The Heritage

The Bulgari Serpenti Tubogas Silver Large is an iconic watch inspired by Roman symbolism, featuring the distinctive integrated tubular Tubogas bracelet that has defined the model since 1948. The watch combines precious materials with exceptional technical craftsmanship, representing both a horological and aesthetic achievement. Milano Straps offers bespoke strap customization through Atelier Casati Milano, utilizing premium leather selections to complement this luxury timepiece.
Made to Measure

The strap for this watch is made to measure

On the Bulgari Serpenti 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 you fit a standard strap on the Bulgari Serpenti 101828?

No. The Tubogas bracelet is integrated into the case: there's no conventional strap attachment. I've seen many owners look for one. In the atelier, I craft a bespoke strap directly onto your case's geometry, without modifying the watch.

How does the bespoke strap work for the Serpenti?

We work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment. I take measurements directly from your case — the fluidity of the Tubogas can't be grasped from a distance. Every detail is built at the bench, for you.

Which leather do you recommend for this model?

I prefer polished Mississippi Alligator. It has the density to match the sensual, decisive character of the Serpenti — that sinuousness deserves a leather that doesn't flatten. Alligator ages beautifully; scratches become patina.

How long does a well-made strap last?

With conscious use, 5 to 7 years. It depends on how you treat it: avoid prolonged water exposure and keep it away from direct heat. A good leather, cared for, tells the story of time passing — and that story is part of its beauty.

Why does the Serpenti have an integrated bracelet?

It's a Bulgari construction choice rooted in history: the Tubogas, born in the 1940s, is a continuous tubular geometry requiring horological precision. A fixed bracelet preserves that sculptural integrity. When you change the leather, you start again from the true measure of the case.

The next step
