The Serpenti 102099, seen from the bench

The Serpenti Tubogas Two Tone Black Diamond Double Tour is a 35mm integrated bracelet watch in pink gold and stainless steel, embodying Bulgari's iconic design heritage since 1948. This model features a two-tone construction with black diamond elements and a double tour wrist configuration. The integrated bracelet architecture requires specialized strap solutions to maintain its distinctive aesthetic integrity.

Frequently asked questions

Can you fit a standard strap to the Bulgari Serpenti 102099?

No, the bracelet is integrated into the case. There is no standard lug attachment, so a regular strap won't fit. What I do in the atelier is craft a custom strap directly onto the case, honouring the Serpenti's original geometry.

How does the bespoke strap process work at Casati Milano?

We work by appointment only. You meet me in the atelier, and I take measurements directly from the case. <a href="/pages/casati-booking">Casati Milano</a> studies the integrated attachment and builds a strap that locks in without strain, preserving the fluidity of the design.

Which leather would you recommend for the Bulgari Serpenti 102099?

I prefer Mississippi Alligator in antique rose or luminous ash Swift. The Serpenti breathes elegant sensuality, not sportiness. A satin-finish leather that ages gently seems the only choice that honours the warmth of rose gold and the soul of the watch.

How long does a well-made strap last?

With thoughtful wear, at least 8–10 years. Everything depends on how you treat it: avoid prolonged moisture, swim carefully, remove it each evening. Noble leather ages, develops patina, darkens. It doesn't die—it tells the story of your wrist.

Why was the Serpenti created and what sets it apart?

Since 1948, Bulgari designed it as a fusion of jewellery and watchmaking. It's not conceived as a watch with a separate strap—it's an organic whole, a shape that moves. That's why touching its balance with a standard strap would be a failure of respect toward the object.

The next step

The right strap isn't chosen. It is built, together.
