The Heritage

The Casio G-Shock Mudmaster GG-1000GB-1A is a 55mm technical timepiece designed for extreme resistance to mud, dust and vibrations. Featuring a complex case architecture and proprietary integrated bracelet attachment system, this model embodies the "Absolute Toughness" philosophy. Custom strap solutions by Atelier Casati Milano are engineered to respect the watch's structural integrity while ensuring optimal wrist comfort.
Made to Measure

The strap for this watch is made to measure

On the Casio Mudmaster 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 I mount a standard strap on the Casio Mudmaster GG-1000GB-1A?

No, the bracelet is integrated into the case and the attachment is Casio proprietary — a standard strap won't fit. What I do in the atelier is build a custom strap directly on your case, respecting the model's geometry.

How does the custom strap process work at Casati Milano?

We work by appointment only. Bring me the watch at the atelier, I study the proprietary attachment system and take measurements directly from the case. From there, I build the strap that fits perfectly. You can book a consultation at <a href="/pages/casati-booking">Casati Milano</a>.

Which leather do I recommend for the Mudmaster?

I prefer reinforced technical leathers or our Italian NATO Premium regenerated fibre — our sustainable high-performance material. This watch is pure sporting function, it doesn't need delicacy. The strap must withstand whoever actually wears it.

How long does a well-made strap last?

With proper care, 4–6 years of heavy use. Leather ages beautifully, it develops a patina, it conforms even more to your wrist. If you protect it from excessive moisture when you're not wearing it, it lasts even longer.

For the GG-1000GB-1A, does it make sense to customise the strap if the case is already so imposing?

It absolutely does. This watch is heavy and voluminous — the right strap makes the difference between wearing it well and enduring it. With a custom strap, the bulk balances better on your wrist and comfort changes everything. It's a matter of tailoring.
