Which one fits you
Both need much the same wrist — roughly 50–68mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Watch 2 and Watch 2 Pro share a near-identical 45.9mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Watch 2 feels lighter (36.8g vs 54.5g, case only).
The Watch 2 is thinner than 82% of the 203 46mm watches we hold thickness for, the Watch 2 Pro than 82% — so both wear flatter than their widths suggest.
The Watch 2 is 0.1mm shorter and 17.7g lighter than the Watch 2 Pro. Both are circular.
