Strap for Royal Oak Offshore Selfwinding Music Edition White Gold - Rainbow / Aventurine

Not an off-the-shelf strap: the lug system is an integral part of the case design, following the octagonal geometry of the model in a wholly proprietary way. A strap is entirely achievable, built bespoke directly on the watch by the atelier <a href="/pages/casati-booking">Casati Milano</a>, where every measurement is taken by hand before production begins.

The process begins with an appointment at the atelier, where the craftsman measures the case geometry directly on the client's watch: lug curve, recess depth, exact radius of curvature. From these data, a strap is built that fits the Royal Oak Offshore with precise accuracy, without adapters or compromises. The choice of leather, colour and buckle is made during the consultation, from physical sample collections.

Smooth hornback alligator in slate grey or midnight blue echoes the geometric rhythm of the Tapisserie dial without competing with the diamonds on the bezel. Black or bordeaux box-calf offers an exceptionally fine grain and surface compactness that engages rigorously with the white gold finishing. For those seeking chromatic warmth, ostrich leather in champagne tones creates a luminous and refined contrast.

A strap built from first-grade leathers with hand-stitched seams, given ordinary maintenance — periodic cleaning, protection from prolonged moisture, rotation in use — will accompany the watch for many years without losing structure or appearance. The quality of the lining is equally important: a kid leather or silk satin lining protects the case and preserves the strap's shape over time. A well-crafted bespoke piece improves with wear, developing a patina that reflects the story of the person who wears it.

The Royal Oak Offshore was launched in 1993 as a radical evolution of Gerald Genta's 1972 Royal Oak: larger, more assertive, conceived for those who wanted uncompromising sporting luxury. The 2022 version in 18-carat white gold with a diamond-set bezel is a feminine interpretation that sacrifices none of the original's aesthetic tensions, pairing them with the AP 5909 calibre and a Tapisserie dial that transforms every shift in light into a different effect on the wrist.
