Apple Watch Ultra 2

A brighter screen and Double Tap. The Ultra 2 runs 3000 nits peak rather than 2000, which matters in direct sun on a mountain, and carries the S9 chip that brought the finger-tap gesture and on-device Siri working without a signal. That last part is the genuinely useful one for anyone out of coverage. Apple added a black titanium finish in 2024, the first color option the Ultra had ever been offered in. Everything else carried over unchanged: 49mm of titanium, 100 meter water resistance, dual-frequency GPS, the siren, the Action button and 36 hours of battery.
