Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 49mm, the Forerunner® 165 Music is the safer pick — it stays proportionate down to roughly 45mm, where the Forerunner® 265 starts to hang over the edge. Above 49mm both sit cleanly, and the Forerunner® 265 gives you more presence.
The Forerunner® 265 wears larger than the Forerunner® 165 Music (46.1mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Forerunner® 165 Music 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 Music feels lighter (39g vs 47g, case only).
Among the 312 43mm watches we hold thickness for, the Forerunner® 165 Music is thinner than 86%, so it wears flatter than its width suggests.
The Forerunner® 265 is middle-of-the-pack for thickness among the 150 46mm watches in the database.
The Forerunner® 265 is 3.1mm wider, 3.1mm longer, 1.3mm thicker and 8g heavier than the Forerunner® 165 Music. Both are circular.
