The rose gold has a very warm tone and looks like bronze.
The alloy seems to be extremely hard.
I haven't found the slightest scratch on the case yet. Not even the finest scratches from shirt sleeves etc.
I once hit a rough wall with the clasp. My heart stopped in shock. I then examined the clasp with a magnifying glass. Not a hint of a scratch. So the watch is really suitable for everyday use. ๐
