Colours are vivid, blacks are deep, and the screen remains legible under bright sunlight. The AOD mode consumes ~0.8 mA, translating to roughly 5 hours of extra battery life versus a “screen‑off” watch.
The 400 × 400 resolution feels a tad low on a 1.4‑in screen compared with flagship competitors (e.g., 454 × 454 on the Galaxy Watch 6). Text isn’t razor‑sharp on the smallest UI elements, but the difference is minor for most users. 5.

Independent lab testing (by TechRadar Labs ) placed the Watch32 IS within ±3 bpm for HR and ±2 % for SpO₂, comparable to the Garmin Venu 2 and Apple Watch 8 . ECG waveforms are clean; the device flags abnormal rhythms with a 97 % true‑positive rate. 7.
