Which one fits you
Both need much the same wrist — roughly 45–61mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Garmin Approach® S50 wears larger than the Samsung Galaxy Watch8 - LTE · 40mm (43mm vs 40.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch8 - LTE · 40mm is the slimmer of the two (8.6mm vs 11.4mm), so it slides under a cuff more easily.
Among the 312 43mm watches we hold thickness for, the Garmin Approach® S50 is thinner than 87%, so it wears flatter than its width suggests.
Among the 509 40mm watches we hold thickness for, the Samsung Galaxy Watch8 - LTE · 40mm is thinner than 83%, so it wears flatter than its width suggests.

2D Dimension Schematics
Every case drawn to scale on a shared centre — from above, and in profile against the wrist. Built from the measurements, so it works for every watch whether or not it has a photo.

- Samsung Galaxy Watch8 - LTE · 40mm40.4mm × 42.7mm · 8.6mm thick
Garmin Approach® S50 vs Samsung Galaxy Watch8 - LTE · 40mm on a wrist
Put Garmin Approach® S50 and Samsung Galaxy Watch8 - LTE · 40mm on the same arm, sized to your own wrist, and turn it. Side by side or stacked on one spot, whichever answers the question faster.
- Garmin Approach® S50 — 43mm case, standing 11.4mm off the wrist.
- Samsung Galaxy Watch8 - LTE · 40mm — 40.4mm case, 42.7mm lug-to-lug, standing 8.6mm off the wrist.
Whether that clears your wrist edges is the question worth answering, and it depends on your wrist rather than on the case diameter.
See them on a wrist in 3DCase shapes are generated from each watch's published measurements — case width, lug-to-lug and thickness — not from manufacturer 3D models, so the proportions are accurate while the dial is generic.
Battery life compared
