Verdict: Apple Watch SE 3 44mm ahead on 1 row, Apple Watch SE 2 44mm on none
On the makers’ published figures, the Apple Watch SE 3 44mm wins on charge to 80% (45 min against 90 min). Both state the same case size, weight (case only), peak brightness and battery life (maker's claim). 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.
