Replacement bands and straps for every Apple Watch, from the Series 1 through the latest Series 12, plus SE and Ultra. Apple Watch bands fit by case size, not model year: a band made for 42mm also fits 44mm, 45mm and 46mm cases, while 38mm bands fit 40mm and 41mm. The Ultra (49mm) uses the larger-size bands. If you are unsure, check the case size on the back of your watch before ordering.Our range covers nylon sport loops, soft silicone sport bands, woven and braided styles, and metal link and Milanese bracelets, in sizes to suit most wrists. Swapping a band takes seconds and needs no tools. New here? Our guide on how to change a watch band walks through it step by step.
