The modern interpretation of a design developed in Milan at the end of the 19th century. Woven on special Italian machines, the smooth stainless steel mesh fits perfectly around the wrist. And because it is fully magnetic, the Milanese strap is individually adjustable and fits perfectly. You can combine most straps with any Apple Watch Series 3 case or newer cases of the same size. 41 mm straps fit 38 mm and 40 mm cases. 45 mm straps fit 42 mm, 44 mm, and 49 mm cases.
