Which one fits you

On wrists narrower than about 54mm, the Forerunner® 165 is the safer pick — it stays proportionate down to roughly 45mm, where the Enduro 3 starts to hang over the edge. Above 54mm both sit cleanly, and the Enduro 3 gives you more presence.

The Enduro 3 wears larger than the Forerunner® 165 (51mm 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 15.7mm), so it slides under a cuff more easily.

On the wrist the Forerunner® 165 feels lighter (39g vs 63g, case only).

Among the 43 51mm watches we hold thickness for, the Enduro 3 is thicker than 74% — it will sit high even though the case width reads modest.

Among the 312 43mm watches we hold thickness for, the Forerunner® 165 is thinner than 86%, so it wears flatter than its width suggests.

The Enduro 3 is 8mm wider, 8mm longer, 4.1mm thicker and 24g heavier than the Forerunner® 165. Both are circular.

For sports watches, Lug-to-Lug (L2L) is what matters most. Bulky is fine — overhang is not.
