The G-Shock GA-110 GA-110SG-4A, seen from the bench

The G-Shock GA-110 is part of Casio's analog-digital collection with a quartz movement caliber 5146. The watch integrates chronograph, countdown, alarm, perpetual calendar and world time functions. The resin case features the characteristic shock-resistant design of the G-Shock line with a combined analog and digital display.

Frequently asked questions

Can I fit a standard strap on the Casio G-Shock GA-110?

No, the bracelet is integrated into the case with a proprietary attachment. A commercial strap won't click on. That's why I build one bespoke directly on your watch, respecting the resin geometry and the original anchor points.

How does the bespoke strap work at Atelier Casati Milano?

It's genuine bespoke tailoring. Bring your GA-110SG-4A to <a href="/pages/casati-booking">Casati Milano</a>, by appointment at Via XX Settembre 15, and I take measurements straight from the case. I design custom adapters and build the strap according to your choice of material and finish.

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

Tuscan leather, vegetable tanned. This watch is sporty but graphically bold, and natural leather creates an elegant contrast with the aggressive resin geometry. It ages beautifully, develops patina over time, and reinforces the technical character of the piece.

How long does a well-made strap last?

With excellent vegetable-tanned leather, 4-5 years of intense daily wear. Duration depends on your care: dry it after rain, nourish the leather occasionally with neutral wax. Well-treated leather doesn't crack—it simply deepens in colour and texture.

Why is the G-Shock GA-110 different from other sport watches?

Since 1983, Casio built this model as a statement: shock-resistance as design language, not afterthought. The layered resin case at 55mm isn't trying to be elegant—it *is* elegant precisely because it's honest. Function shapes form here, and a custom strap in natural leather makes that philosophy even clearer.

The next step

The right strap isn't chosen. It is built, together.
