Girard Perregaux

You do realise that ceramic is essentially scratchproof?

 

Its hardness is 8 on the Mohs scale, with sapphire/cardorundum above it, at 9, and diamond topping the scale at 10. There’s not an awful lot to worry about, apart from the material being brittle – which is only a concern if you’re clumsy and drop it on a hard surface!
Treat it accordingly, and you’ll have a watch that will still look brand new for as long as you own it.
