Watch Fit Tool

For sports watches, Lug-to-Lug (L2L) is what matters most. Bulky is fine — overhang is not.

Which one fits you

On wrists narrower than about 48mm, the Garmin Approach® S50 is the safer pick — it stays proportionate down to roughly 45mm, where the Amazfit Pop 3R starts to hang over the edge. Above 48mm both sit cleanly, and the Amazfit Pop 3R gives you more presence.

The Amazfit Pop 3R 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 Amazfit Pop 3R is the slimmer of the two (10.8mm vs 11.4mm), so it slides under a cuff more easily.

On the wrist the Garmin Approach® S50 feels lighter (29g vs 55.48g, case only).

Among the 461 46mm watches we hold thickness for, the Amazfit Pop 3R is thinner than 97%, so it wears flatter than its width suggests.

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.
