Which one fits you
Both need much the same wrist — roughly 48–67mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Watch 5 - 46mm and Watch GT 3 - 45mm share a near-identical 46mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Watch GT 3 - 45mm feels lighter (42.6g vs 63g, case only).
The Watch 5 - 46mm is thinner than 83% of the 211 46mm watches we hold thickness for, the Watch GT 3 - 45mm than 91% — so both wear flatter than their widths suggest.
The Watch 5 - 46mm is 0.1mm wider, 0.8mm longer, 0.3mm thicker and 20.4g heavier than the Watch GT 3 - 45mm. Both are circular.
