Samsung Watches Under 40mm

12 Samsung models in the 0–40mm range, actually measuring 36.9mm to 39.9mm. Compact sizing that suits smaller wrists and dressier looks.

Thickness is where they separate: 8.9mm to 12.5mm. That 3.6mm gap decides whether a watch slides under a shirt sleeve.

7 are round and 5 rectangular — at the same nominal width, a rectangular case covers noticeably more wrist.

Releases run from 2015 to 2024, so this mixes current models with older references.

Same size, other brands

The middle of this group sits around 39mm. These are the closest matches we hold from other brands — useful when the size is right but the Samsung isn't.
