Which one fits you
On wrists narrower than about 59mm, the ColorFit Pro 4 GPS is the safer pick — it stays proportionate down to roughly 47mm, where the Scout Kids starts to hang over the edge. Above 59mm both sit cleanly, and the Scout Kids gives you more presence.
The Scout Kids wears larger than the ColorFit Pro 4 GPS (41.7mm vs 37mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The ColorFit Pro 4 GPS is the slimmer of the two (12mm vs 12.8mm), so it slides under a cuff more easily.
On the wrist the ColorFit Pro 4 GPS feels lighter (41.7g vs 45g, case only).
Among the 49 37mm watches we hold thickness for, the ColorFit Pro 4 GPS is thicker than 65% — it will sit high even though the case width reads modest.
The Scout Kids is middle-of-the-pack for thickness among the 642 42mm watches in the database.
The Scout Kids is 4.7mm wider, 10.7mm longer, 0.8mm thicker and 3.3g heavier than the ColorFit Pro 4 GPS. 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.

Balanced Fit
45mm 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 45mm, 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.

Lugs Overhang
55.7mm on a 55mm wrist
The lugs run 0.4mm past each edge of your wrist — this is a size too big.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 55.7mm — look a size down.
Worn about 20mm further up your forearm it would clear — the arm is roughly 55.9mm across there.
