Apple Watch Ultra 4: What Actually Changed
Four generations in, the Ultra is still the smartwatch built for people who actually leave the house. Here's what's new in the fourth version.
The Apple Watch Ultra line has always been the version built for people who actually use their watch outdoors, not just at a desk. Four generations in, that positioning hasn't changed. The specifics have.
A Familiar Formula, Sharpened
The original Ultra earned praise as a genuinely good first attempt at a rugged smartwatch, with an Action button that reviewers immediately wanted on the standard line, multi-band GPS, and a bigger screen that's easier to read mid-activity. The fourth generation builds directly on that foundation rather than reinventing it.
The headline change is battery life: the Ultra 4 runs for up to 50 hours per charge on a single battery, up from 42 hours on the Ultra 3, with roughly 18 hours available during outdoor workouts using GPS and continuous heart rate tracking, stretching to around 45 hours in extended low-power modes. Apple has also moved to a new S11 chip, and paired it with sharper heart rate sensors, a new Readiness score, a Health Age metric, and a step-tracking system that leans on machine learning to refine accuracy over time. On the software side, Apple has added Siri-driven features including Live Rewind, Sound Recognition alerts, and Siri Recap, which summarises missed conversations.
Why It Still Matters
Where most smartwatch updates are incremental, the Ultra's value has always been in what it lets you leave at home: dedicated GPS devices, separate dive computers, standalone fitness trackers. The mapping, compass and BackTrack-style navigation tools that defined earlier versions remain the reason serious outdoor users pick the Ultra over the standard Apple Watch.
Spec callout: Fourth-generation Ultra, released September 2026, multi-band GPS.
Price and Availability
Apple has held the price steady rather than using the upgrade as cover for an increase. The Ultra 4 is priced from US$799 in the United States, which converts to A$1,349 locally, matching what the Ultra 3 launched at. It comes in Black Titanium or Natural Titanium cases, paired with Alpine Loop, Trail Loop, Milanese Loop or Ocean Band options in a range of colours, with GPS plus Cellular included as standard across every model. Preorders opened on 9 September 2026, with the watch reaching stores and doorsteps from 18 September, and Apple's usual trade-in program is available for buyers upgrading from an earlier model.
Verdict
This isn't a watch that needs to reinvent itself every year, and Apple clearly knows it. The Ultra 4 is a refinement, not a reset, and for the audience it's built for, that's exactly the right call. For anyone already carrying an Ultra 3 comfortably through their weekends, the case to upgrade rests almost entirely on that extra battery runway, rather than anything flashier.
