Watch Bands for Seiko Watches

Most Seiko watches take a 20mm band (115 of the 212 models we track) or a 22mm band (66 models). A smaller group uses 18mm (31). The fastest way to be sure is to look up your model number above or measure the gap between your watch’s lugs.

Seiko Seiko 5 watches range from 18mm to 22mm. Of the 66 models we track, 32 use 20mm, 21 use 18mm and 13 use 22mm, so check your exact model.

Seiko 5 Sports watches range from 18mm to 22mm. Of the 39 models we track, 27 use 22mm, 9 use 20mm and 3 use 18mm, so check your exact model.

Curved-end bands fit round cases. 2 Seiko models we track have rectangular, square, octagonal, tonneau or other non-round cases and need a straight-end band: SRPF77 (22mm), SNKP27 (22mm). They are marked “Straight-end only” in the full model list.

Our fit data is matched by lug width: the inside gap between the two lugs, where the band attaches. Measure that gap in millimetres. Most Seiko watches measure 20mm or 22mm. If you land between sizes, choose the even number. For step-by-step help, see our size guide.
