The Royal Oak Offshore 26470BA.OO.1000BA.01, seen from the bench

The Royal Oak Offshore represents the sporty evolution of the Audemars Piguet Royal Oak collection. It features the automatic AP 3126/3840 caliber with functions of hours, minutes, small seconds, date, and chronograph. The case presents the characteristic octagonal construction with visible bezel and integrated bracelet.

Frequently asked questions

Can a standard strap be fitted to the Royal Oak Offshore 26470BA.OO.1000BA.01?

No. The bracelet is integrated into the case: there is no standard lug to attach an off-the-shelf strap. This is a deliberate design choice by Audemars Piguet, not a limitation. In my atelier, I build the attachment bespoke, directly on the watch.

How does the bespoke strap service work for this model?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, at Via XX Settembre 15 in Milan. I bring the watch to the bench, take measurements from the actual case, and shape every millimetre of the attachment by hand. I never work from photographs or moulds: the case must be in front of me.

Which leather do you recommend for this Royal Oak Offshore?

I prefer Mississippi alligator with an extra-large scale. The pronounced grain holds its own against the ceramic and yellow gold without being overwhelmed. It is a leather that ages with character, which is exactly what a watch with this direct, sporting temperament calls for.

How long does a well-made strap last?

With quality leather and regular wear, I would count on at least five to seven years before the strap shows signs that genuinely compromise it. Care is straightforward: keep it away from prolonged exposure to water and let it breathe. Quality leather does not deteriorate — it transforms, taking on the creases of the person wearing it.

Did the Offshore really represent a genuine break from the original Royal Oak?

Yes, and not in a subtle way. In 1993 the Offshore arrived as a deliberately outsized statement compared to the calibrated elegance of Genta's Royal Oak. Larger case, more muscular construction, harder edges. I have seen many watches launched as 'evolutions' disappear quickly. This one stayed, because it had something real to say.
