Watch Bands for Hamilton Watches

Most Hamilton watches take a 20mm band (289 of the 618 models we track) or a 22mm band (255 models). A smaller group uses 18mm (62) or 24mm (12). The fastest way to be sure is to look up your model number above or measure the gap between your watch’s lugs.

Hamilton Jazzmaster watches range from 18mm to 24mm. Of the 231 models we track, 99 use 22mm, 94 use 20mm, 31 use 18mm and 7 use 24mm, so check your exact model.

Hamilton Khaki Field watches range from 18mm to 24mm. Of the 85 models we track, 69 use 20mm, 10 use 22mm, 3 use 18mm and 3 use 24mm, so check your exact model.

Curved-end bands fit round cases. 13 Hamilton models we track have rectangular, square, octagonal, tonneau or other non-round cases and need a straight-end band: H12451155 (18mm), H13431553 (18mm), H13519711 (22mm), H15515851 (22mm), H11411155 (18mm), H11421114 (18mm), H12451855 (18mm), H13421511 (18mm), H13421611 (18mm), H13421811 (18mm), H13519641 (22mm), H32856705 (24mm), H32866781 (24mm). 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 Hamilton watches measure 20mm or 22mm. If you land between sizes, choose the even number. For step-by-step help, see our size guide.
