The Heritage

The G-Shock DW-6900HM-2 belongs to the 6900 series, the digital line introduced by Casio in the 1990s. It features the caliber 3230 with perpetual calendar, chronograph, countdown and alarm functions. The construction follows the G-Shock standards with a resin case designed to withstand shocks.
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-6900HM-2?

The DW-6900HM-2 features an integrated attachment built into the case, which is incompatible with standard straight-bar straps. A custom strap does exist: <a href="/pages/casati-booking">Casati Milano</a> takes precise measurements directly from your watch and hand-crafts an artisanal strap tailored to your case's specific geometry.

How does the custom strap construction process work for this model?

The craftsman at Casati Milano examines the watch, records the precise coordinates of the attachment points and the integrated lug geometry. He then hand-builds the strap in leather or noble materials following these measurements, ensuring perfect fit and uniform tension distribution without risk to the case.

What type of leather suits the character of the G-Shock 6900 DW-6900HM-2?

Vegetable-tanned leather is the most coherent choice: natural patina and authentic grain document usage without betraying the watch's urban austerity. Waxed canvas and reinforced cordura in neutral tones also amplify the case's radical aesthetic without decorative excess.

How long does an artisanally hand-crafted custom strap last?

A strap made by <a href="/pages/casati-booking">Casati Milano</a> in vegetable-tanned leather with hand-sewn construction lasts 5-8 years of daily wear, developing patina over time. Leather quality and hand-stitching ensure repairability: the strap can be restored or reconditioned without requiring complete replacement.

Is the G-Shock 6900 DW-6900HM-2 really the watch worn by Jay-Z and John Mayer?

Yes, the G-Shock 6900 has become a cultural symbol of authenticity in street style precisely because its technical specifications—certified shock resistance, real durability, reliable movement—are independent of luxury narratives. The DW-6900HM-2, with its metallic blue livery, amplifies this uncompromising philosophy without sacrificing functional substance.
