans for future versions indicate that the Apple Watch Series X (potentially released in 2024), which commemorates the anniversary of the initial Apple Watch release, could include blood pressure detection technology. This innovative capability would distinguish future Apple Watch models from existing ones, allowing for blood pressure monitoring without additional accessories. It should be noted, however, that this remains a rumor until officially confirmed by Apple during its traditional product announcement events.
