The Royal Oak was a groundbreaking model both for the Audemars Piguet brand and the watch industry as whole. The model’s strikingly unconventional design, with a hexagonal bezel, exposed screws, and integrated bracelet, turned the world of luxury watch design upside down. Although its unique, bold, and unusual design was polarizing at first, the Royal Oak was ultimately a hit. In fact, the Royal Oak has become Audemars Piguet’s flagship model.
