Garmin
Approach® S50 (010-03010-00)
Garmin
Descent™ Mk3i – 51 mm (010-02752-10)
The Garmin Descent™ Mk3i – 51 mm wears larger than the Garmin Approach® S50 (51mm 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 16.4mm), so it slides under a cuff more easily.
On the wrist the Garmin Approach® S50 feels lighter (29g vs 77.8g, case only).
