Which one fits you
On wrists narrower than about 53mm, the MARQ® Athlete (Gen 2) - Carbon Edition is the safer pick — it stays proportionate down to roughly 48mm, where the Instinct® 3 – 50 mm, Solar starts to hang over the edge. Above 53mm both sit cleanly, and the Instinct® 3 – 50 mm, Solar gives you more presence.
The Instinct® 3 – 50 mm, Solar wears larger than the MARQ® Athlete (Gen 2) - Carbon Edition (50mm vs 46mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Instinct® 3 – 50 mm, Solar is the slimmer of the two (14.4mm vs 15mm), so it slides under a cuff more easily.
On the wrist the Instinct® 3 – 50 mm, Solar feels lighter (58g vs 75g, case only).
Among the 211 46mm watches we hold thickness for, the MARQ® Athlete (Gen 2) - Carbon Edition is thicker than 70% — it will sit high even though the case width reads modest.
The Instinct® 3 – 50 mm, Solar is 4mm wider, 4mm longer, 0.6mm thinner and 17g lighter than the MARQ® Athlete (Gen 2) - Carbon Edition. 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.

Sweet Spot
50mm on a 55mm wrist
Across the wrist it works — 2.5mm spare each side — but a tall watch on this wrist. Fine over a sleeve, awkward under one.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 50mm.
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.

- Across the wrist2.5mm spare each side

- Off the wrist14.4mm off the skin
A tall watch on this wrist. Fine over a sleeve, awkward under one. (14.4mm case, back against the skin)
- How it seats~8.0mm under the rim

Substantial without being a burden — the usual weight of a steel watch on a wrist this size. (1.1g per mm of wrist)

Balanced Fit
46mm on a 55mm wrist
Across the wrist it works — 4.5mm spare each side — but a tall watch on this wrist. Fine over a sleeve, awkward under one.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 46mm, 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.
