Which one fits you
On wrists narrower than about 48mm, the Watch GT 5 Pro 42 mm is the safer pick — it stays proportionate down to roughly 45mm, where the Watch GT 6 - 46mm starts to hang over the edge. Above 48mm both sit cleanly, and the Watch GT 6 - 46mm gives you more presence.
The Watch GT 6 - 46mm wears larger than the Watch GT 5 Pro 42 mm (46mm vs 42.5mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Watch GT 5 Pro 42 mm is the slimmer of the two (9.6mm vs 11mm), so it slides under a cuff more easily.
On the wrist the Watch GT 5 Pro 42 mm feels lighter (44g vs 51.3g, case only).
The Watch GT 5 Pro 42 mm is thinner than 92% of the 43mm watches we track and the Watch GT 6 - 46mm than 88% of the 46mm ones — so both wear flatter than their widths suggest.
The Watch GT 6 - 46mm is 3.5mm wider, 3.5mm longer, 1.4mm thicker and 7.3g heavier than the Watch GT 5 Pro 42 mm. Both are circular.
