Which one fits you
On wrists narrower than about 51mm, the Watch GT 5 Pro 42 mm is the safer pick — it stays proportionate down to roughly 45mm, where the Watch Ultimate 2 starts to hang over the edge. Above 51mm both sit cleanly, and the Watch Ultimate 2 gives you more presence.
The Watch Ultimate 2 wears larger than the Watch GT 5 Pro 42 mm (48.5mm 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 12.9mm), so it slides under a cuff more easily.
On the wrist the Watch GT 5 Pro 42 mm feels lighter (44g vs 80.5g, case only).
The Watch GT 5 Pro 42 mm is thinner than 92% of the 43mm watches we track and the Watch Ultimate 2 than 75% of the 49mm ones — so both wear flatter than their widths suggest.
The Watch Ultimate 2 is 6mm wider, 6mm longer, 3.3mm thicker and 36.5g heavier than the Watch GT 5 Pro 42 mm. Both are circular.
