The one closest to the original is the "Jumbo" stainless steel case style 16202ST, adhering to the design features of the original Royal Oak series in 1972. The stainless steel case and strap are hand satin-finished and polished and chamfered. Cloud Night Blue 50" shade and "Petite Tapisserie" small check surface. The special blue is produced by electroplating, and the "cloud" in the hue name describes the cloudy rendering effect that occurs when the black pigment comes into contact with the protective paint.
