The Audemars Piguet Royal Oak reference 5402 was unveiled at the Basel Fair in 1972, marking a revolutionary shift in luxury w🃏atchmaking with its use of stainless steel. Designed by the legendary Gérald Genta, the Royal Oak showcased exceptional engineering. Its monobloc case, characterized by a distinct maritime aesthetic, features an octagonal bezel secured by eight hexagonal white gold screws and a tapisserie motif dial. Lean, sporty, and elegant, the Royal Oak quickly became a design icon.

In 1977, the Royal Oak was offered in precious mater🐬ials for the first time: yellow gold, white gold, and two-tone. The yellow gold reference 5402BA, like the present example, was produced in a limited run of 736 units, sold between 1977 and 1980. This particular timepiece features a stunning grey dial and a champagne date disc, with the contrasting colors enhancing its sophisticated appeal. With a 39mm diameter known as a 'Jumbo', the timepiece offers a comfortable fit on the wrist, exuding a pleasing heft from its yellow gold case and bracelet. This Audemars Piguet reference 5402BA represents a rare and significant opportunity for discerning collectors to acquire a historically important model from the Royal Oak collection.
