Which one fits you
Both need much the same wrist — roughly 51–70mm 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 (2018) share a near-identical 45mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Watch 2 is thinner than 70% of the 386 45mm watches we hold thickness for, the Watch 2 (2018) than 70% — so both wear flatter than their widths suggest.
The Watch 2 is 0.6mm shorter than the Watch 2 (2018). Both are circular.
