The Heritage

The G-Shock GA-110 belongs to Casio's line of shock-resistant digital-analog watches. It features the 5081 quartz caliber with world time, perpetual calendar, chronograph, countdown and alarm functions. The resin case offers shock resistance and water resistance up to 200 meters.
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 the Casio G-Shock GA-110 GA-110SL-8A?

No, a standard strap with straight spring bars is not compatible with this model because the lug attachment is integrated into the case structure. The solution is a bespoke strap: handcrafted by <a href="/pages/casati-booking">Casati Milano</a>, it is moulded directly to your watch, respecting the resin architecture and completely replacing the original fabric element.

How does the bespoke strap construction process work for the GA-110?

The craftsman at <a href="/pages/casati-booking">Casati Milano</a> takes precise measurements of the lug attachment on-site, measuring curves, thickness and tension points on your wrist and case. The strap is then handmade in parallel, following those specifications. The moulding respects the entire geometry of the resin without forcing or compromising fit.

What type of leather suits the character of the Casio G-Shock GA-110 GA-110SL-8A?

Leathers with strong vegetable grain—natural anilines, aged cordovan, vintage hide—enhance the industrial aesthetic without softening it. Avoid glossy finishes; choose neutral tones (natural brown, deep black, slate grey) where texture becomes the protagonist. A leather that develops patina over time amplifies the narrative character of a watch designed to age like a tool.

How long does a well-made bespoke strap last?

A strap crafted by <a href="/pages/casati-booking">Casati Milano</a> with hand stitching and reinforced stitchwork lasts decades. Longevity depends on use and care: quality leather ages nobly, developing patina and character. Unlike industrial straps, a handmade piece can be reconditioned or completely regenerated by the craftsman.

Why has the Casio G-Shock GA-110 remained iconic for forty years?

Because it has never betrayed Kikuo Ibe's original vision: shock resistance as aesthetic philosophy, not merely functional specification. The GA-110SL-8A, with its translucent dial and 55mm diameter, maintains that uncompromising brutality while enhancing it with advanced movement (perpetual calendar, chronograph, world time) and a global community of tactical users. It is a language that does not age.
