Verdict: Apple Watch Series 9 41mm ahead on 1 row, Apple Watch Series 7 41mm on none
On the makers’ published figures, the Apple Watch Series 9 41mm wins on peak brightness (2,000 nits against 1,000 nits). The difference in weight (case only) is below the threshold you would notice. Both state the same case size and battery life (maker's claim). The other 25 rows have no threshold or no direction to judge by, so nobody wins them.
True to scale
Case outlines from each maker’s published dimensions, drawn to scale. Corner rounding is our drawing convention, not a measurement.
Specifications
A win is marked only where the figures can be ranked and the gap is one you could notice on the wrist. A row the site has no threshold for says whether the two differ, and that it is not ranking them. = marks the same figure on both, ≠ not ranked a difference with no ranking. Every figure carries its source.
