The Heritage

The G-Shock GD-X6900PM-1 is a technical chronograph featuring the 6900 module, embodying the Triple 10 philosophy: 10 bar water resistance, 10-year battery life, and survival from 10-meter drops. The 57.5mm resin case is engineered for extreme durability with triple-layer protection. This urban icon merges military heritage with contemporary 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 I fit a standard strap on the Casio G-Shock 6900 GD-X6900PM-1?

No, the bracelet is integrated into the case. There are no standard lugs where you can attach a strap — the resin construction doesn't allow it. If you want to change the look, the only option is having a custom strap built directly onto your watch.

How does the custom strap process work for this model?

We work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, study how the leather needs to attach to the resin elements, and build the strap by hand. It's work that demands millimetre precision.

Which leather do I recommend for the G-Shock 6900?

I prefer Tuscan vegetable-tanned leather. This watch has a sporty, urban character, and leather ages beautifully, developing a patina that tells the story of wear. If you want something softer and more tactile, suede is equally valid, but it requires more care.

How long does a well-made strap last?

It depends on the leather and how you wear it. Tuscan leather easily handles 5-7 years of daily wear, if treated with respect. Leather ages, darkens, develops creases — not a flaw, but its character. Basic maintenance — avoid standing water, dry after sweat — extends life considerably.

Why was the G-Shock 6900 built with an integrated bracelet?

Kikuo Ibe, the creator, chose this for the "Triple 10" philosophy — resistance to 10 bar and a structure that survives 10-meter drops. The integrated bracelet is part of the protective shell, not an accessory. It's architecture, not aesthetics. That's why changing it takes real skill.
