Frequently asked questions

Can I fit a standard strap on the Casio G-Shock GA-110 GA-110BR-5A?

No, the bracelet is integrated into the case and the lugs are proprietary Casio attachments. A standard strap won't fit. For this model, I craft a custom strap directly in the atelier, shaped to your individual watch.

How does the custom strap process work?

Come to <a href="/pages/casati-booking">Casati Milano</a> by appointment. I take measurements directly from your case, study the proprietary lugs and hand-craft the strap. It's the only way to respect the geometry of this G-Shock.

Which leather do I recommend for the GA-110?

I prefer reinforced cordura or waxed Italian canvas. This watch is brutal, sporty, built to endure. The leather must answer back: materials that age well under stress, that don't demand formal elegance but intelligent durability.

How long does a well-made strap last?

With normal wear, 5-7 years at least. The sport leather I use is designed to move with your wrist, not sit idle. If you treat it right – don't soak it in sweat, let it air dry – it ages beautifully, developing a patina that tells the story of time together.

Why is the GA-110BR-5A case so large?

Casio designed it that way in 1983 and never stopped. The 55mm case with that "Hyper Complex" design isn't vanity: it's function. It houses the technology, protects the movement, tells you this isn't an office watch. It's architecture on the wrist.

The next step

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

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
