Which one fits you
Both need much the same wrist — roughly 48–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Watch 5 Pro Bluetooth and Watch GS 3i share a near-identical 46.3mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Watch GS 3i is the slimmer of the two (10.7mm vs 11.3mm), so it slides under a cuff more easily.
On the wrist the Watch GS 3i feels lighter (44g vs 51g, case only).
The Watch 5 Pro Bluetooth is thinner than 72% of the 162 46mm watches we hold thickness for, the Watch GS 3i than 97% — so both wear flatter than their widths suggest.
The Watch 5 Pro Bluetooth is 0.4mm wider, 0.4mm longer, 0.6mm thicker and 7g heavier than the Watch GS 3i. 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 46.3mm · Lug-to-lug 46.3mm · Thickness 11.3mm · 51g
Balanced Fit
46.3mm 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 46.3mm, 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.
