Ti-Ceramitech is a Panerai material: a titanium alloy put through a patented process that turns its surface into a dense layer of ceramic. It matters because it aims to join titanium’s light weight with ceramic’s resilience.
How is Ti-Ceramitech made?
Panerai starts with a titanium alloy. It then puts the alloy through a patented process. The company says this treatment changes the surface of the metal into ceramic, and that the layer it forms is dense. In plain terms, the process turns titanium into ceramic. The ceramic layer is formed from the alloy itself, rather than added on top of it. Development of the material is reported to have taken seven years.
Why use Ti-Ceramitech for a watch case?
Two figures explain the appeal. First, Ti-Ceramitech weighs 44% less than steel. Second, it has ten times the fracture toughness of ordinary ceramic. Fracture toughness describes how well a material resists cracking. Put simply, the material is meant to be both light and hard to break. On the watches that introduced it, the material is designed to resist high pressure and heat stress while keeping the case light.
Where it comes from
Ti-Ceramitech first appeared on the Submersible QuarantaQuattro Luna Rossa Ti-Ceramitech, in references PAM01466 and PAM01543. On these watches both the 44 mm case and the bezel are made of the material. Ti-Ceramitech is described as inspired by Luna Rossa, and both names sit side by side in the model name. It is also described as a patented titanium ceramic.
