Buying advice

Which should you buy?

These two are nearly even on the Mars Score (60.5 vs 62). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Watch Series 11 (45mm) 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, weight, among others.

Pick the Venu 3 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.

Both ship with comparable ecg, spo2, water resistance, so those specs don't 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 tells you both are well-rounded; the differences are about trade-offs, not quality.
