Apple will unveil the Watch Series 9 and Watch Ultra 2 at its “Wonderlust” event today alongside the iPhone 15 series. Both smartwatches are said to be similar to their predecessors. A new report from Bloomberg now claims that these watches will use a new version of Apple’s optical heart rate sensor. So far, the third generation heart rate sensor is used in the Watch Series 8 and the Watch Ultra.


The Apple Watch Series 9 and Watch Ultra 2 also get various other sensor upgrades and new internal components. The focus is on speed, accuracy and efficiency. Additionally, Apple smartwatches, like the iPhone 15 series, will feature the new U2 Ultra Wideband chip for improved Find My features.
According to Bloomberg, another development focus this year is the performance of the Apple Watch, with the Cupertino-based tech giant planning to “heavily tout major gains in processing speed.” The hardware basis for this is provided by the new A15 Bionic chipset, which will power the Watch Series 9.
The Apple Watch Series 9 is offered in 41mm and 45mm sizes. The Watch Ultra 2 is expected to be made from more recycled materials. It might get a black color option, and be only sold in a single 49mm size. Apple is also testing 3D printed cases for the stainless steel Watch Series 9 models. The Ultra line should switch to 3D printing starting next year.
Additionally, Apple is reportedly ditching some of its leather straps and may update or discontinue its stainless steel link straps. We’ll know more as the day goes on.
