The Heritage

The G-SHOCK GD-X6900HT-2 Heathered Purple features the iconic 6900 module with a 57.5mm resin case and characteristic three-display layout. This model, part of G-Shock's lineage since 1983, maintains extreme durability through reinforced construction. Custom strap solutions respect the proprietary integrated spring-bar attachment system while preserving the original industrial design.
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 on the Casio G-Shock 6900 GD-X6900HT-2?

No, the bracelet is integrated into the case with proprietary attachments. A standard strap won't fit. But I can build one bespoke in the workshop, directly on your watch, respecting the original geometry of the reinforced resin.

How does the bespoke strap work for this model?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from the case, study the integrated spring-bar attachments, and create a solution that fits perfectly without compromise.

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

I choose technical, water-repellent leathers with a sporty yet versatile character. I prefer vegetable-tanned options that age beautifully and support the industrial style of the watch, without softening its visual toughness.

How long does a well-made strap last?

A properly crafted strap lasts 5-7 years of intense use, and longer with care. Technical leather ages with elegance, developing patina. It depends on how you live with it—it's an object that changes alongside you.

Why is the 6900 module so distinctive compared to other G-Shocks?

The sculptural case and three-display layout make it instantly recognisable. Born from Kikuo Ibe's vision in 1983, it represents the apex of "Industrial Toughness" aesthetics. It conquered Navy SEALs and mountaineers: that extreme resilience shows, it feels right.
