Besides experimenting with gold, Panerai also introduced an all-black GMT matte ceramic watch with the PAM 438 that's been christened Tuttonero. It's the first time they've used ceramic to construct a bracelet and the blackout-look extends all the way to the movement which also has a power reserve indication, visible via the sapphire see-through caseback. The ceramic used is a synthetic material that's five times harder than stainless steel and is scratch-resistant. There is also a strap version which is PAM 441.
