Bounce 2
Garmin
Descent™ Mk2S (010-02403-00)
The Garmin Bounce 2 and Garmin Descent™ Mk2S share a near-identical 43mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Garmin Bounce 2 is the slimmer of the two (12.4mm vs 14.15mm), so it slides under a cuff more easily.
On the wrist the Garmin Bounce 2 feels lighter (26.5g vs 60g, case only).
