Amazfit Balance Ultra

Amazfit Balance Ultra is a watch from 2026, sitting in the flagship band at an indicative $599.

It reads 18 of the 33 signals this comparison tracks. Full coverage of activity. Nothing at all from body composition.

By sensor class: 10 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor, an optical blood oxygen sensor, a skin temperature sensor, a GPS receiver, a barometer and an accelerometer. Blood oxygen is a spot reading you take yourself, not a continuous one.

Its 30 days per charge are the 5th longest of the 76 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Multi-band GPS. Rated 10ATM / 100m, fine for swimming. It weighs 57 g. On top of the tracking it also handles music on the device and offline maps. Case size 51.8mm. No subscription is required.

June 2026 flagship above the Balance line. Titanium, sapphire, offline maps. No ECG and no bioimpedance body composition.
