Apple Watch Ultra-Light Integrated Solo Loop Silicone Band Belt series 7 6 5 4 3 2 1 SE Replacement Band (38/40mm S) E429 ■ This ultra-lightweight, integrated silicone band is made of comfortable liquid silicone and is designed specifically for Apple Watch, with no buckle. ■ Softer and more flexible than the Sport Band, it fits snugly on your wrist. ■ While it takes a little effort to put on because the band is sized to fit your wrist, the absence of a clasp makes it comfortable and gives a very smart impression. ■ The biggest advantage of not having metal parts is that the clasp won't rub against your palm rest when you're working on a computer. Just the absence of that rubbing makes PC work more comfortable. ■ You can wear it for long periods during sports and outdoor activities, with a non-slip and smooth fit. Compatible with Apple Watch Series Ultra/SE/8/7/6/5/4/3/2/1
