A landmark creation of Gérald Genta and a cornerstone of modern horology, the Audemars Piguet Royal Oak reference 5402 remains one of the most iconic and influential wristwatch designs ever conceived. The present example reference 5402SA in steel and yellow gold represents a particularly compelling and rare configuration of this early generation “Jumbo”, produced in small quantities and now increasingly admired by connoisseurs for its bold yet understated two-tone presence.

The light grey “Petite Tapisserie” dial, beautifully preserved and free from notable blemishes, displays the highly coveted “AP” applied logo at 6 o’clock, an identifying trait of the earliest and most desirable executions. The applied yellow-gold hour markers and hands provide a warm contrast against the architectural dial texture, enhancing the depth and elegance for which the Royal Oak has become celebrated.

Case and bracelet remain in strong and attractive condition, exhibiting the sharp geometry and play of satin and polished surfaces that define the model’s iconic personality. The proportions of the original 39 mm Jumbo case, remarkably slim yet visually powerful, reinforce the reference’s pioneering role as the first luxury sport watch in history.

This example is individually numbered No. 331, denoting an early production within the 5402SA lineage, a detail further enhancing its collectability. Powered by the ultra-thin automatic calibre 2121, derived from the legendary Jaeger-LeCoultre 920, the movement remains a mechanical achievement still revered for its finesse and reliability.

Seldom encountered, especially in such coherent and well-preserved form, the 5402SA embodies the pure essence of Genta’s original design while offering a distinctive two-tone interpretation that feels both audacious and timeless. A rare opportunity to acquire a historically significant Royal Oak that captures the pioneering spirit and enduring allure of the world’s first luxury sports watch.
