No new clinically approved health sensor arrived for the Apple Watch Series 10, and as much as the company would have wanted the tenth iteration of its wearable lineup to launch with something memorable, technological and developmental hurdles prevented these new features from materializing. However, a prototype of Apple’s current-generation smartwatch family has shown up, with leaked images revealing that the Apple Watch Series 10 could have shipped with a new health sensor, but this addition did not make the final cut.
The latest pictures show that the Apple Watch Series 10 prototype features a unique health sensor arrangement, with an extra ring light around the perimeter
Compared to the Apple Watch Series 9, the Apple Watch Series 10 only offered a slightly bigger display and a thinner chassis, but there was a possibility that an aesthetics change was not the only differentiating factor between the two models, as there could have been another health sensor that becomes a part of the specifications. Sadly, it was not to be, but thanks to @StellaFudge, we get a closer look at what could have been the commercial unit of the Apple Watch Series 10 thanks to the latest leak.
While the exact nature of the health sensor is yet to be determined, the images show that there was a large circle present at the back for monitoring the wearer’s pulse, but the arrangement of those sensors has not only changed but their size has been reduced too, with an extra light ring present around the perimeter. The tipster mentions that the Apple Watch Series 10 prototype is running an unreleased build of watchOS11, making it next to impossible to test the sensor’s nature.
Prototype Apple Watch Series 10 with… A very unique health sensor arrangement.
The health sensors got shrunk down a lot and there was an extra light ring around the perimeter. The watch is also running an unreleased build of watchOS11, somewhere between 11.1b5 and 11.1rc. pic.twitter.com/8n06JkQT39

Furthermore, the stock apps that can determine the sensor’s functionality cannot be installed on the device as these programs can only be pulled from Apple’s internal network servers. The person cannot confirm what this hardware can do but has a hunch that it is a test platform for blood sugar. Sadly, we reported yesterday that Apple is still years away from bringing non-invasive blood glucose monitoring to its smartwatches despite having hit major milestones in the development phase. If @StellaFudge’s guess is correct, this might have been the elusive sensor we have heard about for years but never made it to the mass production chain.
