Verdict: nothing you’d notice between them
On the makers’ published figures, neither the Apple Watch Series 10 42mm nor the Apple Watch Series 10 46mm wins a row by a gap you would notice. One gap is borderline, a difference most people would not notice: weight (case only) (30 g against 36.4 g) for the Apple Watch Series 10 42mm. Both state the same peak brightness, battery life (maker's claim) and charge to 80%. The other 24 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.
