Apple will host its highly anticipated Wonderlust event on Tuesday where it will see fit to announce the new Apple Watch models and the iPhone 15 lineup. While details on the Apple Watch Series 9 and Apple Watch Ultra 2 were scarce, a prominent analyst has now shared last-minute information on new health sensors and internals and design.

The last-minute details were shared by Bloomberg’s Mark Gurman, suggesting that the forthcoming Apple Watch Series 9 and Apple Watch Ultra 2 will come with a new heart rate monitor and upgraded sensors. The analyst highlights what he expects Apple to announce at its highly anticipated event. It was previously rumored that the Apple Watch Series 9 would feature the same design as the Series 8 but will come with a new S9 chip and a pink color option. As for the Apple Watch Ultra 2, Apple will introduce a dark gray titanium finish.

The analyst mentions that both variants of the Apple Watch will come with new sensors and numerous component upgrades. He also says Apple’s focus this year for the Apple Watch is speed, accuracy, and efficiency. To fulfill its ambitions, the company will introduce a new optical heart rate sensor in the Apple Watch Series 9 and Apple Watch Ultra 2. The company will also upgrade existing sensors which will allow for more accurate reading of health metrics. This is the first time that we are hearing details on the new sensors for Series 9 ahead of its announcement next week.
