Amazfit Watches Under 40mm

25 Amazfit models in the 0–40mm range, actually measuring 11mm to 38.7mm. Compact sizing that suits smaller wrists and dressier looks.

Thickness is where they separate: 8.8mm to 13.7mm. That 4.9mm gap decides whether a watch slides under a shirt sleeve.

3 are round and 22 rectangular — at the same nominal width, a rectangular case covers noticeably more wrist.

Releases run from 2019 to 2023, so this mixes current models with older references.
