The Heritage
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.

Can you fit a standard strap on the Bell & Ross Instruments BR05A-BL-ST/SRB?
No, the bracelet is integrated directly into the case. It doesn't have standard lugs that allow a strap to attach. If you want to change the bracelet, you need to come to us: I make a custom strap in the workshop, fitted directly to your watch.
How does the bespoke strap work for this model?
I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from the case, study the transition between the integrated bracelet and the new strap, and hand-shape it so the connection is seamless.
Which leather do you recommend for the Bell & Ross Instruments BR05A-BL-ST/SRB?
I prefer Tuscan leather with vegetable tanning. This watch has a technical, sporty soul: raw leather ages beautifully, develops patina with wear, and keeps the constructive simplicity that defines the BR05. It's the most honest choice.
How long does a handmade strap last?
A properly made strap lasts years. I've seen vegetable-tanned leather hold up through 5, 6 years of daily wear. Leather needs care: wipe it with a damp cloth now and then, keep it dry in winter. After that, it's not deterioration—it's patina. It's alive, it changes with you.
Why does the BR05 have an integrated bracelet?
It's Bell & Ross staying true to the original design: the squared geometry, the bevelled corners, the architectural continuum between case and bracelet follow the "Form Follows Function" philosophy of aircraft instruments. It's not a commercial choice, it's structural. That's why the custom strap must respect every millimetre.
