Audemars Piguet Royal Oak Offshore 15720ST Diver Strap Guide
The Audemars Piguet Royal Oak Offshore 15720ST is the third-generation Offshore Diver, relaunched in 2021 with a new movement, refined case proportions, and an interchangeable quick-change rubber strap system that lets owners switch straps with a single click rather than tools. Produced across a growing range of dial colours including khaki green, grey and blue, every reference shares the same stainless steel case, screw-locked crowns and 300m water resistance that have defined the Diver family since the original 15703ST.

MIDAS straps are designed as a direct-fit aftermarket replacement, compatible with the factory end links, so there's no compromise swapping away from the factory strap.

About MIDAS
MIDAS was founded in London in 2019 with a simple goal: to create a better alternative to the OEM Audemars Piguet Royal Oak Offshore strap. The factory strap is expensive, stiff and uncomfortable over time. For a watch as bold as the Royal Oak Offshore, we felt collectors deserved better.
We set out to create a premium aftermarket AP rubber strap that is more comfortable, more affordable and available in colours that do justice to the watch. Inspired by the world of performance cars, from Porsche GT racing to Ferrari, every MIDAS strap is designed to complement the bold character of the Royal Oak Offshore.

No. This family comes on a rubber strap from the factory, so your existing OEM end links transfer directly to a MIDAS strap.

Trusted by Collectors
I have bought straps from another brand costing almost twice as much, but these are just as good, if not better. They are very comfortable, fit perfectly and are easy to swap. Highly recommended.
I first bought a black strap because the OEM rubber felt too stiff. MIDAS straps are much more comfortable, and I prefer the slimmer profile. I chose something bolder for my second purchase.
A great product and buying experience. My Diver had become a little boring, but this strap gave it a fresh look and much more wrist time. Fast shipping and excellent communication throughout.
I wanted a replacement after my OEM strap cracked. I did not expect an aftermarket AP rubber strap to feel this good. It is more flexible, grips well and matches the dial perfectly.
