The Heritage

The G-Shock DW-6900SB-2 belongs to the 6900 series of Casio, a line introduced in the 90s. It is equipped with the quartz caliber 3230 with perpetual calendar, chronograph, countdown and alarm functions. The case features the characteristic resin construction with shock protection typical of the G-Shock family.
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 strap on the Casio G-Shock 6900 DW-6900SB-2?

The lug system on the DW-6900SB-2 is not a conventional standard—it is integral to the resin case design. A traditional straight-bar strap will not fit, but a bespoke strap crafted directly onto your watch is entirely possible. <a href="/pages/casati-booking">Casati Milano</a> specialises precisely in this: measuring your case accurately and constructing a strap that fits it perfectly.

How does the bespoke strap construction work for this model?

<a href="/pages/casati-booking">Casati Milano</a> conducts a precise manual survey of the lug attachment on your case: distance between fixing points, depth, thermal tolerances. The strap is then built from scratch with custom lugs geometrically adapted to the resin. The fitting is reversible and does not alter the watch.

What leather suits the character of the Casio G-Shock 6900 DW-6900SB-2?

Leathers with pronounced natural grain—aged Cordovan, vegetable-tanned Full Grain, linen texture—create generative contrast with the rigid geometry of the resin. Warm tones such as chocolate brown, amber, or deep black dialogue naturally with the translucent blue of the case. Avoid glossy leathers, which would negate the watch's sports-oriented character.

How long does a well-made bespoke strap last?

A strap crafted by <a href="/pages/casati-booking">Casati Milano</a> using superior leather and vegetable tanning develops patina over years, improving aesthetically. Structural durability depends on use, but a well-treated Full Grain leather can accompany your watch for decades, evolving in colour and texture without deteriorating.

Why did the Casio G-Shock 6900 DW-6900SB-2 become a cultural icon?

Since 1995, the 6900 model has embodied the intersection of military function and urban aesthetic: the triple digital complication (chronograph, countdown, alarm) housed in a 53-millimetre resin case established itself from hip-hop crews to collectors of alternative haute horlogerie. It proves that "tough luxury" is not a contradiction, but a stylistic grammar where durability is beauty.
