Using this watch band is super easy. First, if you want to switch it out, just press down on the easy - release mechanism. Then, align the new band with the pinholes on both sides of your watch. When it comes to compatibility, it fits Apple Watch Series 1 - 9, Apple Watch Ultra, and Samsung Galaxy Watches with 20mm straps. Remember, because of the unique nature of the material, the exact colors and patterns might be a bit different from what you see in the picture. To keep your watch band in good shape, clean it gently with a soft cloth. Avoid exposing it to harsh chemicals or excessive moisture, as this could damage the band.
