Which one fits you
On wrists narrower than about 51mm, the Garmin Venu 4 - 45mm is the safer pick — it stays proportionate down to roughly 47mm, where the Huawei Watch Ultimate starts to hang over the edge. Above 51mm both sit cleanly, and the Huawei Watch Ultimate gives you more presence.
The Huawei Watch Ultimate wears larger than the Garmin Venu 4 - 45mm (48.5mm vs 45mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Garmin Venu 4 - 45mm is the slimmer of the two (12mm vs 13mm), so it slides under a cuff more easily.
On the wrist the Garmin Venu 4 - 45mm feels lighter (38g vs 76g, case only).
The Garmin Venu 4 - 45mm is thinner than 76% of the 45mm watches we track and the Huawei Watch Ultimate than 73% of the 49mm ones — so both wear flatter than their widths suggest.
The Huawei Watch Ultimate is 3.5mm wider, 3.5mm longer, 1mm thicker and 38g heavier than the Garmin Venu 4 - 45mm. Both are circular.
