Building upon the merits of these two remarkable designs, the brand unveiled its first Royal Oak perpetual calendar in 1983, the referenc♎e 5554.

In 1986, the Royal Oak perpetual calendar underwent a captivating transformation with the introduction of the skeletonised dial edition, reference 25636.
