The Amazfit Balance Ultra is the most expensive watch Amazfit has ever made, and it lands with a question attached: is $599.99 justified?
The spec sheet says yes. Grade 5 titanium, sapphire glass, a 3,000-nit AMOLED, 30 days of battery, and 50 hours of continuous GPS. But since we covered the launch in June, a month's worth of real-world usage reports has come in, and the picture is more interesting than the press release. Here's the full rundown.
If you're already torn between this and the cheaper Balance 3, our Balance Ultra vs Balance 3 head-to-head has the side-by-side. This one is about the Ultra on its own terms.
Build: Premium That You Can Actually Feel
The Balance Ultra is a big watch. The case measures 51.8 x 51.8mm, and at 57g without a strap, it has real presence. Early wearers with wrists around 7 inches report it completely engulfing the wrist, though the titanium keeps it lighter than it looks, and comfort over multiple days is a non-issue.
The materials are the point here. Grade 5 titanium for the bezel, frame, buttons, and back cover. Sapphire glass over the display. Both are the same materials Garmin uses on the Fenix 8 and Apple uses on the Watch Ultra 2, and at $599.99, they should be.
Details that stand out in daily use:
- Five physical buttons, all titanium. Three on the left (notifications, LifeLoad health log, Zepp Flow AI assistant), a crown that opens workout modes, and a right-side button for back/app access. Buttons matter when your hands are sweaty mid-set.
- A dual-color flashlight, red and white. Small thing, genuinely useful for early morning starts.
- 10 ATM water resistance with freediving support to 45m and recreational scuba modes. Rare on a running-focused watch.
- 64GB of storage for offline maps, music, and route files.
Display: The Brightest in the Lineup
The 1.5-inch AMOLED peaks at 3,000 nits with sapphire protection. That's brighter than almost anything Garmin sells (most sit between 1,000 and 2,000 nits), and it's the same panel spec as the Balance 3. In direct sunlight, readability is excellent, and the extra real estate helps with data-heavy training screens and map navigation.
Battery: Claimed vs. Reality
Amazfit's battery claims for the Ultra are aggressive:
| Mode | Claimed |
|---|---|
| Typical use | Up to 30 days |
| Heavy use | Up to 15 days |
| Always-On Display | Up to 10 days |
| High-accuracy GPS | Up to 50 hours |
| Power-saving GPS | Up to 97 hours |
Real-world reports are landing close to those numbers. One month-long test with Always-On Display enabled (a battery killer on any watch) averaged about 10 days per charge on the 780 mAh cell, with a mix of running, walking, and gym sessions. That matches the AOD claim almost exactly, which is a good sign. Without AOD, expect to stretch toward two weeks or more.
The 50-hour GPS figure matters if you race ultramarathons or spend long days in the mountains. It beats most Garmin watches in this price range, which typically sit in the 30-40 hour band.
GPS and Training Accuracy
The Ultra uses dual-band GPS across six satellite systems, paired with the new BioTracker 6.0 optical sensor (5 photodiodes, 2 LEDs). Month-long testing found GPS paths, distance, and pace to be spot-on against known routes, with run data covering cadence, ground contact time, stride, and per-mile splits.
Where the Ultra shows its limits is strength training. Rep counting and muscle targeting are hit or miss. One extended test logged a full-body dumbbell session as 119 overhead triceps extensions. This is a weakness shared across nearly every smartwatch, Amazfit included, but if accurate lifting analytics are your priority, know this going in.
Sleep tracking reads accurately: duration, stages, respiratory rate, resting heart rate, and daily insights with improvement tips. Stress and recovery tracking feed into the HybridCharge system described below.
The Hybrid Training System
The Balance Ultra runs Zepp OS 6 with Amazfit's Hybrid Training System, built around one idea: you don't train in neat single-sport blocks, so your watch shouldn't score you that way either.
HybridCharge combines three signals into one readiness picture:
- BioCharge: daily energy based on HRV, sleep, stress, and recovery
- LifeLoad: cumulative strain from training plus everyday life
- Training Load: strain from structured workouts
The practical payoff is the "should I push today or recover" answer before you lace up. Supporting tools include Weekly Focus, Training Balance across strength/endurance/recovery, and hybrid plans that mix running with lifting.
And because Amazfit is the official wearable partner of HYROX, the Ultra includes HYROX training plans, race simulations, virtual pacing for run-workout intervals, and per-station post-race analytics. If you race HYROX, no other brand has invested this deeply in the format. Our Balance 3 and Ultra launch coverage goes deeper on the whole system.
Balance Ultra vs Cheetah 2 Ultra: The Same-Money Question
Here's the comparison most buyers actually need. The Balance Ultra and the Cheetah 2 Ultra both cost $599.99. Which one you want depends on how you train:
- Cheetah 2 Ultra is the pure running watch. Trail-focused navigation, lighter priorities for road and trail racing, and the running-first feature set. If 90% of your workouts are running, this is the one. Our Cheetah 2 Pro vs Ultra breakdown covers that family.
- Balance Ultra is the hybrid athlete's watch. Same-tier display and GPS, but adds the Hybrid Training System, HYROX tools, strength programming, diving modes, and a bigger 780 mAh battery. If your week mixes running, lifting, and functional fitness, the Balance Ultra is built for exactly that schedule.
Same price, different jobs.
Who Should Buy the Balance Ultra?
Buy it if you're:
- A hybrid athlete mixing running, lifting, and functional fitness most weeks
- A HYROX competitor who wants race-specific tooling
- An ultrarunner or adventure racer who needs 50+ hours of GPS
- Someone coming from a Fenix or Apple Watch Ultra who wants the same build quality for less
Skip it if:
- You mostly run. The Cheetah 2 Ultra does that job at the same price, and the Balance 3 handles it for $230 less.
- You want 90% of this experience at a smarter price. The Balance 3 shares the display, GPS, and Hybrid Training System at $369.99.
Bottom Line
The Balance Ultra is Amazfit's statement watch, and for the first time, the statement mostly holds up. Titanium and sapphire at $599 undercuts the Apple Watch Ultra 2 by $200 while matching Garmin's flagship materials. Real-world battery results are tracking close to the claims, GPS accuracy reports are strong, and the Hybrid Training System is a genuinely different take on readiness that Garmin hasn't copied.
The caveats are real too. It's a large watch, strength rep counting is unreliable, and the software ecosystem is still thinner than Garmin's for niche sports. But for the hybrid athlete it's built for, the Balance Ultra is the most convincing premium Amazfit yet.
This review draws on Amazfit's official specs and early extended-use reports from third-party testers. Long-term testing from our own wrists will follow in a future update.
