The 5402ST is the original Royal Oak — designed by Gerald Genta in a single night, launched at Baselworld 1972 at a price higher than gold dress watches. The "Jumbo" (39mm) octagonal bezel with eight exposed screws and integrated bracelet redefined what a luxury sport watch could be. Production ran in three numbered series (A, B, C) through 1980.
