Which one fits you
On wrists narrower than about 50mm, the Watch GT is the safer pick — it stays proportionate down to roughly 48mm, where the Watch GT 2 Bluetooth starts to hang over the edge. Above 50mm both sit cleanly, and the Watch GT 2 Bluetooth gives you more presence.
The Watch GT 2 Bluetooth wears larger than the Watch GT (40.2mm vs 39.6mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Watch GT feels lighter (33g vs 35.8g, case only).
The Watch GT is middle-of-the-pack for thickness among the 561 40mm watches in the database.
Among the 530 40mm watches we hold thickness for, the Watch GT 2 Bluetooth is thicker than 65% — it will sit high even though the case width reads modest.
The Watch GT 2 Bluetooth is 0.6mm wider, 1.7mm longer, 0.2mm thinner and 2.8g heavier than the Watch GT. Both are rectangle.

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 45.8mm · Lug-to-lug 45.8mm · Thickness 11.2mm · 33g
Balanced Fit
45.8mm 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 45.8mm, 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.

Sweet Spot
47.5mm on a 55mm wrist
Across the wrist it works — 3.8mm spare each side — but wide enough that the edge of the case back lifts clear of the skin.
