Garmin Descent Mk2S Part 010-02403-00

Which one fits you

Under 18.5 cm (7.3 in) round, the 52mm's lugs overhang and the 43mm's do not; the 43mm fills the wrist at 16–18 cm, the 52mm at 19.5 cm and up.

What else differs

Screen: the 52mm has the larger screen, 1.4 in across against 1.2 in on the 43mm.
Battery: 16 days for the 52mm against 7 days for the 43mm in everyday use; 2 days for the 52mm against 18 hours for the 43mm with GPS on.

3.7mm thinner, the Descent Mk2S is the one that slides under a shirt cuff.

Among the 49 smartwatches 43mm across that we hold thickness for, the Descent Mk2S is thicker than 94%, so it sits higher on the wrist than most of its size.

The Descent Mk2 is 9mm wider, 3.7mm thicker and 43.8g heavier than the Descent Mk2S.
