The Heritage

The GA-110TS-1A Grey Orange is a G-Shock model featuring a 55mm case diameter with the iconic GA-110 architecture. Born in 1983 from Kikuo Ibe's revolutionary vision, this tool watch embodies the "Triple 10" philosophy: resistance to 10-meter drops, water resistance to 10 bar, and ten-year autonomy. The model incorporates Casio's proprietary attachment system and is designed for urban durability.
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?

No, the bracelet is integrated directly into the resin case. A standard strap has nothing to attach to. For this model, I work in the atelier: I build a custom strap, calibrated to your watch's geometry.

How does the custom strap service work at the atelier?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from your G-Shock case, study the proprietary Casio attachment system, and craft a hand-soldered adapter that allows installation without compromising the resin integrity.

Which leather do you recommend for the GA-110?

I prefer Japanese waterproof cordovan. This is an urban tool watch, both sporty and refined — cordovan ages beautifully under wear, developing a patina that tells your story. It resists water, sweat, and the scratches that matter.

How long does a well-made strap last?

It depends on the leather and how you care for it. Cordovan lasts years, even eight or ten with proper maintenance. Leather needs air — don't lock your watch away. A light cream now and then, and the leather ages better still.

Why is the GA-110 so tough?

It comes from Kikuo Ibe's vision in 1983: drop resistance from 10 metres, water resistance to 10 bar, ten-year battery life. The 'Triple 10' philosophy — a watch built to survive, not to impress critics. That's why a custom strap must respect the same solidity.
