I don’t usually post boutique models but this Chanel looks OK for maybe an effete world-traveller with a watch scratching phobia.
The new Chanel J12 GMT with a black ceramic case has a nice 42 mm wide and 10 mm thick. Chanel claims that is unscratchable and stain-resistant. I have never had a problem with stains on any watch, but scratches are a different story. I do find it hard to believe that they made this ceramic material unscratchable and I would definitely have to see it to believe it.
Actually, Rado has done something like this too, with ceramic case:
