Which one fits you
Both need much the same wrist — roughly 44–61mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Watch and Watch 5 - 42mm share a near-identical 42mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Watch 5 - 42mm is the slimmer of the two (10.5mm vs 11.3mm), so it slides under a cuff more easily.
The Watch is thinner than 78% of the 661 42mm watches we hold thickness for, the Watch 5 - 42mm than 89% — so both wear flatter than their widths suggest.
The Watch is 0.5mm shorter and 0.8mm thicker than the Watch 5 - 42mm. Both are circular.
