The Heritage

The G-Shock DW-6900DS-1 belongs to the Casio 6900 series, launched in the 1990s as an evolution of the original G-Shock line. The watch is equipped with the quartz caliber 3230 featuring perpetual calendar, chronograph, countdown and alarm functions. The resin case presents the characteristic three-eye design with digital display and shock-resistant construction.
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 onto the Casio G-Shock 6900 DW-6900DS-1?

No, the bracelet is integrated into the case — it's not a standard lug attachment. A regular strap won't fit. That's why at <a href="/pages/casati-booking">Casati Milano</a> we craft bespoke solutions built directly onto your case's original structure, honouring every detail.

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

We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15. When you come in, I measure directly on your case — so I know every profile and curve. From there we craft a harness that integrates perfectly with the original geometry.

Which leather do you recommend for this model?

For the 6900, I prefer vegetable-tanned Tuscan leather. It has that raw solidity that mirrors the watch's athletic character, ages with real marks, and feels genuinely lived-in. If you want lightness and sustainability, Italian premium NATO made from regenerated recycled fibres offers robustness without compromise.

How long does a well-made strap last?

A quality leather strap accompanies your watch for years. Tuscan leather gets better with time — it collects scratches like a map of your life. Care is simple: dry it if it gets wet, every so often massage it with neutral balm. Leather ages, it doesn't die.

Why is the DW-6900DS-1 considered special in G-Shock history?

Launched in 1995, the 6900 wrote modern G-Shock history — three circles on the dial, genuine military durability, aesthetics that captured Tokyo street skaters and NASA engineers alike. It's one of those watches that redefined what 'indestructible' means in urban culture.
