Which one fits you
On wrists narrower than about 45mm, the Samsung Galaxy Watch7 - Wi-Fi · 40mm is the safer pick — it stays proportionate down to roughly 43mm, where the Garmin Bounce 2 starts to hang over the edge. Above 45mm both sit cleanly, and the Garmin Bounce 2 gives you more presence.
The Garmin Bounce 2 wears larger than the Samsung Galaxy Watch7 - Wi-Fi · 40mm (43mm vs 40.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch7 - Wi-Fi · 40mm is the slimmer of the two (9.7mm vs 12.4mm), so it slides under a cuff more easily.
On the wrist the Garmin Bounce 2 feels lighter (26.5g vs 33.8g, case only).
Among the 312 43mm watches we hold thickness for, the Garmin Bounce 2 is thinner than 76%, so it wears flatter than its width suggests.
