Strap for GD-X6900-1 Black

No, the bracelet is integrated into the case. The attachment is proprietary — a conventional strap won't fit. For this model I work differently — I build the strap directly on the case, bespoke, in the atelier.

Come to <a href="/pages/casati-booking">Atelier Casati Milano</a>, by appointment. I measure the case geometry directly, then shape a strap that sits perfectly on your watch. It's the only approach possible with this integrated system.

I prefer Tuscan vegetable-tanned leather. It has that raw solidity that speaks to the brutal aesthetic of the resin case. It ages well, becomes softer over years, and sustains the sport-military character of the watch with no compromise.

A good strap, with the right leather, lasts years. It depends on how you wear it — the more you wear it, the more the leather breathes and adapts. Care is simple: clean now and then with a damp cloth, let it air dry. Quality leathers age beautifully, develop patina.

Casio designed it in 1983 with one philosophy: extreme resistance, no compromise. The 57.5mm resin tactical case is engineered to shield the movement in harsh conditions. It's not design for design's sake — it's function becoming form. Precisely why it needs a strap that understands this logic, made to measure.
