Strap for Royal Oak Concept GMT Tourbillon Titanium / Green

Not in the conventional sense. The bracelet is integrated into the case: there are no standard lugs to attach a regular strap. If you want to wear this watch on leather, the only option is a fully bespoke attachment, shaped directly around the case geometry.

I work exclusively by appointment 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 build every component of the attachment by hand. I don't use generic templates: each strap is made for that specific piece.

On a watch with a titanium and ceramic case, this technical and geometric, I prefer natural vegetable-tanned Tuscan leather. It has a firm texture that works well with the angular architecture of the Concept, and it ages developing a personal patina that no synthetic material can replicate. Mississippi alligator with wide scale is the alternative for those who want something more textural and bold.

With quality leather and solid construction, I expect at least five to eight years of regular use. Care is straightforward: keep it away from prolonged water exposure and condition the leather every few months with a proper cream. Over time the leather doesn't deteriorate, it transforms: it develops character, marks of use, its own history.

The Concept is not an evolution of the classic Royal Oak, it is a different direction entirely. The skeletonised case displays the movement as a visual element rather than concealing it. Titanium and ceramic together produce a result that feels unlike any other material: light, cold, with an unexpected hardness. I have had the chance to handle it several times, and each time it communicates technical intent before anything else.
