The Heritage

The G-Shock DW-6900 represents one of the classic configurations of the Casio G-Shock line, characterized by the three circular dial layout. It features the 3230 quartz caliber with chronograph, countdown, alarm, and perpetual calendar functions. The resin construction ensures shock resistance according to G-Shock standards.
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 a standard strap be fitted to the Casio G-Shock 6900 DW-6900SC-8ER?

No, the bracelet is integrated directly into the resin case. The attachment is not a standard fitting — a regular strap won't connect. This is why we work in the atelier: I build a bespoke adapter directly on your watch.

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

I work with the <a href="/pages/casati-booking">Atelier Casati Milano</a>, by appointment only. I take measurements of the case geometry, study the anchoring system, and craft the strap calibrated for your watch. It's not a quick modification — it's craftsmanship.

Which leather would you recommend for the DW-6900SC-8ER?

I prefer hand-tanned Tuscan leather. This watch was born for urban, military, sporting use — it has a raw and honest character. A leather that ages visibly, that develops patina over time, tells the same story as the watch.

How long does a well-made strap last?

With quality leather and minimal maintenance — occasional cleaning, no excessive water — it lasts years. I've seen Tuscan leather straps still wearable after six or seven years of daily use. Good leather doesn't disappear: it ages, builds patina, becomes more beautiful.

Why is the G-Shock 6900 still relevant after nearly 30 years?

Because the design solves a real problem: extreme protection without aesthetic compromise. The round case with hexagonal guard isn't decorative — it's engineering. Military personnel, skateboarders, collectors still choose it because it does what it promises to do.
