Using this watch bracelet is easy. Just attach it to your Apple Watch® that's in the 42mm to 49mm size range. Open the two - presser clasp and slide the bracelet onto the watch. Close the clasp firmly to ensure it stays in place. As for maintenance, keep it away from sharp objects to avoid scratching the ceramic and stainless - steel parts. You can clean it with a soft, dry cloth. Don't expose it to extreme heat or chemicals, as these may damage the materials. And remember, the watch face isn't included, so you'll need to buy that separately.
