Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 49mm, the Garmin Bounce 2 is the safer pick — it stays proportionate down to roughly 45mm, where the Noise HRX Bounce starts to hang over the edge. Above 49mm both sit cleanly, and the Noise HRX Bounce gives you more presence.
The Noise HRX Bounce wears larger than the Garmin Bounce 2 (46.7mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Noise HRX Bounce is the slimmer of the two (11mm vs 12.4mm), so it slides under a cuff more easily.
On the wrist the Garmin Bounce 2 feels lighter (26.5g vs 35g, case only).
The Garmin Bounce 2 is thinner than 75% of the 43mm watches we track and the Noise HRX Bounce than 87% of the 47mm ones — so both wear flatter than their widths suggest.
The Noise HRX Bounce is 3.7mm wider, 3.7mm longer, 1.4mm thinner and 8.5g heavier than the Garmin Bounce 2. 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 43.0mm · Lug-to-lug 43.0mm · Thickness 12.4mm · 27g
Balanced Fit
43mm 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 43mm, 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.
