Which one fits you
On wrists narrower than about 45mm, the Honor Band Z1 is the safer pick — it stays proportionate down to roughly 40mm, where the Watch Fit 4 starts to hang over the edge. Above 45mm both sit cleanly, and the Watch Fit 4 gives you more presence.
The Honor Band Z1 and Watch Fit 4 share a near-identical 38mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Honor Band Z1 feels lighter (25g vs 27g, case only).
The Honor Band Z1 is thinner than 78% of the 356 38mm watches we hold thickness for, the Watch Fit 4 than 78% — so both wear flatter than their widths suggest.
The Honor Band Z1 is 5mm shorter and 2g lighter than the Watch Fit 4.
