The ref 6005BA breaks away from the iconic octagonal silhouette of the original Royal Oak, embracing a bold square case design. Introduced during the experimental 1980s, a period when watchmakers pushed creative boundaries with varying results, this piece stands out while still honoring the Royal Oak’s signature elements, such as the integrated bracelet and Petite Tapisserie dial.
Its quartz movement features an unconventional time-setting method—using a small pin to press a discreet button hidden within the crown. This rare design twist, combined with its distinctive shape, makes the Royal Oak Square an eye-catching choice for collectors seeking a rare and unique variation of the legendary Royal Oak.
