The Rolex Sea-Dweller reference 126600 (commonly known as the SD43) features a black Cerachrom (ceramic) bezel, not a red one. The word "Red" associated with this specific model refers to the iconic single line of red "Sea-Dweller" text printed on the intense black dial, which serves as a 50th-anniversary tribute to the original 1967 vintage model.
