Is the Garmin Approach® S20 thick for a 37mm watch?

Zenith Defy A3643 Revival, Omega Museum Collection Seamaster Milano Cortina 2026 Winter Olympics, Kieslect Ks2, Noise ColorFit Icon 3 all sit within half a millimetre of the Garmin Approach® S20's 37.4mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Garmin Approach® S20?
