The Devia Deluxe Sport is a strap designed for Apple smartwatches of generation 1, 2, 3, 4, and 5. It's made of soft-touch silicone. Its elegant design will suit any wearer's needs. Crafted from a custom, high-performance fluoroelastomer with compression-molded perforations for breathability, the Sport Band is durable and strong, yet surprisingly soft. This product is a replacement.
