Which one fits you
On wrists narrower than about 55mm, the Watch Fit 4 Pro is the safer pick — it stays proportionate down to roughly 47mm, where the Watch Kids 5X starts to hang over the edge. Above 55mm both sit cleanly, and the Watch Kids 5X gives you more presence.
The Watch Kids 5X wears larger than the Watch Fit 4 Pro (41mm vs 40mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Watch Fit 4 Pro is the slimmer of the two (9.3mm vs 14.55mm), so it slides under a cuff more easily.
On the wrist the Watch Fit 4 Pro feels lighter (30.4g vs 57.5g, case only).
Among the 540 40mm watches we hold thickness for, the Watch Fit 4 Pro is thinner than 77%, so it wears flatter than its width suggests.
Among the 374 41mm watches we hold thickness for, the Watch Kids 5X is thicker than 91% — it will sit high even though the case width reads modest.
The Watch Kids 5X is 1mm wider, 7.5mm longer, 5.3mm thicker and 27.1g heavier than the Watch Fit 4 Pro. Both are rectangle.
