The Royal Oak shook the world of watchmaking and changed it forever: the first steel luxury watch. Designed by Gerald Genta, it was the first in a lot of things, including in sport watches with an integrated bracelet. The reference 56175ST captures all the essence of the first Royal Oak, in a compact size of 33 millimeters, which is also extremely comfortable thanks to its quartz caliber, which only requires you to put it on your wrist to start enjoying it.
