The Serpenti 102123, seen from the bench

The Bulgari Serpenti 102123 is an iconic timepiece featuring a two-tone rose gold and stainless steel bracelet with interlocking coils. The model is characterized by a sinuous snake-inspired design that wraps around the wrist. This Serpenti watch requires a bespoke approach with custom-fitted integrated lugs to harmonize with the case geometry, crafted using premium leathers to maintain the balance between precious materials and comfort.

Frequently asked questions

Can I fit a standard strap to the Bulgari Serpenti 102123?

No, the bracelet is integrated into the case and uses a proprietary attachment. A standard strap won't fit. What I do in the atelier is craft a bespoke strap directly to your case's specific geometry, modelling it by hand.

How does the bespoke strap work for the Serpenti?

We work only by appointment at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15. I take measurements directly from your case, analyse the original attachments and build the tailored strap that integrates perfectly with your watch's geometry. It's the proper way for an instrument like this.

Which leather do I choose for the Bulgari Serpenti 102123?

I recommend Mississippi alligator. This model carries an elegance and sensuality at once, and alligator gives that almost liquid surface, that fluidity which mirrors the sinuous soul of the Serpenti. It's leather that honours the design without competing with it.

How long does a well-made strap last?

With ordinary wear and careful maintenance — gentle cleaning now and then, away from heat — a quality leather strap lasts between 5 and 7 years. And it ages well: the patina that forms is part of its story, becomes richer, more personal. It doesn't deteriorate, it deepens.

Why is the Serpenti such a particular model?

It was born in 1948 as a symbol of seduction and transformation: the interlocking spiral that wraps around your wrist is not a detail, it is the language of the design itself. When I work on a strap for a Serpenti, I respect that geometry, that intention. I'm not trying to change the watch, I'm trying to complete it.

The next step

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