The Heritage

The G-Shock DW-6900NB-3 belongs to the 6900 series, one of the historic lines of the Casio G-Shock collection. It is equipped with the 3230 quartz caliber with functions of perpetual calendar, chronograph, countdown and alarm. The resin case features the characteristic three-circle design of the 6900 model.
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-6900NB-3?

No, the strap attachment is integrated into the resin case and does not match the geometry of a standard strap with straight bars. However, a custom strap can be built directly onto your case at <a href="/pages/casati-booking">Casati Milano</a>, where the exact geometry of the lugs is measured and the strap is crafted from scratch.

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

The craftsman at Casati Milano examines the watch in the atelier, measures the integrated case lugs using precision calipers, and records the distance, angle, and anchoring shape. The strap is then constructed entirely bespoke, with attachment tabs shaped to accommodate the proprietary geometry of the DW-6900NB-3. It is a craft process that transforms the watch into a unique object.

Which leather is suitable for the character of the Casio G-Shock 6900 DW-6900NB-3?

The 6900 has an urban and anti-formal identity, so robust leathers such as aged calf, hammered alligator, or technical alcantara amplify the industrial tone of the resin case. Marked grains and patinas that evolve over time create a dialogue between the softness of the leather and the hardness of the case. Technical canvas and Cordura also pair perfectly with the model's streetwear character.

How long does a bespoke leather strap last?

A strap crafted by <a href="/pages/casati-booking">Casati Milano</a> using quality leather and artisanal construction lasts for years, often longer than the watch itself. The leather develops a natural patina over time, a testimony to daily wear. Minimal care – occasional cleaning and conditioning – extends the object's useful life even further.

Why has the Casio G-Shock 6900 remained an icon from 1995 to today?

The DW-6900 defined a case aesthetic – the round three-eye form – that has never been surpassed in urban authenticity and immediate recognisability. Unlike many 1990s designs, the 6900 is not dated because it makes no concessions to ornament: every element is functional. Its persistence on the wrists of successive generations of artists and professionals confirms that function, repeated without compromise, becomes immortal iconography.
