The Heritage
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.

Can a standard strap be fitted to the Casio G-Shock 6900 DW-6900SN-4ER?
No, the strap attachment is integrated into the case and does not follow universal standards. A standard strap cannot be mounted; instead, you can commission a bespoke strap constructed specifically for this watch at <a href="/pages/casati-booking">Casati Milano</a>, where precise measurements are taken and the leather is sized and crafted in-house.
How does the bespoke strap creation process work?
During your appointment at <a href="/pages/casati-booking">Casati Milano</a>, the watch is examined to determine the exact geometry of the attachment, seat depth, entry angles, and visual balance with the case. Leather and hardware are then selected, and the strap is constructed specifically for your 6900, ensuring a perfect fit and harmonious transition between case and leather.
Which leather type best suits the Casio G-Shock 6900 DW-6900SN-4ER?
Leathers with high grain, such as textured calf or rough suede, reflect the technical massiveness of the watch. Matte finishes and vegetable-tanned leathers that develop patina over time work perfectly with the functionalist, grey aesthetic of the 6900. High gloss finishes are discouraged: this watch communicates through material solidity, not shine.
How long does an artisanally crafted strap last?
A strap constructed with true craftsmanship lasts for years, sometimes decades, with ordinary maintenance. Durability depends on leather quality, buckle integrity, and use conditions. Straps made at <a href="/pages/casati-booking">Casati Milano</a> employ methods and materials designed to age gracefully, developing patina rather than deteriorating.
Why is the Casio G-Shock 6900 considered an icon among tool watches?
Launched in 1995, the 6900 set the standard for extreme durability through its 53mm resin case with three integrated circular displays and the 3230 anti-shock calibre. This combination made it the official instrument in military operations and rescue missions. Its indestructible personality and functional geometry set it apart: it is not an aesthetic watch but a pure instrument without compromise.
