The Heritage

This timepiece represents Italian sculptural watchmaking where the bracelet becomes an integral part of the watch structure. Custom strap solutions require specialized craftsmanship to respect the organic geometry of the curved case.
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 102780?

No. The Tubogas bracelet is integrated into the case — there is no conventional lug attachment. A standard strap has nowhere to attach. What you can do is contact the <a href="/pages/casati-booking">Casati Milano Atelier</a>: I craft the strap bespoke, directly on your case, with sculptural lugs that respect the geometry of the Serpenti.

How exactly does the bespoke strap work for the Serpenti?

I book an appointment at the atelier in Via XX Settembre, Milan. I take measurements directly from your case — the curve, the thickness, the exact position where the strap integrates. Then I work at the bench with leather chosen together with you, shaping the lugs with precision so everything flows as the serpent itself does.

Which leather do I recommend for this model?

Mississippi Alligator lacquered. It has that controlled gleam and that solidity which speaks well with the Serpenti's steel — it doesn't compete with the case, it accompanies it. If you prefer something softer and more vintage, hand-aged Barenia ages beautifully over time, acquiring patina. For the character of this watch, I set aside skins that are too delicate.

How long does a well-made strap last?

It depends on wear and care. A strap in good leather, with well-crafted lugs, lasts 5–8 years of regular wear. The leather ages — it darkens, it develops patina, it breathes. That's not a defect: it's a record of use. I recommend keeping the strap away from excessive moisture and letting it 'breathe' when you're not wearing it.

Why is the Serpenti 102780 so different from standard strapped watches?

Because it's not a watch with a strap attached: the bracelet is architecture of the case itself. It was born in 1948 as a sculpture for the wrist — that tubular sinuosity is designed to move with the body. Anyone choosing to change its strap must understand this: you're not adding an accessory, you're inhabiting the same form with another language of leather. That's why I insist on bespoke work and quality: the new strap must speak the same respect.
