Amazfit's flagship health watch pairs a Grade 5 titanium and sapphire build with a 780 mAh battery rated at up to 30 days, at $599.99.
Balance Ultra is the top model in Amazfit's Balance line, listed on the brand's US store at $599.99. The bezel, frame, buttons, and back cover are Grade 5 titanium over a fiber-reinforced polymer case, with sapphire glass covering a 1.5 inch AMOLED display rated at up to 3,000 nits peak brightness (480 x 480, 323 PPI). It weighs 57g without the strap and measures 15.5mm thick including the heart rate sensor module. Water resistance is 10 ATM, and the workout list includes recreational scuba diving and freediving to 45m.
The sensor stack is the BioTracker 6.0 PPG biometric sensor with 5 photodiodes and 2 LEDs, plus acceleration, gyroscope, ambient light, geomagnetic, temperature, and barometric altimeter sensors. Positioning uses a dual-band, circularly polarized antenna across 6 satellite systems. The 780 mAh battery is rated at up to 30 days of typical use, 15 days of heavy use, 10 days with the always-on display, and 50 hours in accuracy GPS mode. Those are Amazfit's own 'up to' figures; always-on display and frequent GPS tracking pull real-world numbers toward the lower ratings.
On the software side it runs Amazfit's HybridCharge energy readouts through the Zepp app, which is where all long-term health and training data lives. The spec sheet lists 180+ workout modes, HYROX Race and Simulation modes, base maps with turn-by-turn directions and route planning, golf course and ski resort maps, 64GB of storage, a red and white flashlight, and a mic and speaker for calls.
The honest trade-offs: the published sensor list is PPG-based, and ECG does not appear anywhere on the product page. You are also committing to the Zepp app rather than a larger third-party ecosystem. And within Amazfit's own lineup, the $299.99 Balance 2 shares the 1.5 inch AMOLED with sapphire glass and carries a 21-day typical battery rating, so the Ultra's extra $300 buys the titanium build, the larger 780 mAh battery, dual-band positioning, and the HYROX modes rather than a different health feature set.
Hybrid-training athletes who want a titanium, 10 ATM watch with multi-week battery ratings, dual-band GPS, and HYROX race modes without a daily charger.
You want ECG on the spec sheet, you live outside the Zepp app ecosystem, or the $299.99 Balance 2's same-size sapphire AMOLED and 21-day rating covers your tracking needs.
