The Royal Oak “Jumbo” Extra-Thin is the ultimate tribute to the original 1972 Royal Oak designed by Gérald Genta. Combining a contemporary aesthetic with technical mastery, this reference remains faithful to the proportions and spirit of the timepiece that revolutionized the luxury watch world. Its remarkably thin profile and iconic silhouette make it a cornerstone of the House’s heritage.
