Gun metal coloured These really got overlooked for potential I only wish I’d brought the lot of them now ! They are stunning the beads are small at a guess I’d say 1/2mm ball bearing size and teal metallic coloured .they pivot/ are hinged too for shirt button hole access Get them while you can I only wish I had more The finish on body is antiquegrey industrial colour hard to sum up but absolutely corking There are other watch companies now offering a copy of the nautilus look with the Tiffany colour scheme I know the original is in the millions and hard to come by
