Apple Watch Series 10 Prototype With Unique Health Sensor Revealed

Today, @StellaFudge posted images purportedly depicting an Apple Watch Series 10 prototype featuring a novel health sensor configuration.

The prototype's health sensor incorporates a smaller LED array than the Apple Watch Series 10 models released last year. An additional perimeter light ring is present; however, its functionality remains undetermined.

According to @StellaFudge, the prototype utilized an unreleased internal build of watchOS 11.1.

The Apple Watch's rear-mounted health sensor facilitates heart rate monitoring and, in international models (excluding the United States due to patent litigation), blood oxygen measurement. The prototype's sensor deviates visually; however, these alterations likely reflect Apple's ongoing exploration of future health-related features for the Apple Watch. For instance, Apple is reportedly investigating a high blood pressure alert function, initially rumored years prior to the Series 10 launch, but which continues to present developmental challenges. The feature's inclusion in the Apple Watch Series 11 remains uncertain.
