Strap for Golden Ellipse 5738 White Gold / Japanese Prints

No. The bracelet is integrated into the case — there are no traditional lugs to attach a standard strap. The fitting is an intrinsic part of the original design. Any work on this watch therefore requires a strap built specifically for it, at the atelier.

I work on this model by appointment only, at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15, Milan. I bring the watch to the bench, take measurements directly from the case, and build each attachment by hand, millimetre by millimetre. There is no off-the-shelf solution — every strap is made for that specific piece.

I prefer Veau Swift. Its fine, compact grain works well with the geometric purity of the white gold case without overpowering the elliptical silhouette. For colour, I always lean towards midnight blue or pearl grey — they remain neutral against the form, which is already a statement in itself.

With basic care — keeping it away from water and letting it breathe between wearings — a quality leather strap easily lasts five to six years. The leather ages, developing a personal patina that reflects the wearer. That is not a flaw; it is what sets a living material apart from a synthetic one.

It is the only one from the maison conceived around a mathematical principle: the golden ratio, the 1:1.618 proportion that governs the case geometry. Born in 1968 as a formal statement, it is neither a sports watch nor a complicated piece. From my years at the bench, I have found that those who choose it are looking for something precise — not visibility, but a coherence between the form and the person wearing it.
