The Heritage

The G-Shock 6900 from the DW series belongs to Casio's line of shock-resistant digital watches. It is powered by the 3230 caliber with perpetual calendar, chronograph, countdown and alarm functions. The DW6900MR1ER reference features a resin construction with a screw-down crown and water resistance.
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 DW6900MR1ER?

No, a standard straight-bar strap does not fit the integrated attachment of the DW6900MR1ER, which is part of the case design. However, a custom-built artisanal strap can be created by measuring the exact specifications of your watch in the workshop. This is precisely the work <a href="/pages/casati-booking">Casati Milano</a> specializes in.

How does the custom strap-building process work for this model?

The craftsman measures the attachment width, lug position and case geometry of your DW6900MR1ER in the workshop. Using these specifications, he constructs a strap that adheres precisely to the watch's unique requirements, with leather and finishing chosen according to your preferences. It is not an adaptation, but true sartorial construction tailored to the object.

Which leather is suitable for the character of the Casio G-Shock 6900 DW6900MR1ER?

The DW6900MR1ER thrives on material honesty and sharp contrasts, making Chromexcel and Horween natural choices: they age beautifully, developing rich patina and increasingly pronounced grain that resonates with the tactical feel of the resin case. Robust vegetable-tanned leathers and technical fabrics also work well, provided they avoid excessive softness or glossy finishes.

How long does a well-made artisanal strap last on a watch like this?

A strap built with care by an experienced craftsman can last many years, often longer than the watch itself. Durability depends on the leather chosen, the construction quality and maintenance: traditionally tanned vegetable leather improves with age if cared for, while more delicate leathers require greater attention.

Why has the Casio G-Shock 6900 remained so iconic since 1995?

The DW6900 has sustained its rebellious appeal because it never attempted to be anything other than what it is: an uncompromising sports instrument with reliable movement, shock-resistant case and aesthetics that speak directly to street and skateboard culture. Its aesthetic and functional coherence has made it timeless.
