Born in 1972, the Royal Oak was truly a revolutionary movement into an new ear of luxury sports watch. Debuted with the first ever Royal Oak reference 5402 in a stainless steel cased at 39mm, also known as the “Jumbo”, the famous Gerald Genta design mastered the ratio perfectly thanks to the ultra-slim movement caliber 2121, the rest is history. With the success and demand of this ground-breaking design, it did not take long for the Royal Oak to expand its offerings for its growing clientele. During the mid 1970s, Audemars Piguet introduced the 5402BA in solid gold and 5402SA with a two-tone stainless steel and yellow gold appearance, the present example is one of such. A fantastic combination with the robustness of steel and the richness of the yellow metal, the ref. 5402SA features a matching gold date wheel that perfectly complements the warm grey dial. According to scholars, approximately 951 examples of the two-tone reference were made, the present example is numbered 584 on its caseback.

With a celebration of the 50th anniversary of the Royal Oak this very year, the present two-tone ref. 5402SA with incredible vintage aesthetics synonymous to the period is a perfect daily watch for the discerned collector.
