Does the Forerunner® 15 fit your wrist?

Drag the slider to your wrist width and see the Forerunner® 15 overlaid at true scale. Lug-to-lug — not case diameter — decides whether a watch overhangs your wrist.

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