The Heritage

The G-Shock 6900 belongs to the line of shock-resistant digital watches developed by Casio in the 1980s. It is equipped with the 3240 caliber with perpetual calendar, chronograph, countdown, and alarm functions. The GD-X6900CM-8 reference features a resin construction with a multi-function digital display.
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 I mount a custom strap on the Casio G-Shock 6900 GD-X6900CM-8?

The GD-X6900CM-8's lug attachment is integral to the case design and does not accept standard straight-bar straps. The solution is a bespoke strap built directly onto the watch, created by <a href="/pages/casati-booking">Casati Milano</a> during an in-studio appointment. The craftsman surveys the proprietary lug proportions and constructs a strap that dialogues naturally with the case geometry.

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

The craftsman at <a href="/pages/casati-booking">Casati Milano</a> examines the watch to understand the lug specifications and case proportions, then listens to your comfort and style needs. The leather portfolio is consulted, finishes and details are selected, and the strap is handcrafted using traditional techniques, calibrated to your wrist dimensions and the lug geometry. It is a co-creative process that transforms the constructive constraint into an authentic personalisation opportunity.

What type of leather is recommended for the Casio G-Shock 6900 GD-X6900CM-8?

The watch's camouflage and sports character suggests pronounced-grain leathers: vegetable-tanned leather, which develops a rich patina over time, or suede with natural veining that absorbs light and harmonises with the resin texture. Cordura and reinforced technical fibres are also legitimate choices for those wishing to maintain a field-focused profile. Material selection affects durability, moisture resistance, and tactile perception on the wrist.

How long does a well-made strap last?

An artisanal strap crafted from quality vegetable-tanned leather using traditional methods lasts years with proper care. Longevity depends on the leather type chosen, intensity of use, and maintenance: proper drying after moisture and occasional conditioning significantly extend lifespan. Unlike factory straps, a well-made strap becomes more characterful with age, developing a patina that tells the story of wear.

Why does the Casio G-Shock 6900 feature an integrated bracelet and not separate lugs?

The integrated lug is a deliberate construction choice ensuring structural rigidity and maximum durability in extreme conditions: every element of the case is engineered to dissipate impact energy and maintain functionality even after shocks that would disable conventional watches. This means a bespoke strap is not a compromise but a logical continuity with Casio's intent: it becomes a natural extension of the design, built to dialogue perfectly with the proportions and philosophy of the model.
