The Apple Watch Series 12 combines a smaller screen with a larger body than the Series 10 and 11, although the pixel resolution hasn’t changed, according to Apple’s technical specifications.
For the 46mm Series 12, Apple’s tech specs page lists the display area at 1,196mm², down 2% from the 1,220mm² of the Series 10 and 11. The 42mm size has a similar drop of 1.9%, from 989mm² to 970mm². The number of pixels is identical across all three generations: 416 x 496 at 46 mm and 374 x 446 at 42 mm.
The case gets bigger as the screen shrinks. Apple’s Series 12 tech specs list the 46mm case at 46mm by 40mm by 9.7mm, a millimeter wider than the 46mm by 39mm by 9.7mm case of the Series 10 and 11, an increase of about 2.6 percent in case footprint. The 42mm case went from 42mm by 36mm to 42mm by 37mm over the same time, or about 2.8%, with depth unchanged at 9.7mm for both sizes.
A smaller screen combined with a larger body means larger bezels around the screen, and it looks like Apple has also changed the Series 12 design to move the case back and widen the front glass, making the bezels even bigger.
There is recent precedent for a change like this, which results in a visibly thicker bezel. The Series 10 saw a similar change when it replaced the Series 9 in 2024, making the case around the screen larger. The visible aluminum edge of the Series 10 has actually shrunk by around 33% compared to the Series 9, while the total bezel, including the black glass border, has increased by around 17%, although the case and screen numbers appear to be an improvement on paper.
It appears that the Series 12 repeats this pattern, although to a less extreme extent. Unlike the change from Series 9 to Series 10, which was a complete case redesign, Series 10, 11, and 12 all share the same rough case design. The Apple Watch Series 12 starts at $399 and launches September 18.
