The Heritage

The GA-110TS-8A2 Grey Blue is a G-Shock model featuring a 55mm octagonal resin case with integrated lugs that require custom strap adaptation. This iconic tool watch, descended from Kikuo Ibe's 1983 design, combines contemporary technical robustness with distinctive Neo Hyper geometry. The integrated resin attachment system necessitates precision craftsmanship for proper strap compatibility.

Made to Measure

The strap for this watch is made to measure

On the Casio G-Shock GA-110 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 Casio G-Shock GA-110 GA-110TS-8A2?

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.

How does the custom strap work for the GA-110?

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.

Which leather do you recommend for the Casio G-Shock GA-110?

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.

How long does a well-made strap last?

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.

Why does the GA-110 require artisanal intervention for the strap?

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.
