Using this case is easy. Just carefully place your 45mm Apple Watch Series 7, 8, or 9 into the case. When wearing the watch with the included bracelet band, make sure it fits comfortably on your wrist. For maintenance, use a soft cloth to gently wipe the case and band regularly to keep them looking shiny. Avoid exposing the case to harsh chemicals or extreme temperatures, as this could damage the gold plating or the diamonds. If you notice any loose diamonds or other issues, contact our customer service right away.
