Huawei - Watch Ultimate vs Google - Pixel Watch 3 (45mm)

The Watch Ultimate is the clear pick on raw spec strength, leading by 17.8 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the Watch Ultimate if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are battery life, display size, water resistance.

Pick the Pixel Watch 3 (45mm) if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are peak brightness, weight, cellular.

Both ship with comparable ecg, spo2, so those specs don't separate the two — focus on the differences below.

Bottom line: the Watch Ultimate is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
