Which one fits you

On wrists narrower than about 53mm, the Forerunner 570 42mm is the safer pick — it stays proportionate down to roughly 45mm, where the Instinct 2X Solar starts to hang over the edge. Above 53mm both sit cleanly, and the Instinct 2X Solar gives you more presence.

The Instinct 2X Solar wears larger than the Forerunner 570 42mm (50mm vs 42.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Forerunner 570 42mm is the slimmer of the two (12.9mm vs 14.5mm), so it slides under a cuff more easily.

On the wrist the Forerunner 570 42mm feels lighter (42g vs 67g, case only).

The Forerunner 570 42mm is middle-of-the-pack for thickness among the 720 42mm watches in the database.

The Instinct 2X Solar is 7.6mm wider, 7.6mm longer, 1.6mm thicker and 25g heavier than the Forerunner 570 42mm. 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.

Balanced Fit

42.4mm on a 55mm wrist

10:09TUE 12lug to lug 42.4mmyour wrist 55.0mm

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 42.4mm, so you could go bigger.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 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. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.

Sweet Spot

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.
