Leaked Apple Watch Ultra 4 Points to a Substantial Upgrade

The Apple Watch Ultra 4 is rumored to launch in September alongside the iPhone 18 Pro.

Expected upgrades include a thinner, more comfortable design, a better display, and improved battery efficiency.

Apple may add more advanced health sensing, possibly including blood pressure monitoring.
