Size, specs & wrist fit compared

Which one fits you
Both need much the same wrist — roughly 50–69mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Huawei Watch Ultimate wears larger than the Samsung Galaxy Watch Ultra (48.5mm vs 47.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch Ultra is the slimmer of the two (12.1mm vs 13mm), so it slides under a cuff more easily.
On the wrist the Samsung Galaxy Watch Ultra feels lighter (60.5g vs 76g, case only).
The Huawei Watch Ultimate is thinner than 73% of the 49mm watches we track and the Samsung Galaxy Watch Ultra than 86% of the 47mm ones — so both wear flatter than their widths suggest.
The Huawei Watch Ultimate is 1.1mm wider, 1.1mm longer, 0.9mm thicker and 15.5g heavier than the Samsung Galaxy Watch Ultra. Both are circular.
