Seiko Watches 40–44mm

68 Seiko models in the 40–44mm range, actually measuring 40mm to 43.8mm. The most versatile mid-size range for average wrists.

Thickness barely moves across the group — 13mm to 14.5mm — so these wear much alike under a cuff.

67 are round and 1 rectangular — at the same nominal width, a rectangular case covers noticeably more wrist.

Releases run from 2010 to 2022, so this mixes current models with older references.
