Redesigned means it looks significantly different from Series 9, unlike Series 8 and Series 7 which are very similar. A slightly larger screen also doesn’t qualify as redesigned.

Bloomberg's Mark Gurman expectes a "redesign" with Apple Watch 10 being thinner and having different magnetic band attachments. I'm thinking if it's visually apparent this would be significant enough?
At least one Apple Watch model will feature an updated look, and while Gurman does not specify, it could be the standard Apple Watch that's getting a design update. Apple just introduced the Apple Watch Ultra in 2022, and while there are rumors of a larger microLED display for that device, current information suggests Apple won't be ready to add microLED until 2025 or 2026.
This sounds fairly wishy-washy
@mattyb no doubt, it's very wishy-washy. It still seems like the most accurate current expectations I could find. I have seen others place greater emphasis on the fact that a new Ultra wouldn't make sense this year but a 10th anniversary watch redesign does. (it's also possible that it wouldn't come until 2025 but it seems more likely this fall)
