Strap for Royal Oak Self-Winding 41 Green Camouflage

The Royal Oak's attachment does not follow any industrial standard: it is an integral part of Genta's original design, calculated to extend the case geometry onto the wrist. A strap built to measure on the watch is the answer: <a href="/pages/casati-booking">Casati Milano</a> physically measures the lug dimensions in the atelier and constructs the strap specifically for this reference, ensuring a perfect fit both visually and functionally.

Casati Milano atelier receives the watch by appointment and takes precise physical measurements: lug angle, case curvature, attachment geometry. Only after this hands-on survey does the construction begin — the strap is literally built around the watch. The client chooses leather, colour, buckle or deployant clasp in the atelier, and the final piece is unique to that specific watch.

Alligator with square grain and fine texture is the most coherent choice: the regularity of the scales mirrors the geometric structure of the Tapisserie dial, while the polished finish complements the white gold's reflectivity. For a more contemporary reading, ostrich with its irregular texture introduces a deliberate contrast that softens the architectural rigidity of the Royal Oak. In both cases, the patina the leather develops over time becomes part of the piece's character.

A strap built from first-cut leathers, hand-stitched and fitted with steel or gold hardware can last years while retaining structural and aesthetic integrity, provided basic care is observed: avoid prolonged exposure to water and perspiration, and allow it to dry naturally after use. The patina that develops on quality leather over time is not wear — it is what distinguishes an artisan strap from an industrial one.

Calibre AP 4309 is an in-house movement developed by Audemars Piguet to deliver hours, minutes and seconds with the precision expected of a manufacture that has produced its own calibres for over a century. Fitting an in-house movement in a gemstone reference such as this is a deliberate statement: it reflects Audemars Piguet's philosophy of never separating watchmaking from jewellery-making. The movement is visible through the caseback, ensuring that no side of the watch remains hidden.
