GoKawiilApple Watch Series 12 brings back Ceramic case and new health sensor array
Apple's Series 12 keeps the same screen size and case dimensions as the Series 11 but adds a returning Ceramic case option in white or blue, Ceramic Shield 2 on aluminum models, and new color choices including dark bronze and radiant gold. The bigger change is an overhauled 'health sensing system' with a larger skin-contact area and more diodes, electrodes and sensors packed into the same footprint.
