Which one fits you
On wrists narrower than about 50mm, the Galaxy Watch7 - LTE · 44mm is the safer pick — it stays proportionate down to roughly 47mm, where the Galaxy Watch Ultra starts to hang over the edge. Above 50mm both sit cleanly, and the Galaxy Watch Ultra gives you more presence.
The Galaxy Watch Ultra wears larger than the Galaxy Watch7 - LTE · 44mm (47.4mm vs 44.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Galaxy Watch7 - LTE · 44mm is the slimmer of the two (9.7mm vs 12.1mm), so it slides under a cuff more easily.
On the wrist the Galaxy Watch7 - LTE · 44mm feels lighter (33.8g vs 60.5g, case only).
The Galaxy Watch Ultra is thinner than 86% of the 47mm watches we track and the Galaxy Watch7 - LTE · 44mm than 100% of the 44mm ones — so both wear flatter than their widths suggest.
The Galaxy Watch Ultra is 3mm wider, 3mm longer, 2.4mm thicker and 26.7g heavier than the Galaxy Watch7 - LTE · 44mm. Both are circular.
