iFixit has already begun its expected teardown of Apple Watch, this time posting the results in real-time as the site proceeds through each step. While the teardown is still ongoing, iFixit has already made some interesting observations by examining the innards of Apple’s new wearable device, including the nature of the device’s construction, how tightly integrated and packed in the circuitry is, and the likely proprietary nature of the inductive charging system. Notably, iFixit also reports that the heart rate monitor in the device is “actually a plethysmograph,” suggesting that it can be used as a pulse oximeter, despite Apple not advertising this feature; the report speculates that this may be due to FDA regulations on health monitoring devices. After finishing up with the Sport Edition, iFixit has now begun tearing down the Stainless Steel model, and is promising to report back later with more details on that one.
