Case: 42.4mmL2L: 42.4mmThick: 12.9mm
Balanced Fit6.3mm clearance. Comfortable everyday wear with room to spare.

The Garmin Forerunner® 245 Music and Garmin Forerunner® 570 - 42mm share a near-identical 42.3mm case, so wrist presence comes down to thickness, lug-to-lug and weight.

The Garmin Forerunner® 245 Music is the slimmer of the two (12.2mm vs 12.9mm), so it slides under a cuff more easily.

On the wrist the Garmin Forerunner® 245 Music feels lighter (38.5g vs 42g, case only).
