Apple - Watch SE 3 vs Samsung - Galaxy Watch 7 Pro

The Watch SE 3 edges ahead on the Mars Score (56.1 vs 51.9), but the 4.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Watch SE 3 if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, display size.

Pick the Galaxy Watch 7 Pro 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, peak brightness, water resistance, among others.

Both ship with comparable cellular, 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.
