The Heritage

The Bell & Ross Heritage Ceramic is a 39mm instrument watch featuring a high-tech ceramic case made from sintered zirconium oxide. It combines aviation watchmaking design with contemporary aesthetics and scratch-resistant ceramic construction. The integrated bracelet architecture requires custom lug attachments developed by specialized artisans for seamless integration.
Made to Measure

The strap for this watch is made to measure

On the Bell & Ross Instruments the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can a standard strap be fitted to the Bell & Ross Instruments BRSHERITAGESCA?

No, the bracelet is integrated directly into the ceramic case. The attachments are proprietary and a conventional strap simply won't fit. For this kind of watch, I craft the strap bespoke in the atelier, shaping the attachment to match your case's geometry.

How does the bespoke strap service work for this model?

I invite you to <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, study the proprietary attachment, and develop the strap by hand-stitching it according to proper technique. It's the only way to achieve perfect aesthetic and functional continuity with the ceramic.

Which leather do you recommend for the Bell & Ross Instruments BRSHERITAGESCA?

I prefer Tuscan leather with vegetable tanning. Its robustness and natural patina dialogue well with the technical rigour of the ceramic. If you're after something more refined and minimal, anthracite-grey suede offers an elegant contrast while maintaining the model's sporty character.

How long does a well-made strap last?

It depends on use and care. A good vegetable-tanned leather withstands 4–6 years of daily wear, longer if you treat it with attention. Leather ages consciously: it develops patina, softens, tells the story of whoever wears it. It's the opposite of disposability.

Does the ceramic on the Bell & Ross require anything special in the strap?

Ceramic is hard and allows no mechanical error in the attachment. The tool I use to shape the strap must be precise to a tenth of a millimetre, otherwise the geometry won't match. There is no "standardisation" for this work—each attachment is unique, hand-stitched to your specific case.
