TAG Heuer Watches Under 40mm

581 TAG Heuer models in the 0–40mm range, actually measuring 27mm to 39.2mm. Compact sizing that suits smaller wrists and dressier looks.

Thickness is where they separate: 9.1mm to 16.2mm. That 7.1mm gap decides whether a watch slides under a shirt sleeve.

464 are round and 104 rectangular — at the same nominal width, a rectangular case covers noticeably more wrist.

Releases run from 2000 to 2026, so this mixes current models with older references.
