Sterile Cali dial. Miyota auto movement. 4.5mm thick anti reflactive sapphire. Comes with pelican box and 2 extra rubber straps. Will also come with original carbon fiber dial. 46mm w/o crown, 22mm lugs. Awsome looking watch and there are no other ones like it. Case is the same as Nitrox. $150 shipped CONUS. Paypal only.
