The Apple Watch Series 10 is rumored to gain larger display sizes and a thinner case design when it launches later this year, according to the reliable analyst Ming-Chi Kuo.

In a new post on Medium today, Kuo says that the upcoming Apple Watch generation is set to be redesigned with several form factor changes. More specifically, Apple Watch Series 10 will gain bigger display options that will measure 49mm and 45mm compared to the 45mm and 41mm sizes offered today with the Series 9 generation and earlier.

Apple last increased the size of the Watch with the Series 7, slightly growing from 44mm and 40mm on the Series 6 to 45mm and 41mm thanks to smaller bezels. If the rumors are correct, the bigger Series 10 model will have the same screen size as the Apple Watch Ultra, while the smaller size will have the same screen area as the larger Series 9 today.

Beyond the new screen sizes, the Apple Watch Series 10 is said to gain a slimmer case design. Kuo declines to mention the expected thickness of the new housing, yet it could be significantly thinner than the Series 9 if Apple is moving ahead with its new strategy of making super-thin products like the M4 iPad Pro.

For the Apple Watch Ultra, Kuo does not expect significant changes, save for a new darker color option in addition to today’s natural titanium finish. 3D-printed mechanical parts, a rumor that circulated last year, are now expected to make their way to certain Apple Watch models during the second half of 2024. Apple originally planned to use 3D-printed parts last year, but production snags prevented the company from doing so. Production efficiency has dramatically improved over the past year, and 3D parts are finally set to make their way to commercial units.

Beyond design changes, Apple Watch Series 10 and Ultra 3 are expected to gain a new blood pressure sensor. A non-invasive blood glucose monitor is not expected to debut on the Apple Watch till the end of this decade.
