Chanel’s newest watch takes off where their all-black J12 left off two decades ago. But the new timepiece—called the J12 X-Ray—takes a rather different approach: its case is made entirely from sapphire crystal.

All major components in the watch are made from sapphire, as well. The list includes bridges, strap links, and plate. Other features of the watch include baguette-cut diamonds for hour markers. The look is undeniably arresting; the diamonds that serve as markers appear to float above the face of the watch.

Two other watches join the X-Ray in the J12 rebirth. The X-Ray is limited in production to 12 examples, and will be priced at just over $625K.
