Sapphire crystal glass front and back ensures the movement is perfectly protected from scratches.the tourbo x features a see through case back and contemporary 3d roman numeral dial with semi transparent back, allowing you to see the movement underneath in more detail. This limited edition piece is available in solid stainless steel with exhibition case back. Water resistant to 50m.
