The blue reference is listed with a 21 mm lug width and a quick-release bracelet. Tissot also presents 21 mm quick-release fabric straps as compatible options. Before ordering another strap, verify both its 21 mm width and that its attachment fits the watch’s quick-release connection; width alone does not confirm connector compatibility.
