Strap for GA-110TS-8A2 Grey Blue

No, the bracelet is integrated into the case — there's no lug attachment for standard straps. The GA-110's architecture is entirely proprietary. To change the strap, I craft a custom one directly on the watch, in the atelier.

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from the case, study the interface between resin and attachment geometry, and build the custom strap that fits perfectly. No compromises, only artisanal precision.

I prefer Tuscan Premium Leather for this model. It has the right character: ages beautifully, breathes with sport, and its natural grain dialogue with the GA-110's sculptural industrial aesthetic. The controlled firmness handles impact too.

With conscious care, leather lasts years — often 4–5 years of intensive use. What matters is exposure to sweat and water: I suggest drying it after training. As it ages, leather develops patina and character — it becomes even more personal.

The octagonal geometry and sculptural design of the GA-110 create a complex interface between resin and attachment. It's not a conventional watch. I've seen many failed attempts: it requires millimetre-perfect tailoring, which only the atelier can deliver.
