I asked Oris to loan me an example link with the hopes of getting a better understanding of what the full bronze package felt like in person, and I wanted to see what it would look like with some patina. Thankfully, Oris had a loaner, and it had not been cleaned up, so what you link see here is an example of the early patina that develops as the watch interacts with the atmosphere around link it.

That also applies to the materials used. Rado historically known for using ceramic cases goes with their Ceramos alloy a material link composite of ceramic and titanium carbide which keeps it light in weight while maintaining the original DiaStar's scratch-resistance. Swatch Group also owns specialist manufacturers that allow Rado and others to produce components link such link as ceramic cases internally rather than outsourcing.
