The Heritage

The BR05 Stainless Steel Skeleton Blue is a square-cased instrument watch by Bell & Ross with integrated bracelet, exemplifying the brand's "Form Follows Function" philosophy in contemporary sports design. The case features rounded corners and integrated lug system. This model represents the evolution of tool watch aesthetics meeting refined urban design, delivering instrumental legibility without compromise.

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 I fit a standard strap on the Bell & Ross Instruments BR05A-BLU-SKST/SRB?

No, the bracelet is integrated into the case. A standard strap has no compatible lugs. However, I craft a custom strap directly onto your watch, tailored to the specific geometry of the case.

How does the custom strap work for this model?

I receive you at the atelier in Milano, at Via XX Settembre 15. I take measurements directly from the case and study the proprietary attachment points. Then I build the strap, hand-sewn, perfectly fitted to your BR05. You can book here: <a href="/pages/casati-booking">Casati Milano</a>.

Which leather do you recommend for the Bell & Ross Instruments BR05A-BLU-SKST/SRB?

For this watch, I prefer Mississippi Alligator. It has the compactness that dialogues well with the urban, sportive geometry of the square case. It ages with elegance, and the technical character of the model deserves leather that makes no concessions.

How long does a well-made strap last?

With daily care, a handcrafted strap easily lasts 5-7 years. It depends on use: if you expose it to intense sun and water without protection, it ages faster. Good leather doesn't wear out, it patinas. I suggest you let it breathe and condition it once a year.

Why does the BR05 have an integrated bracelet? Isn't that a disadvantage?

Quite the opposite. Bell & Ross chose this solution to create an architectural continuum: the case and bracelet are conceived as a single body, not as assembled parts. The disadvantage is you don't change the strap in two seconds. The advantage is structural solidity and visual identity that I don't compromise with makeshift adapters.
