Which one fits you
On wrists narrower than about 51mm, the Watch GT 5 is the safer pick — it stays proportionate down to roughly 48mm, where the Watch 2 (2018) starts to hang over the edge. Above 51mm both sit cleanly, and the Watch 2 (2018) gives you more presence.
The Watch GT 5 wears larger than the Watch 2 (2018) (45.8mm vs 45mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Watch GT 5 is the slimmer of the two (10.7mm vs 12.6mm), so it slides under a cuff more easily.
On the wrist the Watch GT 5 feels lighter (48g vs 57g, case only).
The Watch 2 (2018) is thinner than 70% of the 45mm watches we track and the Watch GT 5 than 97% of the 46mm ones — so both wear flatter than their widths suggest.
The Watch GT 5 is 0.8mm wider, 3.1mm shorter, 1.9mm thinner and 9g lighter than the Watch 2 (2018). Both are circular.
