Frequently asked questions

Can you fit a standard strap on the Casio G-Shock 6900 DW-6900MF-4?

No, the bracelet is integrated into the case — there's no proprietary attachment for a standard strap. I've seen many try: it doesn't work. To change the strap, you need a bespoke solution built directly onto this case's geometry.

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

I work at the <a href="/pages/casati-booking">Atelier Casati Milano</a>, by appointment only. I measure the case with precision, design custom attachments, and craft the strap in the workshop. It's a process that takes time — not something done over the phone.

Which leather do you recommend for the DW-6900MF-4?

I prefer raw Tuscan leather. This G-Shock was born for the street, for real use — not to stay pristine in a display case. A robust leather that ages well suits the sporty character of the resin case, without leaning towards elegance that doesn't belong.

How long does a well-made strap last?

It depends on use and care. A quality strap, worn mindfully, holds up well for 5-7 years. Leather ages, develops patina, and I prefer watches that show the passage of time. Dirt, scratches, marks — they become part of the piece's story.

Why does the G-Shock 6900 deserve a bespoke strap?

This model was born in the '90s as a genuine tool, not as fashion. Translucent red resin, 53mm case, three-eye design — it's visible solidity. A custom strap doesn't soften it; it respects it: transforms a sports instrument into an object that speaks of who chooses it.

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.
