Bottom line
The Apple Watch Ultra 4 isn’t really trying to be the Apple Watch for everybody.
It’s aimed at people who actually spend time outdoors, train for long periods, dive, hike, or simply don’t want to think about charging their watch every night.
For a casual user, a lot of what you’re paying for may sit unused.
For the right person, though, those extras can make a real difference.
So what are you paying extra for?
Both the Series 12 and Ultra 4 use Apple’s S11 chip, and both get the new Health Sensing System and Readiness features.
So the Ultra isn’t dramatically different because it has a completely different processor.
The biggest difference is what surrounds that processor.
Battery is the big story
The Ultra 4 is rated for around 50 hours of normal use and up to 84 hours in Low Power Mode.
That’s a completely different charging routine from the Series 12.
And if you’re doing a long hike, multi-day trip or endurance event, that extra battery isn’t just convenient. It can be the difference between having a working watch and having a very expensive piece of jewelry on your wrist.
Apple also says the Ultra 4 can track outdoor workouts for up to 45 hours.
Built for the outdoors
The Ultra 4 uses a titanium case, has 100m water resistance, and includes satellite communication features.
That’s where the Ultra starts making more sense.
If you regularly go somewhere without reliable cellular coverage, satellite communication can be a genuinely useful safety feature rather than something you use once for showing off to your friends.
Who should buy it?
- Divers
- Hikers
- Ultra-distance runners
- Outdoor enthusiasts
- People who hate charging every day
- Anyone who spends extended periods away from a charger
Who shouldn’t?
If most of your day involves checking messages, tracking steps, answering calls and occasionally recording a workout, you probably don’t need all the Ultra hardware.
The regular Series 12 is considerably easier to justify for that kind of use.
