The Heritage

The G-Shock GA-110-1B Black features a resin case measuring 55mm in diameter with high readability dial. This model requires a customized millimetric adapter for strap attachment due to its integrated non-standard lug system. The GA-110 represents the evolution of G-Shock technology since its 1983 inception.
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 to a Casio G-Shock GA-110?

No, the bracelet is integrated into the resin case. The attachment is proprietary and a standard strap won't fit. At <a href="/pages/casati-booking">Casati Milano</a>, I build a custom strap directly onto the geometry of your case.

How does the custom strap work for this model?

Come to the atelier by appointment at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from your case, study the integrated attachment, and craft a strap that fits perfectly. It's precision millimetre work, customised for your watch.

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

I prefer Tuscan Supreme Leather. This watch has a robust, sporty character, and vegetable-tanned leather that ages well respects that solidity. The leather develops a patina over time, creating elegant contrast with the resin case.

How long does a well-made strap last?

With daily wear, quality leather lasts 4-5 years before showing significant wear. It depends on how you treat it: avoid prolonged moisture, let it dry naturally if wet. Leather ages and develops character—this isn't a flaw, it's part of the story.

Why does the GA-110 have an integrated bracelet?

Kikuo Ibe, the original designer, conceived the case architecture as a single block to maximise impact resistance. That resin wrapping your wrist is part of the protection structure. It's a conscious trade-off between indestructibility and versatility—which is why the custom strap solution exists.
