As an update to its Apple Watch Design resources, the company has now provided official bezel mock-ups of the 38 mm and 42 mm watches. Although the files are meant for developers, readers interested in Apple Watch can also use the images to compare the overall physical size of the two sizes.
The templates also accurately show how large the Watch bezels are, in relation to the screen. As the bezels remain the same size, they take up a larger proportion of the 38mm’s face than the 42 mm size. You can see the two Apple Watch styles overlaid below: the 42 mm watch is colored blue (or deep violet depending on your display).
