Frequently asked questions

Can you fit a standard strap on the Casio G-Shock 6900 DW-6900NB-1?

No, the bracelet is integrated into the case. The attachment is not a universal standard, so an off-the-shelf strap won't fit. But that's not a limitation—I build a custom strap in the atelier, directly on your watch.

How does the custom strap work for this model?

I work by appointment only at <a href="/pages/casati-booking">atelier Casati Milano</a>. I take measurements directly from your watch, study the geometry of the attachments, and craft a strap that sits perfectly with the resin. No shortcuts.

Which leather do you recommend for the G-Shock 6900?

I prefer Tuscan leather, vegetable-tanned. It has a robust character, ages beautifully, and respects the sport-elegant DNA of this model. If you want technical performance and sustainability, premium regenerated NATO is my second choice.

How long does a well-made strap last?

With serious wear, 5 to 10 years. It depends on care: avoid standing moisture and clean it occasionally. Real leather doesn't die—it ages, developing a patina that tells your wrist's story.

Why is the G-Shock 6900 so distinctive in its class?

Launched in 1995 as the evolution of the legendary 6900 series: three circular eyes, integral resin architecture, built for extreme environments. This isn't aesthetic gesture—it's a statement of resistance. I've seen pieces from that era still intact after decades of real work.

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.
