Garmin Descent™ G2 (010-02986-00)
Case: 45.5mmL2L: 45.5mmThick: 15.2mm
Balanced Fit4.75mm clearance. Comfortable everyday wear with room to spare.

The Garmin Descent™ G2 wears larger than the Garmin Approach® S50 (45.5mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin Approach® S50 is the slimmer of the two (11.4mm vs 15.2mm), so it slides under a cuff more easily.

On the wrist the Garmin Approach® S50 feels lighter (29g vs 65g, case only).
