The Heritage
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.

Can you fit a standard strap on the Casio Mudmaster GWG-1000-1A9?
No, the bracelet is integrated into the case and doesn't have standard lugs. A regular strap simply won't fit. What I do in the atelier is create a bespoke strap, designed directly onto your case geometry.
How does a bespoke strap work for the Mudmaster?
We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from your case, study the proprietary attachment and create a precision interface that sits perfectly with the watch, no forcing.
Which leather do you recommend for the Mudmaster?
I prefer Tuscan Vegetable-Tanned Leather for those wanting elegance under pressure: it ages beautifully, resists moisture and mud. For pure sportiness, I choose reinforced NATO Premium — tough, quick-drying, built for the extreme environments this watch was made for.
How long does a well-made strap last?
With conscious use and care, between 5 and 8 years. Vegetable-tanned leather improves over time, developing a patina that tells the story of your wear. The key is cleaning it after mud or saltwater exposure and letting it air dry naturally.
Is the Mudmaster GWG-1000 really built to handle mud and impacts?
Absolutely. I've seen these watches survive drops, submersions and conditions that would wreck any other timepiece. The reinforced resin and steel structure isn't just brutal aesthetics—it's engineering designed to last in genuinely hostile environments.
