A disruptive and downright revolutionary timepiece, the Royal Oak is immediately recognizable thanks to its state-of-the-art engineered strongbox case, octagonal bezel secured by eight hexagonal screws, visible water resistance gaskets, dials adorned with exclusive engine-turned “Grande Tapisserie” motif. An immersion into the heart of the calibre 5122 thanks to sculptural openworking that powerfully highlights the octagonal shape of the Royal Oak.
