Using this butterfly buckle leather strap for your Apple Watch is a breeze. First, open the butterfly buckle gently and slide the strap onto your watch. Adjust it to fit your wrist comfortably, then close the buckle securely. When it comes to maintenance, keep your strap away from sharp objects to avoid scratches. If it gets dirty, you can use a soft, damp cloth to wipe it clean. Avoid exposing it to extreme heat or moisture as this may damage the leather. Remember, although it's new without tags, it's ready to give your Apple Watch a fresh and stylish look right out of the box.
