Which one fits you

On wrists narrower than about 47mm, the Garmin Forerunner® 165 Music is the safer pick — it stays proportionate down to roughly 45mm, where the Google Pixel Watch 4 - 45mm starts to hang over the edge. Above 47mm both sit cleanly, and the Google Pixel Watch 4 - 45mm gives you more presence.

The Google Pixel Watch 4 - 45mm wears larger than the Garmin Forerunner® 165 Music (45mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin Forerunner® 165 Music is the slimmer of the two (11.6mm vs 12.3mm), so it slides under a cuff more easily.

On the wrist the Google Pixel Watch 4 - 45mm feels lighter (36.7g vs 39g, case only).

The Garmin Forerunner® 165 Music is thinner than 86% of the 43mm watches we track and the Google Pixel Watch 4 - 45mm than 70% of the 45mm ones — so both wear flatter than their widths suggest.

The Google Pixel Watch 4 - 45mm is 2mm wider, 2mm longer, 0.7mm thicker and 2.3g lighter than the Garmin Forerunner® 165 Music. Both are circular.

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