Crystal Skeleton Caseback is a type of watch case which is designed to show off the intricate movements of the watch’s inner workings. The crystal caseback is made of a transparent, scratch-resistant material, usually sapphire crystal, which allows the wearer to view the watch’s inner workings. The caseback has a skeletonized design, which allows more of the inner workings to be seen. The combination of the crystal and the skeleton design creates a unique and eye-catching look.
