Which one fits you

On wrists narrower than about 49mm, the Forerunner® 165 is the safer pick — it stays proportionate down to roughly 45mm, where the Forerunner® 970 starts to hang over the edge. Above 49mm both sit cleanly, and the Forerunner® 970 gives you more presence.

The Forerunner® 970 wears larger than the Forerunner® 165 (47mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Forerunner® 165 is the slimmer of the two (11.6mm vs 12.9mm), so it slides under a cuff more easily.

On the wrist the Forerunner® 165 feels lighter (39g vs 56g, case only).

Among the 318 43mm watches we hold thickness for, the Forerunner® 165 is thinner than 86%, so it wears flatter than its width suggests.

The Forerunner® 970 is middle-of-the-pack for thickness among the 102 47mm watches in the database.

The Forerunner® 970 is 4mm wider, 4mm longer, 1.3mm thicker and 17g heavier than the Forerunner® 165. 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

43mm on a 55mm wrist

10:09TUE 12lug to lug 43.0mmyour 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 4753mm lug to lug. This one is 43mm, 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.
