Buying advice

Which should you buy?

These two are nearly even on the Mars Score (60.5 vs 58.5). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Watch Ultra 2 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, display size, water resistance, among others.

Pick the Venu 4 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, weight.

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