The Apple Watch 13 in 2027 is rumored to be the first model to feature blood sugar monitoring, which Apple has rumored to be working on for years.

Even back with the Apple Watch Series 7 in 2021, there were reports that Apple had long been developing a blood sugar system that was then about to be launched. Nothing came of that, and in 2024 Apple was said to be trialing such an Apple Watch app, but for health data collection studies rather than public release.
Now analyst Jeff Pu has announced that blood sugar monitoring will be the key feature of the Apple Watch Series 13 in 2027. He suggests that it may be called "Apple Watch featuring Blood Monitoring," but offers no further details.
As reported on , Pu has solely listed dates for this feature. There is no indication of whether this comes from supply chain sources, or is an extrapolation based on Pu's previous reports about Apple.
Note that those previous reports have included correct information at times. Pu does, though, also have a history of declaring release schedules that tend to be wrong.
Apple has been consistently working to add health features to Apple Watch, and a notable one was blood oxygen level monitoring. However, that technology has been the subject of a patent dispute and is currently disabled on Apple Watches sold in the US.
Separately, Apple is far from the only company attempting to produce a blood sugar monitoring system that is non-invasive. In January 2025, PreEvnt previewed a clip-on device that works via breath analysis.
