Apple Watch Ultra

Apple's biggest watch: titanium case, brighter screen, more than a day of battery

Titanium, big, and built to run for more than a day between charges. It logs workouts, heart rate and sleep exactly as the standard Apple Watch models do. The extra size buys endurance and a brighter screen, not new sensors. That is what matters for sleep tracking. People who want sleep data from an Apple Watch usually end up here, because the smaller models need charging too often to stay on overnight.
