The Heritage

The Casio G-Shock DW-6900MF-1 is a digital watch released in 1995, featuring three digital displays, extreme durability, and an integrated resin case with bracelet. The model combines compressed resin construction with a specialized integral attachment system designed for technical resistance and structural integrity.
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 I fit a standard strap to the Casio G-Shock 6900?

No. The bracelet is integrated into the case and has no universal attachment points. A standard strap won't fit. I recommend <a href="/pages/casati-booking">Casati Milano</a>: there I build custom straps directly onto your watch, respecting its original architecture.

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

Visit <a href="/pages/casati-booking">Casati Milano</a> by appointment at Via XX Settembre 15 in Milan. I measure directly from your case, study the proprietary attachment system and craft the strap by hand, moulding each connection to sit perfectly without compromising the case.

What leather do you recommend for this watch?

I prefer robust, oiled vegetable-tanned leather. The G-Shock 6900 was born on the street in sports environments, and it deserves leather that ages visibly alongside its technical character: dark patina, vivid grain, no artificial shine. It's the right pairing between resin and genuine hide.

How long does a well-made strap last?

It depends on use and care. Quality leather lasts 5–7 years of daily wear, often longer if treated with respect: dry it when wet, avoid direct heat, oil it occasionally. It ages beautifully; leather improves over time, stitching holds without complaint.

Why is the G-Shock 6900 considered a historic piece?

When Casio launched it in 1995, it redefined what durability and sports watch design meant. It changed street watches: three displays, water resistance, robust bracelet. Since then, everyone from hip-hop artists to military divers has worn it without the design ever wavering. It's stayed true to itself for three decades.
