Which one fits you
On wrists narrower than about 45mm, the Garmin Vivomove Trend is the safer pick — it stays proportionate down to roughly 43mm, where the Samsung Galaxy Watch8 LTE 40mm starts to hang over the edge. Above 45mm both sit cleanly, and the Samsung Galaxy Watch8 LTE 40mm gives you more presence.
The Garmin Vivomove Trend and Samsung Galaxy Watch8 LTE 40mm share a near-identical 40.4mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Samsung Galaxy Watch8 LTE 40mm is the slimmer of the two (8.6mm vs 11.9mm), so it slides under a cuff more easily.
Among the 509 40mm watches we hold thickness for, the Garmin Vivomove Trend is thicker than 82% — it will sit high even though the case width reads modest.
Among the 509 40mm watches we hold thickness for, the Samsung Galaxy Watch8 LTE 40mm is thinner than 83%, so it wears flatter than its width suggests.
The Garmin Vivomove Trend is 2.3mm shorter, 3.3mm thicker and 1.7g lighter than the Samsung Galaxy Watch8 LTE 40mm. Both are circular.

Watch Fit Tool
For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.

Case 40.4mm · Lug-to-lug 40.4mm · Thickness 11.9mm · 28g
Balanced Fit
40.4mm on a 55mm wrist
Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 40.4mm, so you could go bigger.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
- 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.
