      The alloy derived from copper and zinc is brass.  It does not CLEAN itself, but the following website tells you how to clean brass:

      As to self-disinfection, I quote:  Many infections can be spread by doorknobs. Brass doorknobs disinfect themselves in about eight hours, while stainless steel and aluminium knobs never do.

            I wasn't familiar with link the Wadden Sea link prior to learning of this Oris collaboration, and I suspect many readers in the United States link are in the same boat. So what the story behind Oris producing a watch in its honor?
