Strap for Royal Oak Concept GMT Tourbillon Titanium / Black

Not in the conventional sense. The bracelet is integrated into the titanium and ceramic case: there is no standard lug where an off-the-shelf strap can be attached. I build the strap to measure, directly on the watch, in the atelier.

Everything is done 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, study the geometry of the integrated attachment and take measurements from the actual case. There are no templates: every strap is built from scratch on that specific piece.

I recommend naturally aged Barenia. Titanium has a chromatic coolness that Barenia balances with warmth, without softening the Concept's sporting character. Over time it develops a personal patina that tells the story of use — and on a watch like this, that feels right.

With ordinary care, a properly constructed strap easily lasts eight to ten years. Quality leather does not deteriorate: it ages, changes tone, takes the shape of the wrist. I keep it away from water, dry it promptly if it gets wet, and occasionally condition it with a neutral product.

The Concept family was created to push to the extreme what the original Royal Oak began. Combining titanium with ceramic is not a superficial aesthetic choice: these are two materials with very different thermal and mechanical behaviours, and working them together demands a precision that shows in the attachment details. That is precisely what makes every bespoke intervention so complex — and interesting.
