Apple is reportedly testing its September 2026 Apple Watch lineup, but the new models are expected to be minor updates while more substantial changes are much further off.

The sensors on the back of the Apple Watch Ultra 3
Most recent rumors have claimed that the forthcoming Apple Watch Series 12 will not feature any hardware improvements over its predecessor. Now backing up those reports, Bloomberg says that neither the Apple Watch Series 12 nor the expected Apple Watch Ultra 4 will get visible upgrades to their design.
Instead, the updates will be concentrated on giving the new Apple Watches a significant performance boost through a new processor. There may also be health and fitness tracking improvements, though previous reports have claimed that there won’t be new sensors, so this may be a software update.
