Samsung - Galaxy Watch 6 Classic vs Huawei - Watch Ultimate

The Watch Ultimate edges ahead on the Mars Score (66.8 vs 71.5), but the 4.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Galaxy Watch 6 Classic if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are peak brightness, weight, cellular. The single most decisive one: Peak brightness — 100.00% more. 2000 nits vs 1000 nits.

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. Its strongest claims are battery life, water resistance, display size. The single most decisive one: Battery life — 740.00% more. 336 h vs 40 h.

Both ship with comparable ecg, spo2, so those specs do not separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
