The Heritage

The G-Shock GD-X6900MNM-1 is a resin sports watch with a 57.50mm case designed for extreme impact resistance. This model features a non-standard integrated lugs geometry that requires custom strap solutions. The Atelier Casati Milano crafts bespoke leather or technical fabric straps with custom-fitted attachments adapted to the resin case, respecting the technical essence of this iconic timepiece.
Made to Measure

The strap for this watch is made to measure

On the Casio G-Shock 6900 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 on the Casio G-Shock 6900 GD-X6900MNM-1?

No, the bracelet is integrated into the case and the lugs are proprietary — no standard strap will attach. I work at the bench with <a href="/pages/casati-booking">Casati Milano</a> to build a bespoke solution directly on your case.

How does the bespoke strap work for the G-Shock 6900?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a> on Via XX Settembre 15, Milan. I take measurements directly from the case, study the exact geometry of the resin lugs, and craft an interface that aligns perfectly with your watch.

Which leather would you recommend for this model?

I prefer premium suede with a coarse grain and generous thickness. The aesthetic of this G-Shock is military, sporty — it needs a material that breathes this character, not glossy or delicate finishes. Suede hardens with wear and ages beautifully, just like the watch itself.

How long does a well-made strap last?

It depends on how you wear it. A quality leather strap, with ordinary care, lasts 4–6 years of daily wear. The leather patinas, hardens, develops history. If you expose it constantly to salt water or heavy sweat, maintenance needs to be more frequent — but the material ages like your watch does.

Why is the G-Shock 6900 different from other G-Shocks?

It emerged in the '90s as a radical evolution of the form: a larger case, post-industrial geometry, structural resilience designed for extreme impact. It's not an elegant watch — it's built to perform, and that's its beauty. Any personalisation must respect this technical soul, not soften it.
