Certina Watches 40–44mm

379 Certina models in the 40–44mm range, actually measuring 40mm to 43.5mm. The most versatile mid-size range for average wrists.

Thickness is where they separate: 7.8mm to 15.9mm. That 8.2mm gap decides whether a watch slides under a shirt sleeve.

344 are round and 17 rectangular — at the same nominal width, a rectangular case covers noticeably more wrist.

Releases run from 2014 to 2026, so this mixes current models with older references.
