Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 52mm, the Watch 4 Pro is the safer pick — it stays proportionate down to roughly 50mm, where the Watch 3 Pro starts to hang over the edge. Above 52mm both sit cleanly, and the Watch 3 Pro gives you more presence.
The Watch 3 Pro and Watch 4 Pro share a near-identical 48mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Watch 4 Pro is the slimmer of the two (12.9mm vs 14mm), so it slides under a cuff more easily.
On the wrist the Watch 3 Pro feels lighter (63g vs 65g, case only).
The Watch 3 Pro is thinner than 79% of the 43 48mm watches we hold thickness for, the Watch 4 Pro than 77% — so both wear flatter than their widths suggest.
The Watch 3 Pro is 0.4mm wider, 2mm longer, 1.1mm thicker and 2g lighter than the Watch 4 Pro. Both are circular.
