The Cheetah 2 Ultra is Amazfit's answer to a specific kind of runner: the one who signs up for 50 miles because 31 miles felt too short. It's a trail-focused, ultra-distance GPS watch that sits above the Cheetah 2 Pro in the lineup, and while it shares most of the same core hardware, it pushes the specs that matter when you're out there for six, eight, twelve hours at a stretch.
I've been digging into the spec sheets, press materials, and early coverage to put together a full picture of what the Ultra actually is, and who it's built for.
What's New With the Ultra
The Cheetah 2 Ultra launched in May 2026 as the endurance-focused sibling to the Cheetah 2 Pro. Where the Pro targets the marathon road runner, the Ultra is unmistakably aimed at trail runners and ultra-distance athletes. That shows up in three areas that matter most: display size, battery capacity, and storage.
The display jumps from the Pro's 1.32 inches to 1.5 inches. That's a meaningful bump for a watch you'll be glancing at on technical terrain. More real estate means more workout data visible at a glance without breaking stride. The Ultra keeps the same 3,000-nit peak brightness as the Pro, so sunlight readability stays excellent. Resolution drops slightly (480x480 vs 466x466) but at 323 PPI, you're not going to notice any pixelation on a display this size.
Battery is the headline feature. The Ultra delivers up to 33 hours in Trail Running mode. Enough to cover most 50K and 50-mile races without reaching for a battery pack. Typical daily use is rated at 30 days, which is in line with what you'd expect from the Pro. If you're a runner who races ultras, or trains for hours at a time in demanding terrain, this is the number that matters.
Storage jumps from 32GB to 64GB. That gives you room for full offline contour maps, route files, music, and whatever else you want to load on without having to pick and choose. For a trail watch, this is the right call. You want navigation on the wrist when cell signal disappears.
Build Quality: Titanium Throughout, No Compromises
The Ultra goes beyond the Pro in build quality. Both watches use a Grade 5 titanium frame and case, but the Ultra takes it further with a titanium bezel and titanium buttons. The Pro uses a plastic bezel and aluminum alloy buttons, which keeps its price down but gives the Ultra a clear edge in material quality for trail and ultra use.
Sapphire glass protects the 1.5-inch AMOLED display on the Ultra, same as the Pro. The titanium construction means the Ultra can take the kind of abuse that trail running dishes out without showing it. The wider 22mm strap (vs the Pro's 20mm) helps distribute pressure more evenly over long efforts and stays more secure on technical terrain.
Running Features: Everything the Pro Has, Plus a Little More
The Ultra runs the same BioTracker 6.0 PPG sensor as the Pro (5PD and 2LED), which tracks heart rate, blood oxygen, HRV, and sleep. Both watches also share the same dual-band GPS with support for six satellite systems, which should give you solid accuracy even under tree cover or in steep canyons.
What the Ultra adds:
- Trail Running mode with load factor calculations. This factors in gradient, terrain resistance, and vertical gain so your effort data actually reflects what your body experiences on the trail (not just flat road pace).
- Color-coded elevation overview across your entire route.
- Larger screen for workout pages, maps, and data fields during outdoor sessions.
Both watches share the same training ecosystem: Zepp Coach AI for adaptive training plans (5K to marathon), structured workouts from TrainingPeaks, Runna, and Intervals.icu, and automatic Strava sync. If you're already in that ecosystem, the Ultra isn't asking you to change anything. It's just giving you more screen to work with.
Navigation and Maps
This is where the Ultra pulls ahead of the Pro. Full-color contour maps, turn-by-turn navigation, automatic rerouting if you go off-course, and points of interest search all come standard. With 64GB of storage, you can load regional map packs and have them ready when you're off-grid.
Route planning from the watch itself is a nice touch. Set a target distance and direction and the watch generates optimized round-trip routes. That's genuinely useful for exploring new trail systems without pre-planning on a computer.
Battery Deep Dive
Here's the full picture on battery life:
| Mode | Cheetah 2 Ultra | Cheetah 2 Pro |
|---|---|---|
| Trail Running (GPS) | 33 hours | 31 hours |
| Typical Daily Use | 30 days | 20 days |
| Precision GPS | ~26 hours | ~24 hours |
The Ultra's 780 mAh battery (vs the Pro's 540 mAh) is the key difference. Two extra hours of trail GPS might not sound like much on paper, but in a 50-mile race or a big training day in the mountains, it could be the difference between finishing with data and finishing blind.
Display and Brightness
Both watches max out at 3,000 nits, which is genuinely impressive for a GPS watch. Most Garmin devices sit in the 1,000-2,000 nit range. Alpine starts and late-evening runs won't be a problem for readability. The jump to 1.5 inches on the Ultra is the real differentiator here, especially if you're someone who runs with multiple data pages or relies on maps during navigation.
Who Should Buy the Ultra?
The Cheetah 2 Ultra is built for:
- Ultrarunners and trail runners who measure efforts in hours, not miles.
- Athletes who race or train in remote terrain where offline maps and navigation are essential.
- Runners who want the biggest possible display for data-heavy training pages or map navigation.
- Anyone who needs maximum storage for maps, music, and route files.
If you're primarily a road runner, training for a marathon or shorter distances, the Cheetah 2 Pro at $150 less is the smarter call. You get almost all the same sensor tech, GPS accuracy, and training ecosystem in a lighter package. The Ultra's extra battery and screen are overkill for sub-4 hour race efforts.
Price and Availability
$599.99 is available now on the Amazfit website and major retailers. The Ultra is priced $150 above the Cheetah 2 Pro, which puts it in direct competition with Garmin's entry-level Fenix devices for runners who want premium build quality without the Garmin premium.
