In reply to Mark Austin.

As far as we know, the only brown Cerachrom ceramic bezels are the all-brown tachymeter bezel on the Platinum Daytona, and the half-black/half-brown one on the current two-tone and solid Everose gold GMT. In regards to solid-color Cerachrom bezels for the GMT-Master II series, the only one that Rolex has offered is the all-black one that initially was fitted to updated generation of GMT-Master watches.
