Born from the bold design language introduced by Gérald Genta in 1972, this rare square Royal Oak reference 6009ST brings a fascinating variation to the legendary lineage. Produced in notably limited quantities, the reference stands out for its crisp geometric form, blending the iconic industrial cues of the Royal Oak with a more architectural and unconventional case profile.

The anthracite grey dial features the signature Petite Tapisserie texture, its grid pattern interacting dynamically with changing light, a hallmark of Audemars Piguet’s most recognizable creations. The minimalist baton markers and slender hands emphasize legibility while preserving a restrained and contemporary elegance. The “QUARTZ” marking positions the piece firmly in the avant-garde era of AP’s willingness to experiment with both design and technology.

Crafted in robust stainless steel, the multi-faceted case is sharply defined, its integrated bracelet showcasing the alternating satin and polished finishing that has become synonymous with the Royal Oak identity. The angular silhouette reinforces the reference’s distinctive character while paying clear tribute to Genta’s original design codes.

Identified by case number B32350, this example represents a seldom-seen chapter in the evolution of the Royal Oak, a collector’s piece prized for its rarity, its unmistakable aesthetic presence, and its role in extending the iconic Royal Oak architecture beyond its foundational octagonal form.

A charismatic and unconventional interpretation of one of the most influential watch designs ever created, this Royal Oak ref. 6009ST offers a compelling opportunity for the enthusiast drawn to the more discreet yet highly collectible corners of the Audemars Piguet universe.
