US Patent 10463119 Band with magnetic closure mechanism

A band for a wearable device includes a first strap having a magnetic insert defining an array of holes, and a second strap having a magnetic protrusion configured to be at least partially disposed in a respective hole of the array of holes and to magnetically couple to the magnetic insert. A method of manufacturing a magnetic strap for a wearable device includes disposing a magnetizable insert between a first layer and a second layer, and coupling the first layer to the second layer such that the magnetizable insert is retained between the first layer and the second layer. The magnetizable insert includes a magnetizable material suspended in a polymer.
