Audemars Piguet Royal Oak Jumbo Extra-Thin 39 mm 26670ST.OO.1240ST.02 Steel Blue

The Audemars Piguet Royal Oak Jumbo Extra-Thin, reference 26670ST.OO.1240ST.02, stands as one of the most historically resonant luxury sports watches available for sale today. When Gérald Genta sketched the original Royal Oak in 1972, he conceived a 39mm octagonal stainless steel case secured by eight exposed hexagonal screws — a design so bold it redefined what a luxury watch could be. Reference 26670ST.OO.1240ST.02 is Audemars Piguet's modern tribute to that founding vision, reviving the exact 39mm Jumbo dimensions and extra-thin profile that collectors and historians regard as the purest form of the Royal Oak lineage.

The case of the 26670ST.OO.1240ST.02 is crafted entirely from polished and satin-brushed stainless steel, measuring 39mm across — a diameter that feels immediately purposeful on the wrist without the bulk of larger sports references. The alternating surface finishes catch the light in characteristic Royal Oak fashion, and the case transitions seamlessly into the integrated bracelet, a signature architectural detail that remains just as visually arresting today as it was in the watch's inaugural decade. The screw-down crown adds a utilitarian honesty that speaks directly to the watch's avant-garde industrial heritage.

At the heart of the dial is Audemars Piguet's celebrated Petite Tapisserie pattern, a finely hobnailed guilloché texture that appears to shift in tone and depth depending on the angle of light. On this reference the Tapisserie is rendered in a striking blue, a color that has become synonymous with the Royal Oak identity and one that collectors specifically seek when buying a Royal Oak Jumbo online. Applied hour markers and hands in polished steel contrast elegantly against the textured blue ground, maintaining perfect legibility while contributing to the dial's remarkable visual richness.

Power comes from a certified Swiss-tested Audemars Piguet automatic movement, delivering the precise and reliable timekeeping expected of a manufacture of this stature. The extra-thin architecture of the caliber is central to the watch's identity, allowing the case to maintain the slender silhouette that gives the Jumbo its name and its reputation as one of the most wearable high-complications dress-sports watches on the market. The movement is held to the exacting finishing standards that Audemars Piguet has maintained across its manufacture history in Le Brassus.

On the wrist, the Royal Oak Jumbo Extra-Thin 26670ST.OO.1240ST.02 occupies a rare category: a watch that wears as comfortably beneath a shirt cuff at a formal dinner as it does at a weekend lunch. The 39mm footprint, slim case height, and integrated bracelet with AP folding clasp distribute weight evenly and hug the wrist in a way that larger modern sports watches simply cannot replicate. This is the dimension and proportion that original Royal Oak devotees waited decades for Audemars Piguet to reintroduce at scale.
