Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 51mm, the Honor Band Z1 is the safer pick — it stays proportionate down to roughly 40mm, where the Watch D2 starts to hang over the edge. Above 51mm both sit cleanly, and the Watch D2 gives you more presence.
The Honor Band Z1 and Watch D2 share a near-identical 38mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Honor Band Z1 is the slimmer of the two (9.5mm vs 13.3mm), so it slides under a cuff more easily.
On the wrist the Honor Band Z1 feels lighter (25g vs 40g, case only).
Among the 356 38mm watches we hold thickness for, the Honor Band Z1 is thinner than 78%, so it wears flatter than its width suggests.
Among the 356 38mm watches we hold thickness for, the Watch D2 is thicker than 90% — it will sit high even though the case width reads modest.
The Honor Band Z1 is 10mm shorter, 3.8mm thinner and 15g lighter than the Watch D2.
