Between the Watch Ultimate and Vantage V3, the Watch Ultimate comes out ahead in battery life and display size, while the Vantage V3 wins on weight. Overall, the Watch Ultimate scores 64.5 and the Vantage V3 scores 53.5 on our Mars Score.
Which should you buy?
The Watch Ultimate is the clear pick on raw spec strength, leading by 11.0 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 Vantage V3 if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight.
Both ship with comparable ecg, cellular, 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.
