Strap for Kalpa Donna

No, the bracelet is integrated into the case and the lug attachment is proprietary. A commercial strap won't fit. But I can handcraft you a custom one in the atelier, modelled directly onto the geometry of your rose gold case.

I recommend contacting <a href="/pages/casati-booking">Casati Milano</a> to book an appointment. I take the watch in hand, study the tonneau curve and the proprietary lug specifications, then build the strap piece by piece on your case.

For a watch of this geometric elegance, I favour Mississippi Alligator: its fine grain and warm tone complement the rose gold beautifully, without competing with the tonneau shape. If you prefer something more tactile and relaxed, Barenia ages wonderfully over time.

With daily wear and minimal care, a good leather strap will serve you reliably for 5–8 years. What I love about natural leather is that it doesn't die: it changes texture, it patinas, it tells the story of time. Just wipe it clean with a soft cloth now and then.

It's an intentional design choice: Parmigiani wanted the tonneau case to breathe as a single, uninterrupted form. The bracelet is not a removable accessory—it's part of the architecture. That's why a bespoke strap isn't a compromise; it's the only coherent path.
